sha2

SHA-2 cryptographic hash functions — SHA-256, SHA-384, SHA-512.

What it is

sha2 implements the SHA-2 family of hash functions following the RustCrypto Digest trait interface, making it composable with other cryptographic primitives. SHA-224, SHA-256, SHA-384, and SHA-512 are all provided.

Why it is commonly used

Used for content hashing, integrity verification, digital signatures, and certificate fingerprinting. SHA-256 is the most common choice for checksum and integrity use cases in production Rust code.
