EVP_KDF-X942-CONCAT.7ossl - Man Page

The X942 Concat EVP_KDF implementation


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.


This functionality was added in OpenSSL 3.0.
