What is a SHA hash?
A hash generator turns any text into a fixed-length fingerprint. NMSnabbit creates SHA-1, SHA-256, SHA-384 and SHA-512 hashes using the browser built-in Web Crypto API — SHA-256, for example, always produces a 64-character hexadecimal string. Hashing runs locally, so the text you hash never leaves your device.
How to use the Hash Generator
- 1 Type or paste the text you want to hash.
- 2 Choose an algorithm: SHA-1, SHA-256, SHA-384 or SHA-512.
- 3 The hexadecimal hash is generated instantly.
- 4 Copy the hash digest.
What you can use it for
- Verifying data integrity with checksums.
- Generating fingerprints for cache keys.
- Comparing values without storing the original.
- Learning how cryptographic hashing works.
Frequently asked questions
Which hash algorithms are supported?
SHA-1, SHA-256, SHA-384 and SHA-512, all provided by the browser built-in Web Crypto API for correct, fast results.
Is MD5 available?
No. The Web Crypto API does not include MD5 because it is cryptographically broken. SHA-256 is recommended for new uses.
Are my inputs sent anywhere?
No. Hashes are computed locally in your browser, so the text you hash never leaves your device.
Can I hash files?
This tool hashes text. For now, paste the content you want to digest; file hashing may be added later.
