The Secure Sockets Layer (SSL) was first developed by Netscape to secure browser-to-web-server communication channels. OpenSSL is an industry-standard package of cryptographic services that provides SSL and Transaction Layer Security (TLS) protocols. Additionally, OpenSSL provides client/server authentication, encryption, and message integrity services for secure communications on the TCP/IP protocol. For more information, see the VSI Open Source Security for OpenVMS, Volume 2: VSI SSL for OpenVMS. To check whether VSI SSL is installed on your system, enter the following command: $ PRODUCT SHOW PRODUCT SSL If VSI SSL is installed on your system, you can find the release notes by entering the following command: $ DIRECTORY SYS$HELP:SSL*.RELEASE_NOTES NOTE NOTE: For information about System Service Logging (SSLOG)-a totally different utility- see help for SSLOG, ANALYZE/SSLOG, and SET PROCESS/SSLOG.
