Hash Generator
Compute cryptographic digests of any text using the Web Crypto API - SHA-256, SHA-384, SHA-512 and SHA-1 - without sending anything to a server.
How to use
- Paste or type the text.
- All four hashes are computed instantly.
- Copy the digest you need.
Examples
SHA-256 of "hello"
Input: hello
Output: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824
Frequently asked questions
Which algorithm should I use?
SHA-256 is the common default. Avoid SHA-1 for security-sensitive uses; it is included for legacy checksum compatibility.
Can I hash files?
Not in this version - it hashes text. File hashing may come later.
