JWA implementation (supports all JWS algorithms)

Node.js object hash library with properties/arrays sorting to provide constant hashes

SHA1 wrapper for browsers that prefers `window.crypto.subtle`.

Stable JS value hash.

Implementation of JSON Web Signatures

Lightning fast hash functions for browsers and Node.js using hand-tuned WebAssembly binaries (MD4, MD5, SHA-1, SHA-2, SHA-3, Keccak, BLAKE2, BLAKE3, PBKDF2, Argon2, bcrypt, scrypt, Adler-32, CRC32, CRC32C, RIPEMD-160, HMAC, xxHash, SM3, Whirlpool)

A MurmurHash2 implementation

Pure Javascript implementation of the BLAKE2b and BLAKE2s hash functions

An incremental implementation of MurmurHash3

Stable JS value hash.

abstract base class for hash-streams

fast 64 bit string hashing function

The `package-deps-hash` library generates a JSON object containing the git hashes of all files used to produce a given package. This is useful for scenarios where you want to define a "change receipt" file to be published with a package. The [Rush](http

A pure JS implementation SHA256.

Just enough code to calculate the IPFS hash for some data

SHA256 wrapper for browsers that prefers `window.crypto.subtle` but will fall back to a pure JS implementation in @aws-crypto/sha256-js to provide a consistent interface for SHA256.

Hashing made simple. Get the hash of a buffer/string/stream/file.
