Examples with JSSEKeyManager org.apache.tomcat.util.net.jsse.JSSEKeyManager used on opensource projects

Example 1 with JSSEKeyManager

use of org.apache.tomcat.util.net.jsse.JSSEKeyManager in project tomcat by apache.

the class SSLUtilBase method getKeyManagers.

         * Use an in memory key store where possible.
         * For PEM format keys and certificates, it allows them to be imported
         * into the expected format.
         * For Java key stores with PKCS8 encoded keys (e.g. JKS files), it
         * enables Tomcat to handle the case where multiple keys exist in the
         * key store, each with a different password. The KeyManagerFactory
         * can't handle that so using an in memory key store with just the
         * required key works around that.
         * Other keys stores (hardware, MS, etc.) will be used as is.
