Password-Hasher-Puzzle

This is a value I take from the pidev-server log:

from argon2 import PasswordHasher
ph = PasswordHasher()

print("Test as string")
hash='$argon2i$v=19$m=102400,t=2,p=8$NSYEwHiP0VoLQQgBAKD0Pg$Tg493ikpeaglkoFmG5AdYw'
print("check: %s of type:%s" % (ph.check_needs_rehash(hash), type(hash)))

print("Test as bytes")
hash=b'$argon2i$v=19$m=102400,t=2,p=8$NSYEwHiP0VoLQQgBAKD0Pg$Tg493ikpeaglkoFmG5AdYw'
print("check: %s of type:%s" % (ph.check_needs_rehash(hash), type(hash)))

Result:
Test as string
check: True of type:<class 'str'>
Test as bytes
Traceback (most recent call last):
