  o Minor features (crypto):
    - When allocating a digest state object, allocate no more space than we
      actually need.  Previously, we were allocating as much space as the
      state for the largest algorithm would need.  This change saves up to
      672 bytes per circuit.  Closes ticket 17796.
When allocating a crypto_digest_t, allocate no more bytes than needed Previously we would allocate as many bytes as we'd need for a keccak--even when we were only calculating SHA1. Closes ticket 17796. 2015-12-20 21:15:11 +01:00			`o Minor features (crypto):`
