Hash Generator
Generate cryptographic hashes (SHA-1, SHA-256, SHA-384, SHA-512) from any text using your browser’s built-in Web Crypto. Your input never leaves your device.

About the hash generator
A hash is a fixed-length fingerprint of your input — change one character and the whole hash changes. Hashes are used to verify file integrity, store passwords safely (with salting) and compare data without revealing it. This tool computes SHA-1, SHA-256, SHA-384 and SHA-512 with the browser's native Web Crypto, so your text is never uploaded.
Frequently asked questions
Which hash algorithms are supported?
SHA-1, SHA-256, SHA-384 and SHA-512, computed with your browser’s built-in Web Crypto API.
Why is there no MD5?
Browsers’ native crypto does not include MD5 (it is considered broken). The SHA family here is computed securely without any external library.
Is my input sent anywhere?
No. Hashing happens entirely in your browser, so your text never leaves your device.
