RustCrypto: Constant-Time Base32
Pure Rust implementation of Base32 (RFC 4648).
Implements lower and upper case Base32 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).
