A collection of cryptographic hash function implementations written in pure Rust, organized as separate crates built on the digest crate's traits. It supports a wide range of algorithms including SHA-2, SHA-3, BLAKE2, MD5, and GOST, and is no_std capable for bare-metal and WebAssembly use.

Use cases

• compute sha256 hashes in rust
• blake2 hashing library for rust
• verify file checksums with sha3
• hash data in a no_std embedded project
• use md5 for legacy compatibility in rust
• wasm-compatible cryptographic hashing

When to choose

• you need cryptographic hash functions in Rust with pure-Rust, no_std support
• you need broad algorithm coverage including legacy hashes like MD5 or GOST
• you want crates built on a common digest trait for interoperability

When to avoid

• you need a general-purpose non-cryptographic hasher like xxHash for speed
• you need MACs, signatures, or encryption rather than plain hashing
• you need hash functions in a language other than Rust
