Piotr Dyraga 2890f060b7 core/vm, crypto/blake2b: add BLAKE2b compression func at 0x09 ... The precompile at 0x09 wraps the BLAKE2b F compression function: https://tools.ietf.org/html/rfc7693#section-3.2 The precompile requires 6 inputs tightly encoded, taking exactly 213 bytes, as explained below. - `rounds` - the number of rounds - 32-bit unsigned big-endian word - `h` - the state vector - 8 unsigned 64-bit little-endian words - `m` - the message block vector - 16 unsigned 64-bit little-endian words - `t_0, t_1` - offset counters - 2 unsigned 64-bit little-endian words - `f` - the final block indicator flag - 8-bit word [4 bytes for rounds][64 bytes for h][128 bytes for m][8 bytes for t_0] [8 bytes for t_1][1 byte for f] The boolean `f` parameter is considered as `true` if set to `1`. The boolean `f` parameter is considered as `false` if set to `0`. All other values yield an invalid encoding of `f` error. The precompile should compute the F function as specified in the RFC (https://tools.ietf.org/html/rfc7693#section-3.2) and return the updated state vector `h` with unchanged encoding (little-endian). See EIP-152 for details.		2019-08-21 13:09:15 +03:00
