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. Don't worry! Tcat eliminates tedious configuration tasks. How SSL Works Before we start configuring Tomcat to use SSL, it will help to understand why the SSL protocol was created, and how it works. SSL Basics Why?

Apache Tomcat 8 (8.0.30) - SSL/TLS Configuration HOW-TO 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. To import an existing certificate into a JKS keystore, please read the documentation (in your JDK documentation package) about keytool. To import an existing certificate signed by your own CA into a PKCS12 keystore using OpenSSL you would execute a command like: openssl pkcs12 -export -in mycert.crt -inkey mykey.key -out mycert.p12 -name tomcat -CAfile myCA.crt -caname root -chain For more advanced cases, consult the OpenSSL documentation. To create a new JKS keystore from scratch, containing a single self-signed Certificate, execute the following from a terminal command line: Unix:
