Rust crate for encoding/decoding binary data to/from base64 and hex encodings while avoiding data-dependent branching/table lookups, and therefore providing "best effort" constant-time operation.
Useful for encoding/decoding secret values such as cryptographic keys.
- Rust 1.35+
While this crate takes care to avoid data-dependent branching, that does not actually make it "constant time", which is an architecture-dependent property.
This crate is a "best effort" attempt at providing a constant time encoding library, however it presently provides no guarantees, nor has it been independently audited for security vulnerabilities.
Use at your own risk.
