I assume TLS 1.2 is a protocol for crytography, and SHA-2 is an advaced encryption algorithm.

Given that is SHA-2 a  required component of TLS 1.2

Is SHA-2 a component of any other  protocols (rx: TLS 1.0, 1.1)

Is there a difference between SHA-2 and SHA-256 ?  (I am think there is no difference, just want to check)

Thanks in advance

TLS (Transport Layer Security) is the successor to SSL and is used to encrypt transmissions over the network and the web.  http://en.wikipedia.org/wiki/Transport_Layer_Security

SHA is Secure Hash Algorithm http://en.wikipedia.org/wiki/Secure_Hash_Algorithm .  SHA-256 is a part of SHA-2.

A HASH is a one-way algorithm and not a two way-encryption method.  SHA-256 is used in TLS 1.2 to create a 'random number', not to do the encryption.  http://en.wikipedia.org/wiki/Transport_Layer_Security#TLS_1.2
