# RustCrypto: Signatures [![Project Chat][chat-image]][chat-link] [![dependency status][deps-image]][deps-link]



Support for [digital signatures][1], which provide authentication of data using

public-key cryptography.



All algorithms reside in the separate crates and implemented using traits from

the [`signature`](https://docs.rs/signature/) crate.



Crates are designed so they do not require the standard library (i.e. `no_std`)

and can be easily used for bare-metal or lightweight WebAssembly programming.
