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.
