How to Use Hash Generator

  1. 1

    Choose input type

    Select Text Input to hash text, or File Input to hash a file via drag and drop.

  2. 2

    Select algorithms

    Pick which hash algorithms to compute. Choose from 10 algorithms including MD5, SHA-256, BLAKE3, and more.

  3. 3

    Generate and copy

    Click Generate Hashes to compute all selected algorithms simultaneously via WebAssembly. Copy any hash with one click.

Frequently Asked Questions

10 algorithms: MD5, SHA-1, SHA-256, SHA-512, SHA-3 (256-bit), BLAKE2b, BLAKE3, CRC32, xxHash64, and Keccak-256. All are computed via WebAssembly for maximum speed.

Each hash algorithm runs as a compiled WebAssembly binary, which is significantly faster than pure JavaScript implementations. The WASM modules are loaded on demand and run entirely in your browser.

MD5 is cryptographically broken and should not be used for security purposes. It is still useful for checksums and non-security integrity checks.

No. All hash computation happens locally in your browser via WebAssembly. Nothing is sent to any server.

Yes. File hashing reads the entire file into memory, so it works well for files up to a few hundred MB depending on your device's available RAM.

Compare mode lets you paste two hashes to check if they match. Useful for verifying file integrity after downloads.
