SHA256 counter tests.

The tests verify that the SHA256 counter doesn't wrap around at message length 2^i bytes for i = 20, ..., 33. This wide range aims at being independent of the implementation of the counter and it catches multiple natural 32-bit overflows (e.g., counting bits, counting bytes, counting blocks, ...).

The test vectors have been generated using following Python script which relies on https://github.com/cloudtools/sha256/ (v0.3 on Python v3.10.2).

from sha256 import sha256
from copy import copy
 
def midstate_c_definition(hasher):

    ret += '    {0x00}, ' + str(hex(hasher.state[1])) + '}'
    return ret
 
def output_c_literal(hasher):
    return '{0x' + hasher.digest().hex('_').replace('_', ', 0x') + '}'
 
MESSAGE = b'abcdefghbcdefghicdefghijdefghijkefghijklfghijklmghijklmnhijklmno'
