An incorrect constant for the key length in libcrux-poly1305 caused the standalone MAC function libcrux poly1305::mac to always panic with an out-of-bounds memory access.

Impact

Applications wishing to use libcrux-poly1305 as a standalone MAC would experience panics. The use of libcrux-poly1305 in libcrux-chacha20poly1305 is unaffected.

Mitigation

Starting from version 0.0.5, the correct value is used for the key length constant.
