Hash Generator
Generate cryptographic hashes from any text — MD5, SHA-1, SHA-256, SHA-384, and SHA-512 — all at once. Useful for checksums, cache keys, and verifying file integrity. SHA hashes use your browser's built-in Web Crypto, and everything runs locally, so your input never leaves your device.
- Free — no sign-up
- Private — runs in your browser
- Instant results
How to use the Hash Generator
- 1Enter your text. Type or paste the text you want to hash.
- 2See every hash. MD5 and the SHA family are computed instantly as you type.
- 3Copy a hash. Use the copy button next to the algorithm you need.
Frequently asked questions
What is a hash?
A hash is a fixed-length fingerprint of your input. The same input always produces the same hash, but you can't reverse a hash back into the original text.
Are MD5 and SHA-1 safe to use?
MD5 and SHA-1 are fine for checksums and non-security uses, but they're considered broken for security-critical purposes. Use SHA-256 or stronger when integrity against attackers matters.
Is my text sent to a server?
No. Hashing runs entirely in your browser, so the text you enter never leaves your device.
