hash-wasm is a high-performance cryptographic and non-cryptographic hashing library that leverages hand-optimized WebAssembly binaries to deliver fast hashing capabilities in browsers, Node.js, and other JavaScript environments. The library supports a wide range of algorithms, including MD5, SHA variants, BLAKE, Argon2, bcrypt, and xxHash, making it suitable for applications ranging from security to data processing. By compiling optimized C implementations into WebAssembly, hash-wasm achieves significantly better performance compared to pure JavaScript alternatives while maintaining portability across platforms. It supports both simple one-shot hashing and advanced streaming modes, allowing developers to process large datasets incrementally. The architecture is modular, enabling tree-shaking so that only the required algorithms are included in the final bundle, reducing application size.
