Hash Generator
Generate MD5, SHA-1, SHA-2 and SHA-3 hashes from any text.
--------Hashes are computed in your browser. MD5 and SHA-1 are not secure for passwords or signatures; prefer SHA-256 or SHA-512 for security-sensitive use.
100% private - runs entirely in your browser.
Your input, keys and passwords are never uploaded. Want proof? Load this page, then turn off your internet - the tool still works. For an exact check, open your browser's DevTools Network tab and confirm no data is sent when you use it.
About the Hash Generator
A hash turns any text into a fixed-length fingerprint. The same input always produces the same hash, which makes hashes useful for checksums, cache keys and comparing data.
This tool generates MD5, SHA-1, the SHA-2 family (SHA-224, SHA-256, SHA-384, SHA-512) and SHA-3 (SHA3-256, SHA3-512) all at once, so you can grab whichever algorithm you need.
All hashing happens on your device, so the text you enter is never uploaded.

Examples
hello2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824The same input always produces the same 64-character SHA-256 hash.
hello5d41402abc4b2a76b9719d911017c592MD5 gives a 32-character hash, fine for checksums but not for security.
Frequently asked questions
- Which hash should I use?
- For security-sensitive work use SHA-256 or SHA-512. MD5 and SHA-1 are fine for quick checksums but are considered broken for security purposes.
- Can I reverse a hash back to the text?
- No. Hashing is one-way by design. This tool only generates hashes, it cannot decode them.
- Is my text uploaded anywhere?
- No. Hashing happens entirely in your browser, so the text you enter never leaves your device.
