Secure Hypertext Transfer Protocol
Web encryption method similar to HTTPS / From Wikipedia, the free encyclopedia
Not to be confused with HTTPS.
Secure Hypertext Transfer Protocol (S-HTTP) is an obsolete alternative to the HTTPS protocol for encrypting web communications carried over the Internet. It was developed by Eric Rescorla and Allan M. Schiffman at EIT in 1994[1] and published in 1999 as RFC 2660.
Even though S-HTTP was first to market,[2] Netscape's dominance of the browser market led to HTTPS becoming the de facto method for securing web communications.
