+# 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.
+
+## [API documentation](https://docs.rs/ct-codecs)
+
+## Example usage
+
+```rust
+use ct_codecs::{Base64UrlSafe, Decoder, Encoder};
+
+let encoded = Base64UrlSafe::encode_to_string(x)?;
+let decoded = Base64UrlSafe::decode_to_vec(encoded, None)?;
+```
