All-in-One Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 for any text. Runs fully in your browser. No uploads, no storage.
Note: Hashing is one-way. Use SHA-256/SHA-512 for modern security. MD5/SHA-1 are for legacy checksums only.
What is a hash?
A hash is a fixed-length fingerprint of your text. If the text changes even slightly, the hash changes completely.
Which hash should you use?
Use SHA-256 as the default. Use SHA-512 if you want a longer output. Avoid MD5/SHA-1 for password security.
Is this tool safe?
Yes. Everything runs inside your browser. Your text is not uploaded or stored on the server.
