crypto: chacha20 - Add a generic ChaCha20 stream cipher implementation 2015-06-04T07:04:49+00:00 Martin Willi martin@strongswan.org 2015-06-01T11:43:56+00:00 c08d0e647305c3f8f640010a56c9e4bafb9488d3 ChaCha20 is a high speed 256-bit key size stream cipher algorithm designed by Daniel J. Bernstein. It is further specified in RFC7539 for use in IETF protocols as a building block for the ChaCha20-Poly1305 AEAD. This is a portable C implementation without any architecture specific optimizations. It uses a 16-byte IV, which includes the 12-byte ChaCha20 nonce prepended by the initial block counter. Some algorithms require an explicit counter value, for example the mentioned AEAD construction.
