2015-06-17	crypto: poly1305 - Pass key as first two message blocks to each desc_ctx	Martin Willi	1	-23/+31
	The Poly1305 authenticator requires a unique key for each generated tag. This implies that we can't set the key per tfm, as multiple users set individual keys. Instead we pass a desc specific key as the first two blocks of the message to authenticate in update().

2015-06-04	crypto: chacha20poly1305 - Add an IPsec variant for RFC7539 AEAD	Martin Willi	1	-1/+25
	draft-ietf-ipsecme-chacha20-poly1305 defines the use of ChaCha20/Poly1305 in ESP. It uses additional four byte key material as a salt, which is then used with an 8 byte IV to form the ChaCha20 nonce as defined in the RFC7539.

2015-06-04	crypto: chacha20poly1305 - Add a ChaCha20-Poly1305 AEAD construction, RFC7539	Martin Willi	1	-0/+663
	This AEAD uses a chacha20 ablkcipher and a poly1305 ahash to construct the ChaCha20-Poly1305 AEAD as defined in RFC7539. It supports both synchronous and asynchronous operations, even if we currently have no async chacha20 or poly1305 drivers.
