Descrizione

This is from master branch (same in 1.4-maint):

def blake2b_256(key, data):
    return hashlib.blake2b(key+data, digest_size=32).digest()

It is one of the chunkid hashes borg uses.

The usage there is unusual, the python docs rather suggest:

def blake2b_256(key, data):
    return hashlib.blake2b(data, key=key, digest_size=32).digest()
