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.
"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.
