generate MD5, SHA-1, SHA-256, and SHA-512 hashes for text or files. all hashes update in real-time as you type.
Hash Generator computes MD5, SHA-1, SHA-256, and SHA-512 hashes for any text or file. Use it to verify file integrity, generate checksums, or create hashed representations of passwords and data.
All four hash algorithms run simultaneously, so you can compare outputs side by side. Type or paste text and see the hashes update in real time. For files, upload and get all four checksums instantly.
The tool runs entirely in your browser using the Web Crypto API. Your text and files are never sent to any server.
