Frequently asked questions
- Which hash algorithms are available?
- It computes SHA-1, SHA-256, SHA-384 and SHA-512 at the same time using the browser's Web Crypto API, and all four results update as you type.
- Is hashing the same as encryption?
- No. A hash is a one-way fingerprint. You can verify data against a digest, but you can never turn the digest back into the original text.
- Does my text leave the browser?
- No. Hashing is performed locally with the Web Crypto API, so passwords, API keys and other sensitive strings stay on your device.
- Can I hash a file instead of text?
- Not with this tool. It hashes only what you type or paste into the text field.
