Hash Generator (SHA)
Developer
Compute cryptographic hashes of any text using the browser's built-in Web Crypto API. See SHA-1, SHA-256, SHA-384, and SHA-512 at once, as hex. Useful for checksums, integrity checks, and fingerprints. Everything runs locally — your input is never uploaded.

How to use
- Type or paste your text into the input.
- All hashes are computed instantly.
- Copy any hash with its Copy button.
- Compare against an expected checksum to verify integrity.
Frequently asked questions
- Is MD5 supported?
- No. The Web Crypto API doesn't include MD5; this tool offers the secure SHA family instead.
- Are hashes computed locally?
- Yes. Hashing uses your browser's Web Crypto API; nothing is sent to a server.
- Is the input encoded as UTF-8?
- Yes, text is encoded as UTF-8 before hashing, so results match standard tools.
- Can I hash a file?
- This tool hashes text. File hashing may be added as a separate tool later.
