Long time ago when I released the patches now found in [1] and [2] they where 
rejected as it was said, the official route to access the RSA/ECDSA and the 
DH/ECDH ciphers is through the keyring.

Obviously this interface of the keyring is not suitable for testing these 
algorithms. Considering the request that the kernel crypto API ciphers should 
be testable with arbitrary test vectors, would the dusted-off patches for 
AF_ALG KPP and akcipher be accepted?

Ciao
