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:

    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
