CT-Codecs

A reimplementation of the base64 and hexadecimal codecs from libsodium and libhydrogen in Rust.

• Constant-time for a given length, suitable for cryptographic purposes
• Strict (base64 strings are not malleable)
• Supports padded and unpadded, original and URL-safe base64 variants
• Supports characters to be ignored by the decoder
• Zero dependencies, no_std friendly.

Example usage

use ct_codecs::{Base64UrlSafe, Decoder, Encoder};

let encoded = Base64UrlSafe::encode_to_string(x)?;
let decoded = Base64UrlSafe::decode_to_vec(encoded, None)?;
