Evgenii Stratonikov 225b24f7f4 Allow to use hash in Sign*/Verify* 
Sometimes having a whole buffer in memory isn't desired.
New interface allows us to provide hashes instead.

alexvanin 1461d7a248 rfc6979: Add leading zeros if `r` or `s` has less than 32 bytes 
SignECDSA function returns two coordinates on elliptic curve.
Catenation of these coordinates is a 64 byte signature. If
one of these coordinates have less than 32 significant bytes, then
it should have leading zeros.

Merge pull request #8 from nspcc-dev/fix/compress-31-byte-x-point 
Fix point encoding for short X coordinate
 2019-11-18 13:36:21 +03:00
alexvanin f5ad619450 Fix point encoding for short X coordinate 
Public keys can have X coordinate value shorter than 32 byte.
In this case `encodePoint()` should return 32 byte value with
leading zeros.

This commit also adds unit test for public key with 31 byte
X coordinate value.

Merge pull request #3 from nspcc-dev/fix-naming 
Use consistent parameter names for Sign and Verify functions
 2019-11-12 15:28:54 +03:00
alexvanin 8fa65a0afc Use consistent parameter names for Sign and Verify functions 
It may be misleading when verify function takes signature as a hash
parameter. This commit suggested to use rfc6979 original naming
for the parameters:
- `msg` as the message to sign,
- `sig` as the signature of message.
All hashing operations are encapsulated inside of the Sign
and Verify functions.

Also there are comment fixes and re-usage of `hashBytes()` in rfc6979.
