'''TLS''' ('''Transport Layer Security''') is a networking protocol that adds encryption and authentication features to other protocols. It is the successor to '''SSL''' ('''Secure Sockets Layer'''), which was originally developed by Netscape. TLS v1.0 is essentially "SSLv3.1", with a different name.

The most familiar protocol that uses TLS is '''HTTPS''', a more-secure version of the [[HTTP]] protocol used on the [[Web]].

== STARTTLS ==
TLS can be implemented in two fundamentally different ways.

In one, a separate [[TCP]] port is assigned to the TLS version of the protocol. This is the only method supported by HTTPS.

In another, sometimes called '''STARTTLS''' or '''Opportunistic TLS''', the same TCP port is used for both secure and insecure communications. To enable security, the client issues some sort of "STARTTLS" command after establishing the (initially unsecured) connection. This is supported by [[LDAP]], [[IMAP]], etc.

== Disambiguation ==
'''TLS''' can mean:
* A collective name for SSL and TLS.
* TLS version 1.0 and higher, specifically excluding SSL.
* Various "STARTTLS" commands and their associated protocols.

'''SSL''' can mean:
* A collective name for SSL and TLS.
* SSL through SSLv3, specifically excluding TLS.
* The use of a special port for SSL/TLS protocols, specifically excluding "STARTTLS" mechanisms.
