Developer Tools
Hash Generator (SHA-1/256/384/512)
Generate cryptographic hashes for any text in your browser.
About this tool
Cryptographic hashes turn any input into a fixed-length fingerprint. Developers use them for password storage, file integrity checks, and digital signatures. This tool runs entirely in your browser using the Web Crypto API — your text never leaves your device.
How to use
- Paste your text.
- Click Generate Hashes.
- Copy any of the SHA variants.

- • Quick checksum checks
Tips & best practices
- • Use SHA-256 as the modern default
- • Never use MD5 or SHA-1 for passwords
- • Always salt before hashing passwords
