Raw Generic Hash (Blake2b) Functions¶
The nacl library comes with blake hashing libraries.
More information on Blake can be found here: https://blake2.net
The blake2b hashing algorithm is a keyed hashing algorithm, which allows for a key to be associated with a hash. Blake can be executed with or without a key.
With a key (they key can should be between 16 and 64 bytes):
import libnacl msg = 'Is there someone else up there we could talk to?' key = libnacl.randombytes(32) h_msg = libnacl.crypto_generichash(msg, key)
Without a key:
import libnacl msg = 'Is there someone else up there we could talk to?' h_msg = libnacl.crypto_generichash(msg)
