[![Latest Version](https://img.shields.io/crates/v/const_time_enc.svg)](https://crates.io/crates/const_time_enc)

WARNING
-------

As per the terms of the [license](LICENSE), no guarantee of correctness,
fitness for use, or acceptance of liability is made. I am not a professional
cryptographer and I nor anyone else have audited this code. All use is strictly
at your own risk.

The performance will already be significantly worse than any lookup-based
hex/base64 encoding, but be aware that since this library does not have or
intend to have unsafe code, it may not be suitably performant for your usecase.
