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  = '    {{0x' + hasher.state[0].hex('_', 4).replace('_', ', 0x') + '},\n'
    ret += '    {0x00}, ' + str(hex(hasher.state[1])) + '}'
    return ret
 
def output_c_literal(hasher):
    return '{0x' + hasher.digest().hex('_').replace('_', ', 0x') + '}'
 
MESSAGE = b'abcdefghbcdefghicdefghijdefghijkefghijklfghijklmghijklmnhijklmno'
assert(len(MESSAGE) == 64)
BYTE_BOUNDARIES = [(2**b)//len(MESSAGE) - 1 for b in range(20, 34)]
 
midstates = []

hasher = sha256()
for i in range(BYTE_BOUNDARIES[-1] + 1):
    if i in BYTE_BOUNDARIES:
        midstates.append(midstate_c_definition(hasher))
        hasher_copy = copy(hasher)
        hasher_copy.update(MESSAGE)

    hasher.update(MESSAGE)
