no-std base16ct

Pure Rust implementation of Base16 a.k.a hexadecimal (RFC 4648) which avoids any usages of data-dependent branches/LUTs and thereby provides portable "best effort" constant-time operation and embedded-friendly no_std support

RustCrypto: Constant-Time Base16 (hexadecimal)

crate Docs Build Status Apache2/MIT licensed Rust Version Project Chat

Pure Rust implementation of Base16 (RFC 4648).

Implements lower and upper case Base16 variants without data-dependent branches or lookup tables, thereby providing portable "best effort" constant-time operation.

Supports no_std environments and avoids heap allocations in the core API (but also provides optional alloc support for convenience).
