lib1305-1 - 0~20250415-1 main

lib1305 is a microlibrary for the Poly1305 one-time authenticator.
.
lib1305 has a very simple stateless API based on the SUPERCOP API,
with wire-format inputs and outputs, providing a function poly1305 to
generate an authenticator and a function poly1305_verify to verify an
authenticator.
.
Internally, lib1305 includes implementations designed to work
portably across CPUs, and implementations designed for higher
performance on Intel/AMD CPUs with BMI2 instructions. lib1305
includes automatic run-time selection of implementations.
.
lib1305 is intended to be called by larger multi-function libraries
(such as traditional cryptographic libraries), including libraries in
other languages via FFI. The idea is that lib1305 takes
responsibility for the details of Poly1305 computation, including
optimization, timing-attack protection, and (planned) verification,
freeing up the calling libraries to concentrate on
application-specific needs such as protocol integration. Applications
can also call lib1305 directly.
