About this tool
A cryptographic hash turns any input into a fixed-length fingerprint. The same input always yields the same hash, and even a tiny change produces a completely different result. This tool computes SHA-1, SHA-256, SHA-384 and SHA-512 using your browser's built-in Web Crypto API — nothing is uploaded.
FAQ
Do you support MD5?
No — the Web Crypto API doesn't include MD5 because it's cryptographically broken. Use SHA-256 or stronger for security-sensitive work.
Is my input sent anywhere?
No. Hashing runs entirely in your browser via the Web Crypto API.
Which hash should I use?
SHA-256 is the modern default. Use SHA-512 for extra length; avoid SHA-1 for security as it's deprecated.
