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 HP Open Source Security for OpenVMS, Volume 2: HP SSL for OpenVMS.
