# 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

```rust

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

let encoded = Base64UrlSafe::encode_to_string(x)?;

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

```
