• e192be9d9   random: replace non-blocking pool with a Chacha20-based CRNG ... Browse Code »

  The CRNG is faster, and we don't pretend to track entropy usage in the
  CRNG any more.

• 31d7247da   crypto: chacha20 - Export common ChaCha20 helpers ... Browse Code »

  As architecture specific drivers need a software fallback, export a
  ChaCha20 en-/decryption function together with some helpers in a header
  file.

• c08d0e647   crypto: chacha20 - Add a generic ChaCha20 stream cipher implementation ... Browse Code »

  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.
