| * | BACKPORT: crypto: chacha20 - Export common ChaCha20 helpers | Martin Willi | 2017-12-14 | 1 | -16/+12 |
| | | | | | | | | | | | | | | As architecture specific drivers need a software fallback, export a ChaCha20 en-/decryption function together with some helpers in a header file.

| * | UPSTREAM: crypto: chacha20 - Add a generic ChaCha20 stream cipher implementation | Martin Willi | 2017-12-14 | 1 | -0/+216 |
| 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.
