Frank Denis 5dff93005e Drastically improve the password hashing functions 
Password hashing functions are designed to be slow.

Make them slower, but also useful.

Frank Denis d47ded1867 Only memset() may have issues with a zero length. 2019-02-09 20:28:41 +01:00
Ilya Maykov 6934a8d0c8 Relax most __attribute__ ((nonnull)) to allow 0-length inputs to be NULL. 
Justifications:
- crypto_(auth|hash|generichash|onetimeauth|shorthash)*:
  it's legal to hash or HMAC a 0-length message
- crypto_box*: it's legal to encrypt a 0-length message
- crypto_sign*: it's legal to sign a 0-length message
- utils:
  comparing two 0-length byte arrays is legal
  memzero on a 0-length byte array is a no-op
  converting an empty hex string to binary results in an empty binary string
  converting an empty binary string to hex results in an empty hex string
  converting an empty b64 string to binary results in an empty binary string
  converting an empty binary string to b64 results in an empty b64 string
  sodium_add / sodium_sub on zero-length arrays is a no-op

For the functions declared in utils.h, I moved the logic into private functions that
have the __attribute__ ((nonnull)) check, but they are only called when the
corresponding length argument is non-0. I didn't do this for the hash/box/sign
functions since it would have been a lot more work and quite a large refactor.

Frank Denis b3725dc2c9 Force clear the high bit in _noclamp variants 
_noclamp variants should always be used with a scalar < L, but
if this is not the case, at least explicitly ignore the high bit.
