New in NSS 3.25

New Functionality

• Implemented DHE key agreement for TLS 1.3
• Added support for ChaCha with TLS 1.3
• Added support for TLS 1.2 ciphersuites that use SHA384 as the PRF
• In previous versions, when using client authentication with TLS 1.2, NSS only supported certificate_verify messages that used the same signature hash algorithm as used by the PRF. This limitation has been removed.
• Several functions have been added to the public API of the NSS Cryptoki Framework.

New Functions

• in nssckfw.h
  • NSSCKFWSlot_GetSlotID
  • NSSCKFWSession_GetFWSlot
  • NSSCKFWInstance_DestroySessionHandle
  • NSSCKFWInstance_FindSessionHandle

Compatibility

NSS 3.25 shared libraries are backward compatible with all older NSS 3.x shared libraries. A program linked with older NSS 3.x shared libraries will work with NSS 3.25 shared libraries without recompiling or relinking. Furthermore, applications that restrict their use of NSS APIs to the functions listed in NSS Public Functions will remain compatible with future versions of the NSS shared libraries.
