crypto_generichash ValueError

markuman commented 2 years ago

# crypto_generichash(m, k=b'', outlen=crypto_generichash_BYTES)
genericHash = pysodium.crypto_generichash(
    m=_password + passwordSalt,
    k=bytes(genericHashKey, 'utf-8'),
    outlen=pysodium.crypto_generichash_BYTES_MAX
)

results in

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

It looks like the k was wrong

    k=bytes(bytearray.fromhex(genericHashKey)),
