Show HN: Rscrypto, pure-Rust crypto with industry leading public benches

Rscrypto is a pure-Rust cryptographic library that provides primitives like hashing, encryption, and password hashing without external C dependencies or OpenSSL, using SIMD and assembly acceleration for performance. The project emphasizes security assurance through rigorous testing including NIST vectors, fuzzing, constant-time verification, and differential testing, while acknowledging that it lacks a third-party security audit. The library offers granular feature flags allowing developers to install only needed cryptographic primitives.
