SipHash_2_4

✓ from siphash import SipHash_2_4

Correct, though SipHash_2_4 is a class; there is also SipHash_1_3.

Setup key and message, then call instance to get 64-bit hash.

from siphash import SipHash_2_4 key = b'\x00' * 16 # 128-bit key msg = b'hello' siphash = SipHash_2_4(key) digest = siphash(msg) print(digest.hex()) # 64-bit digest

Debug

Known issues

gotchaKey must be exactly 16 bytes; any other length raises ValueError.

fix

Ensure key length is 16.

affects: 0.0.1

gotchaSipHash_2_4 and SipHash_1_3 are the only variants; no 8-round or 4-round versions.

fix

Use SipHash_2_4 for default security.

affects: 0.0.1

gotchaInput message must be bytes; passing str will cause TypeError.

fix

Encode strings before hashing: msg.encode('utf-8')

affects: 0.0.1

Errors

Common errors & fixes

TypeError: a bytes-like object is required, not 'str'

Message passed as string instead of bytes.

fix

Use msg = 'hello'.encode('utf-8')

ValueError: Key must be exactly 16 bytes long

Key length is not 16 bytes.

fix

Ensure key is 16 bytes: key = b'sixteenbyteslong'
