Hash Generator (SHA)
Produce a cryptographic hash of any text using the Web Crypto API. Useful for checksums, fingerprints and verifying data integrity.
How to use hash generator (sha)
- Enter your text
Paste or type the content you want to fingerprint.
- Choose an algorithm
Pick SHA-256 for general use, or SHA-512 for a longer digest.
- Generate the hash
Click Generate and copy the hex digest for storage or comparison.
Features
Hashing uses the browser's native, audited crypto implementation.
SHA-1, SHA-256, SHA-384 and SHA-512 in one place.
Your text is hashed locally and never sent anywhere.
Frequently asked questions
Can I reverse a hash back to text?
No. Cryptographic hashes are one-way by design — you can only compare hashes, not undo them.
Why is SHA-1 marked as older?
SHA-1 is considered weak for security use. It's fine for non-security checksums but prefer SHA-256 or better for anything sensitive.
Is MD5 available?
No. MD5 is broken for security purposes, so this tool focuses on the SHA family provided by Web Crypto.
