A cipher is an instance of AES encryption using a particular key.

aesCipherGCM implements crypto/cipher.gcmAble so that crypto/cipher.NewGCM will use the optimised implementation in this file when possible. Instances

cbcDecAble is implemented by cipher.Blocks that can provide an optimized implementation of CBC decryption through the cipher.BlockMode interface. See

cbcEncAble is implemented by cipher.Blocks that can provide an optimized implementation of CBC encryption through the cipher.BlockMode interface. See

ctrAble is implemented by cipher.Blocks that can provide an optimized implementation of CTR through the cipher.Stream interface. See crypto/cipher/ctr

gcmAble is implemented by cipher.Blocks that can provide an optimized implementation of GCM through the AEAD interface. See crypto/cipher/gcm.go.

This file contains two implementations of AES-GCM. The first implementation (gcmAsm) uses the KMCTR instruction to encrypt using AES in counter mode a

gcmHashKey represents the 16-byte hash key required by the GHASH algorithm.

gcmKMA implements the cipher.AEAD interface using the KMA instruction. It should only be used if hasKMA is true.

testAEAD implements the cipher.AEAD interface.

testBlock implements the cipher.Block interface and any *Able interfaces that need to be tested.

testBlockMode implements the cipher.BlockMode interface.

Check that the optimized implementations of cipher modes will be picked up correctly. testInterface can be asserted to check that a type originates fr

testStream implements the cipher.Stream interface.
