The next three patches add support for keys stored in system keyring subsystem. First patch adds algif_akcipher nokey hadlers. Second patch adds generic sign, verify, encrypt, decrypt accessors functions to the asymmetric key type. These will be defined by asymmetric subtypes, similarly to how public_key currently defines the verify_signature function. Third patch adds support for ALG_SET_KEY_ID and ALG_SET_PUBKEY_ID commands to AF_ALG and setkeyid operation to the af_alg_type struct. If the keyid is used then the afalg layer acquires the key for the keyring subsystem and uses the new asymmetric accessor functions instead of akcipher api. The asymmetric subtypes can use akcipher api internally.
