hash-wasm is a fast hash function library for browsers and Node.js implemented with hand-tuned WebAssembly binaries. It supports a wide range of algorithms including MD5, SHA-1/2/3, Keccak, BLAKE2/3, xxHash, CRC, and key derivation functions like Argon2, bcrypt, scrypt, and PBKDF2.

Use cases

• compute md5 or sha256 checksums of files in the browser
• hash passwords with argon2 or bcrypt in nodejs
• calculate fast non-cryptographic hashes with xxhash for hash tables
• generate crc32 checksums for data integrity checks
• derive keys with pbkdf2 or scrypt in javascript
• compute blake3 hashes faster than pure js implementations
• hash data in web workers without native dependencies

When to choose

• you need hash functions in both browser and Node.js with one library
• pure JavaScript hash implementations are too slow for your workload
• you need many hash algorithms behind a single consistent API
• you want small per-algorithm bundle sizes
• you need password hashing (argon2, bcrypt, scrypt) without native modules

When to avoid

• you need hardware-accelerated hashing via native code (e.g. OpenSSL bindings)
• you only need one hash and a tiny native or built-in option exists (e.g. Node crypto)
• your environment cannot load WebAssembly
• you need streaming hashes over very large files with minimal memory in constrained environments
