Rust is the best language so far to replace today's most used crypto libraries: OpenSSL, BoringSSL and libsodium.

C libraries often contain a lof of assembly code making them really fast, but potentially unsafe.
pure-Rust libraries benefit from Rust strong typing and generally offer a better API, compile for all platforms including WebAssembly.

It's important to note that pure-Rust libraries might be slightly slower than C and assembly wrappers, but still fast enough for most use cases.

• aws-lc-rs is a cryptograhy create
• libcrux is a Rust wrapper for formally verified C, Assembly and Rust code.
• ring is focused on the implementation, testing, and optimization of a core set of cryptographic operations exposed via an easy-to-use (and hard-to-misuse)
• boring is a safe wrapper around google's boringssl
• dalek-cryptography is a Github organization about pure-Rust elliptic curve cryptography, used by Signal and Diem
• graviola is promising because it's faster than other projects, but not mature enough yet.

In short, RustCrypto to get pure-Rust implenentations, or aws-lc-rs for linux-servers and best perforamances with FIPS certification.
