To successfully install your SSL Certificate on a, you will need to configure the root (SSL) certificate, intermediate/primary certificate, and private key within the appropriate keystore. Perform the following steps when installing the SSL certificate on a Tomcat Web Server. Install SSL Certificate into the Keystore - Step 1: Download And Extract SSL Certificate After order completion, Certificate Authority (CA) will send an email containing a.zip file which includes the root, intermediate, & primary certificate files. Download and extract the files on the Tomcat Web Server directory where the Keystore was added during the Certificate Signing Request (CSR) generation process. Note: SSL certificate will work only with the same keystore, which was created during the CSR generation process.
Also, make sure to install all certificate files in the correct order on the keystore. Step 2: Installation of the Root Certificate File During the procedure of installing an SSL certificate to the keystore, the password required is the same one that you created during the CSR generation process. Now, to install the Root certificate file, enter the following command/code: keytool -import -trustcacerts -alias root -file RootCertFileName.crt -keystore keystore.key After entering this command, if you receive a message that says “Certificate already exists in system-wide CA Keystore under alias Do you still want to add it to your own Keystore? no:” then select Yes. If this process is successfully completed, it will display s this message: “ Certificate was added to Keystore”. Step 3: Installation of the Intermediate Certificate File Add the following command/code to install the intermediate certificate file: keytool -import -trustcacerts -alias intermediate -file IntermediateCertFileName.crt -keystore keystore.key If this process is successfully completed, it will display this message: “Certificate was added to Keystore”. Step 4: Installing the Primary Certificate File Add the following command/code install the primary certificate file: keytool -import -trustcacerts -alias tomcat -file PrimaryCertFileName.crt -keystore keystore.key If this process is successfully completed, it will display this message: “Certificate was added to Keystore”.

After installing the SSL Certificate file into your keystore, the next step is the ‘S erver Configuration’ for using the Keystore file. SSL Connector Configuration - Note: Configuration of ‘SSL Connector’ must be required for Tomcat to accept a secure connection.
In the system’s home directory, Tomcat is mainly looking for the Keystore with file name ‘.keystore’ with default password as ‘changeit’. On Unix and Linux systems, the home directory will be /home/user-name/ and for Microsoft windows systems C: Documents and Settings user-name. Users can change the file location and password if required. Copy Keystore file (your-domain-name.key) into the home directory 2. Now, using any text-editor open /conf/server.xml file.
If necessary, uncomment the SSL connector. Locate the SSL connector for which the new Keystore will be used. Make sure the Connector Port is 443. During configuration of SSL connector, add the exact location of Keystore file name and also the correct KeystorePass.
If the Tomcat version is 7.0.X or 8.0.X, then replace the KeystorePass with Keypass Once the connector configuration process is finished, it will look something like this: 7. Save the server.xml file and restart Tomcat server. With this step, the SSL certificate gets successfully installed on Tomcat web Server. Resources:.

A Simple Step-By-Step Guide To Apache Tomcat SSL Configuration Secure Socket Layer (SSL) is a protocol that provides security for communications between client and server by implementing encrypted data and certificate-based authentication. Technically, the term 'SSL' now refers to the Transport Layer ouSecurity (TLS) protocol, which is based on the original SSL specification. SSL is one of the most common ways of integrating secure communication on the internet, as it is a mature protocol that is well-supported by every major browser and a number of well-respected organizations provide third party SSL authentication services.
If you're using Apache Tomcat, chances are that at least some of the data you're handling is sensitive, and SSL is an easy way to offer your users security. The good news is that Tomcat fully supports the SSL protocol. The bad news is that the configuration process and SSL itself can be a little confusing for first-time users. To help you get SSL working with your Tomcat servers, we've assembled a simple, comprehensive, step-by-step guide to using SSL with Tomcat. From an overview of how the protocol actually works, to clear, simple configuration instructions, this guide will help you get SSL running on your server in no time.
Eliminates tedious configuration tasks. Create the correct configuration a single time, save it to a server profile, and apply it to other instances (or groups of instances) with a single click. Try, click here to jump to a step-by-step configuration guide. SSL Basics The SSL protocol aims to provide solutions to two simple security problems:. How can we securely transmit data between two parties in such a way that only the two parties can read it?. How can one (or more) of the parties involved prove that they are actually the entity we want to grant the ability to decrypt our encrypted transmission? SSL's answer to the first question is encryption.
Before transmitting any data, the sender encrypts its message, and the receiver must in turn decrypt the message before processing it. The encryption and decryption is accomplished through a method called 'public key encryption.' SSL's answer to the second question is also part of the answer to the first question. In order for public key encryption to provide secure communication, one more more of the communicating parties must have some way of proving to the other that they are, in fact, who they claim to be. SSL provides this proof by requiring that one or more of the parties present a digital certificate into the initial negotiation of the connection, prior to the transmission of any encrypted data. This process is called 'handshaking.' To ensure that the certificate is a valid proof of identity, SSL contacts a trusted third party server specified in the certificate, called a Certificate Authority (CA).
A Certificate Authority is a trusted company that agrees to vouch for the identity of a site, usually for a fee. Generally, the more widely the CA is known as a reputable organization, the more they will charge you per year to verify your site's identity. Examples of well-respected CA's include and. HTTP The most common way that SSL is integrated into Internet communications is through the HTTPS protocol. Calling HTTPS a 'protocol' is not entirely accurate, as it is simply a combination of the HTTP and SSL protocols. When we say a message was sent using HTTPS, what we are actually saying is that the message was first encrypted using SSL, transmitted and received using normal HTTP protocol, and then decrypted by the receiver, also with SSL. So that's SSL in a (very basic) nutshell.
To sum up:. SSL offers security through encryption. the encryption process is made possible through the use of digital certificates verified by a third party Certificate Authority. the most common implementation of this process is the HTTPS combination protocol.

Now, let's get SSL working with your Tomcat Server. Using SSL With Tomcat to use SSL connections can be a bit tricky the first time around, but if you follow this step by step guide, you should it up and running in no time. When To Use SSL With Tomcat Before you go through the trouble of getting SSL up and running, it's a probably a good idea to determine if you actually should be using this configuration.
The most common reason you'd need to use Tomcat to handle SSL connections would be if you are running Tomcat as a stand-alone web server. In other words, if you're fronting Tomcat with a web server and using it only as an application server or container, in most cases you should let the web server function as a proxy for all SSL requests. Because all that decryption, encryption, and handshaking isn't free - actually, it's not just 'not free,' it's quite CPU-intensive, and it significantly slows down the speed of transmission. In other words, if you're already using a web server to serve your static content, you're better off letting it handle all that, freeing up your Tomcat server to focus on its specialty - quickly generating dynamic content, and allowing it to get that data to your web server as quickly as possible, in cleartext. If, however, your site is small enough that you don't need to mess around with an additional web server, then Tomcat will happily handle your SSL needs. Here's how to get it working.
Configuring Tomcat To Use SSL Setting up SSL for Tomcat can be pided into two main tasks: creating a functional keystore, and configuring the Tomcat connectors and applications. Let's tackle them one at a time. PART I - The Keystore Step 1 - Creating the Keystore The keys Tomcat will use for SSL transactions are stored in a password-protected file called, creatively, the 'keystore.' The first step to enabling SSL on your server is to create and edit this file. You can create this file in one of two ways - by importing an existing key into the keystore, or by creating an entirely new key.
In the interest of simplicity, this guide will only cover the latter (but you can find instructions for importing keys on Apache's ). A program called keytool, which is included with your JDK, will do the actual work of creating your new keystore. To create a new keystore using this program, enter the following command at the command-line, substituting syntax appropriate for your OS: $JAVAHOME/bin/keytool -genkey -alias youralias -keyalg RSA -keystore /preferred/keystore/path Use an alias and path of your choice. Next, keytool will ask you to enter the password you want to use for the keystore.
Again, choose whatever you like (but don't forget it). After you choose the keystore password, you will enter the information required for the Certificate, such as your company and your name. Make sure this information is accurate, as you will have to submit this file to the Certificate Authority of your choice to obtain a certificate.
The last thing keytool will ask you to specify is the key password, which is the password specific to this specific certificates. Rather than enter anything at this prompt, just press ENTER. This will cause keytool to set the key password to a value equivalent to the keystore password. Matching passwords are REQUIRED for Tomcat to access the certificate. If you choose two different passwords, any attempts to access the keystore will result in a crash (so don't do it). Congratulations - if you followed the directions correctly, you should now have a usable keystore file named youralias, located in the directory you chose. Step 2 - Creating the Certificate Signing Request Now that you've created your keystore, it's time to create a file called the Certificate Signing Request, or CSR, which will be used by the Certificate Authority of your choice to generate the Certificate SSL will present to other parties during the handshake.
You can use the keytool to create this file, as well. To do so, enter the following at the command line: $JAVAHOME/bin/keytool -certreq -keyalg RSA -alias youralias -file yourcertificatname.csr -keystore path/to/your/keystore Substitute the values you chose earlier for the placeholders.
If you follow the instructions correctly, keytool will create a file called yourcertificatename.csr, which you can submit to the CA you've chosen via the process they provide on their website. Using this file, they will generate a custom certificate for your server, which you can download according to the instructions they provide on their website. Step 3 - Installing Your New Certificate Getting tired yet? Don't worry - there's light at the end of the tunnel.
This is the last thing you'll need to do to create a keystore for Tomcat to use. Well, the last two things. Hang in there!
SSL verifies the authenticity of a site's certificate by using something called a 'chain of trust,' which basically means that during the handshake, SSL initiates an additional handshake with the Certificate Authority specified in your site's certificate, to verify that you haven't simply made up your own CA. In order to 'anchor' your certificate's chain of trust, you have to download an additional certificate, called a 'Root Certificate,' from your CA, and then import both this certificate and your site's new certificate into your keystore. Your CA should provide information about obtaining a Root Certificate on their website. Once you've downloaded both your own Certificate and the Root certificate provided by your CA, import them into your keystore with the following commands, replacing the placeholders: To import the Root Certificate - keytool -import -alias root -keystore path/to/your/keystore -trustcacerts -file path/to/the/rootcertificate To import your new Certificate - keytool -import -alias youralias -keystore path/to/your/keystore -file path/to/yourkeystore Do everything right? Then pat yourself on the back - you are now the proud owner of a functional, certified keystore.
PART II - Configuring Tomcat to use SSL Now that we have a functional keystore populated with valid certificates, it's time to configure Tomcat to use SSL. First, we'll configure Tomcat's SSL connectors, and then we'll specify which webapps we want to use SSL by default. Step 1 - Configuring Tomcat's SSL Connectors options are configured in Tomcat's main configuration file, '$CATALINABASE/conf/server.xml', so you should open this file now. By using MuleSoft brand materials, you agree to the MuleSoft Terms of Service, these MuleSoft branding guidelines, and all MuleSoft rules and policies, as may be updated from time to time. You also acknowledge that MuleSoft is the sole owner of MuleSoft trademarks, promise not to interfere with MuleSoft’s rights in them, and acknowledge that goodwill derived from their use accrues only to MuleSoft. MuleSoft may review use of the branding materials at any time and reserves the right to terminate or modify any use.
The description below uses the variable name $CATALINABASE to refer the base directory against which most relative paths are resolved. If you have not configured Tomcat for multiple instances by setting a CATALINABASE directory, then $CATALINABASE will be set to the value of $CATALINAHOME, the directory into which you have installed Tomcat. To install and configure SSL/TLS support on Tomcat, you need to follow these simple steps.
For more information, read the rest of this HOW-TO. Create a keystore file to store the server's private key and self-signed certificate by executing the following command: Windows. Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are technologies which allow web browsers and web servers to communicate over a secured connection. This means that the data being sent is encrypted by one side, transmitted, then decrypted by the other side before processing. This is a two-way process, meaning that both the server AND the browser encrypt all traffic before sending out data. Another important aspect of the SSL/TLS protocol is Authentication.
This means that during your initial attempt to communicate with a web server over a secure connection, that server will present your web browser with a set of credentials, in the form of a 'Certificate', as proof the site is who and what it claims to be. In certain cases, the server may also request a Certificate from your web browser, asking for proof that you are who you claim to be. This is known as 'Client Authentication,' although in practice this is used more for business-to-business (B2B) transactions than with individual users. Most SSL-enabled web servers do not request Client Authentication. SSL/TLS and Tomcat. It is important to note that configuring Tomcat to take advantage of secure sockets is usually only necessary when running it as a stand-alone web server.
Details can be found in the. When running Tomcat primarily as a Servlet/JSP container behind another web server, such as Apache or Microsoft IIS, it is usually necessary to configure the primary web server to handle the SSL connections from users. Typically, this server will negotiate all SSL-related functionality, then pass on any requests destined for the Tomcat container only after decrypting those requests. Likewise, Tomcat will return cleartext responses, that will be encrypted before being returned to the user's browser. In this environment, Tomcat knows that communications between the primary web server and the client are taking place over a secure connection (because your application needs to be able to ask about this), but it does not participate in the encryption or decryption itself. In order to implement SSL, a web server must have an associated Certificate for each external interface (IP address) that accepts secure connections.
The theory behind this design is that a server should provide some kind of reasonable assurance that its owner is who you think it is, particularly before receiving any sensitive information. While a broader explanation of Certificates is beyond the scope of this document, think of a Certificate as a 'digital passport' for an Internet address. It states which organisation the site is associated with, along with some basic contact information about the site owner or administrator. This certificate is cryptographically signed by its owner, and is therefore extremely difficult for anyone else to forge. For the certificate to work in the visitors browsers without warnings, it needs to be signed by a trusted third party.
These are called Certificate Authorities (CAs). To obtain a signed certificate, you need to choose a CA and follow the instructions your chosen CA provides to obtain your certificate. A range of CAs is available including some that offer certificates at no cost. Java provides a relatively simple command-line tool, called keytool, which can easily create a 'self-signed' Certificate. Self-signed Certificates are simply user generated Certificates which have not been signed by a well-known CA and are, therefore, not really guaranteed to be authentic at all. While self-signed certificates can be useful for some testing scenarios, they are not suitable for any form of production use.
General Tips on Running SSL. When securing a website with SSL it's important to make sure that all assets that the site uses are served over SSL, so that an attacker can't bypass the security by injecting malicious content in a javascript file or similar.
To further enhance the security of your website, you should evaluate to use the HSTS header. It allows you to communicate to the browser that your site should always be accessed over https. Using name-based virtual hosts on a secured connection requires careful configuration of the names specified in a single certificate or Tomcat 8.5 onwards where Server Name Indication (SNI) support is available.
SNI allows multiple certificates with different names to be associated with a single TLS connector. Tomcat currently operates only on JKS, PKCS11 or PKCS12 format keystores. The JKS format is Java's standard 'Java KeyStore' format, and is the format created by the keytool command-line utility. This tool is included in the JDK.
The PKCS12 format is an internet standard, and can be manipulated via (among other things) OpenSSL and Microsoft's Key-Manager. Each entry in a keystore is identified by an alias string. Whilst many keystore implementations treat aliases in a case insensitive manner, case sensitive implementations are available.
The PKCS11 specification, for example, requires that aliases are case sensitive. To avoid issues related to the case sensitivity of aliases, it is not recommended to use aliases that differ only in case. To import an existing certificate into a JKS keystore, please read the documentation (in your JDK documentation package) about keytool. Note that OpenSSL often adds readable comments before the key, but keytool does not support that. So if your certificate has comments before the key data, remove them before importing the certificate with keytool. To import an existing certificate signed by your own CA into a PKCS12 keystore using OpenSSL you would execute a command like.
$JAVAHOME/bin/keytool -genkey -alias tomcat -keyalg RSA (The RSA algorithm should be preferred as a secure algorithm, and this also ensures general compatibility with other servers and components.) This command will create a new file, in the home directory of the user under which you run it, named '.keystore'. To specify a different location or filename, add the -keystore parameter, followed by the complete pathname to your keystore file, to the keytool command shown above. You will also need to reflect this new location in the server.xml configuration file, as described later. For example: Windows. $JAVAHOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore /path/to/my/keystore After executing this command, you will first be prompted for the keystore password. The default password used by Tomcat is ' changeit' (all lower case), although you can specify a custom password if you like. You will also need to specify the custom password in the server.xml configuration file, as described later.
Next, you will be prompted for general information about this Certificate, such as company, contact name, and so on. This information will be displayed to users who attempt to access a secure page in your application, so make sure that the information provided here matches what they will expect.
Finally, you will be prompted for the key password, which is the password specifically for this Certificate (as opposed to any other Certificates stored in the same keystore file). The keytool prompt will tell you that pressing the ENTER key automatically uses the same password for the key as the keystore. You are free to use the same password or to select a custom one.
If you select a different password to the keystore password, you will also need to specify the custom password in the server.xml configuration file. If everything was successful, you now have a keystore file with a Certificate that can be used by your server.
Tomcat can use two different implementations of SSL:. the JSSE implementation provided as part of the Java runtime (since 1.4). the APR implementation, which uses the OpenSSL engine by default.

The exact configuration details depend on which implementation is being used. If you configured Connector by specifying generic protocol='HTTP/1.1' then the implementation used by Tomcat is chosen automatically. If the installation uses - i.e. You have installed the Tomcat native library - then it will use the APR SSL implementation, otherwise it will use the Java JSSE implementation. As configuration attributes for SSL support significantly differ between APR vs. JSSE implementations, it is recommended to avoid auto-selection of implementation.

It is done by specifying a classname in the protocol attribute of the. To define a Java (JSSE) connector, regardless of whether the APR library is loaded or not, use one of the following.
SSLRandomSeed allows to specify a source of entropy. Productive system needs a reliable source of entropy but entropy may need a lot of time to be collected therefore test systems could use no blocking entropy sources like '/dev/urandom' that will allow quicker starts of Tomcat. The final step is to configure the Connector in the $CATALINABASE/conf/server.xml file, where $CATALINABASE represents the base directory for the Tomcat instance. An example element for an SSL connector is included in the default server.xml file installed with Tomcat. To configure an SSL connector that uses JSSE, you will need to remove the comments and edit it so it looks something like this.
This allows Tomcat to automatically redirect users who attempt to access a page with a security constraint specifying that SSL is required, as required by the Servlet Specification. After completing these configuration changes, you must restart Tomcat as you normally do, and you should be in business. You should be able to access any web application supported by Tomcat via SSL. For example, try. Now that you have your Certificate you can import it into you local keystore. First of all you have to import a so called Chain Certificate or Root Certificate into your keystore.
After that you can proceed with importing your Certificate. Download a Chain Certificate from the Certificate Authority you obtained the Certificate from. For Verisign.com commercial certificates go to: For Verisign.com trial certificates go to: For Trustcenter.de go to: For Thawte.com go to:.

To generate an OCSP-enabled certificate:. Create a private key. This is a new feature in the Servlet 3.0 specification. Because it uses the SSL session ID associated with the physical client-server connection there are some limitations. They are:. Tomcat must have a connector with the attribute isSecure set to true. If SSL connections are managed by a proxy or a hardware accelerator they must populate the SSL request headers (see the ) so that the SSL session ID is visible to Tomcat.
If Tomcat terminates the SSL connection, it will not be possible to use session replication as the SSL session IDs will be different on each node. To enable SSL session tracking you need to use a context listener to set the tracking mode for the context to be just SSL (if any other tracking mode is enabled, it will be used in preference).

It might look something like. // Standard HTTP session invalidation session.invalidate; // Invalidate the SSL Session org.apache.tomcat.util.net.SSLSessionManager mgr = (org.apache.tomcat.util.net.SSLSessionManager) request.getAttribute('javax.servlet.request.sslsessionmgr'); mgr.invalidateSession; // Close the connection since the SSL session will be active until the connection // is closed response.setHeader('Connection', 'close'); Note that this code is Tomcat specific due to the use of the SSLSessionManager class. This is currently only available for the BIO, NIO and NIO2 connectors, not the APR/native connector.
Install Tomcat 8 On Windows
Step 1: Install Tomcat from Binary First, head-on-over to the site. Then, under the heading 8.0.9 (the current version as of July 2014), or whichever is the newest version at the time you read this article, you’ll see Binary Distributions. Under Binary Distributions you’ll see Core and then tar.gz. Right click on tar.gz and copy the URL. From your server, download Apache Tomcat 8 from the URL you copied in the previous step: wget http://mirrors.ibiblio.org/apache/tomcat/tomcat-8/v8.0.9/bin/apache-tomcat-8.0.9.tar.gz. Step 4: Test Run Tomcat and Java should now be installed and configured on your server.
To activate Tomcat, run the following script: $CATALINAHOME/bin/startup.sh You should get a result similar to: Using CATALINABASE: /opt/tomcat Using CATALINAHOME: /opt/tomcat Using CATALINATMPDIR: /opt/tomcat/temp Using JREHOME: /usr/lib/jvm/java-7-openjdk-amd64/ Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar Tomcat started. Verify that Tomcat is working by visiting theIPofyourserver:8080. For example: http://127.0.0.1:8080.
