subtle-encoding 0.3.5

Encoders and decoders for common data encodings (base64, bech32, hex) which avoid data-dependent branching/table lookups and therefore provide "best effort" constant time. Useful for encoding/decoding secret values such as cryptographic keys.

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.

## Security Notice

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.
