RustCrypto/utils

Bytes related utility functions

Set of low-level functions useful for cryptography

Test helpers for cryptographic algorithms

This crate is deprecated. Use explicit impl of `fmt::Debug` instead.

A macro for converting hexadecimal string literals to a byte array at compile time

Crate for mimicking simd crate on stable Rust

Buffer types for block processing of data

DEPRECATED: replaced by the `cpufeatures` crate

Lightweight runtime CPU feature detection for aarch64, loongarch64, and x86/x86_64 targets, with no_std support and support for mobile targets including Android and iOS

Securely clear secrets from memory with a simple trait built on stable Rust primitives which guarantee memory is zeroed using an operation will not be 'optimized away' by the compiler. Uses a portable pure Rust implementation that works everywhere, even WASM!

Iterator over simple binary blob storage

Custom reference types for code generic over in-place and buffer-to-buffer modes of operation.

Custom derive support for zeroize

Compile-time detection heuristics for the optimal word size to use for the target CPU, which in some cases may differ from its address size a.k.a. `target_pointer_width`. Implemented as `macro_rules!`
