About this tool
A hash is a fixed-length fingerprint of your data, produced by a one-way function so the original text cannot be recovered. This generator computes SHA-1, SHA-256 and SHA-512 hashes right in your browser using the native Web Crypto API. Hashes are widely used for verifying file integrity, storing password fingerprints and generating checksums.
How to use
- 1Enter or paste your text.
- 2Choose the hash algorithm.
- 3Copy the generated hash.
Benefits
- SHA-1, SHA-256 and SHA-512.
- Uses the secure Web Crypto API.
- Runs privately in your browser.
Frequently asked questions
Can I reverse a hash?+
No. Hashing is one-way by design; you cannot recover the original text from the hash.
Which algorithm should I use?+
SHA-256 is the modern default. Avoid SHA-1 for security-critical uses as it is considered weak.
