Description: TLS V1.2 protocol support is provided according to RFC 5246, for establishing secure connections between two communicating partners. TLS V1.2 adds support for exploiters to use higher strength cryptographic ciphers. TLS V1.2 main objectives are to replace the standard SHA-1/MD5 pseudorandom function (PRF) with a cipher-based PRF based on SHA-256, add support for SHA-256 based ciphers and allow client applications to specify what signature/hash values are supported for digital signatures.
When change was introduced: This function is available for z/OS® V2R1 and rolled back to z/OS V1R13 with PTFs for APAR OA39422.
