Crate base32ct

source ·
Expand description

Pure Rust implementation of Base32 (RFC 4648).

Implements Base32 variants without data-dependent branches or lookup tables, thereby providing portable “best effort” constant-time operation. Not constant-time with respect to message length (only data).

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

Adapted from: https://github.com/paragonie/constant_time_encoding/blob/master/src/Base32.php
