NAME

       EVP_KDF-X942-CONCAT - The X942 Concat EVP_KDF implementation

DESCRIPTION

       The EVP_KDF-X942-CONCAT algorithm is identical to EVP_KDF-X963. It is used for key
       agreement to derive a key using input such as a shared secret key and shared info.

   Identity
       "X942KDF_CONCAT" is the name for this implementation; it can be used with the
       EVP_KDF_fetch() function.

       This is an alias for "X963KDF".

       See EVP_KDF-X963(7) for a list of supported parameters and examples.
