Hash

BLAKE2

BLAKE2 is a cryptographic hash function specified in RFC 7693.

BLAKE2’s design makes it immune to length-extension attacks, an advantage over the SHA-family of hashes.

python
from cryptography.hazmat.primitives import hashes

digest = hashes.Hash(hashes.BLAKE2b(64))
digest.update(b"Tortuga")
digest.update(b"Gallina")
hash = digest.finalize()

print(hash.hex())

El resultat és el hash de TortugaGallina en hexadecimal:
