!!! Overview
[{$pagename}] is [TLS] version 1.2  has a Version protocol ID of 0x0303

[{$pagename}] was defined in [RFC 5246] in August 2008. It is based on the earlier [TLS 1.1] specification. 

[{$pagename}] is the only version of [TLS] that is supported by [Recommendations for Secure Use of Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS)]

This protocol was defined in [RFC 5246] in August of [2008|Year 2008] and is based on [TLS 1.1], however, [{$pagename}] contains improved flexibility. 

The major differences in [{$pagename}] include:
* The [MD5]/[SHA-1] combination in the [pseudorandom function] ([PRF]) was replaced with [cipher-suite-specified|Cipher Suite] [PRFs].
* The [MD5]/[SHA-1] combination in the digitally-signed element was replaced with a single hash.  Signed elements include a field explicitly specifying the hash algorithm used.
* There was substantial cleanup to the client's and server's ability to specify which [hash] and [Digital Signature] [algorithms] they will accept.
* Addition of support for [Authenticated Encryption with Associated Data] with additional data modes.
* [TLS extensions] definition and [AES] [Cipher Suites] were merged in.
* Tighter checking of [EncryptedPreMasterSecret] version numbers.
* Many of the requirements were tightened
* Verify_data length depends on the [Cipher Suite]
* Description of Bleichenbacher/Dlima [attack] defenses cleaned up.!! More Information
