Hash Generator
————Compute MD5, SHA-1, SHA-256, and SHA-512 hashes for text or a file, all at once. This is commonly used to verify file integrity — paste a published checksum into the compare field to instantly check whether it matches. Hashing runs entirely in your browser via the Web Crypto API; nothing is uploaded.
Frequently asked questions
Is MD5 or SHA-1 safe to use for security?
No — both are cryptographically broken and shouldn't be used for passwords, signatures, or anything security-sensitive. They're included here because they're still widely used for non-security purposes like file integrity checks and cache keys.
How do I verify a downloaded file's checksum?
Switch to File input, drop the downloaded file in, then paste the checksum published by the file's source into the compare field. A match confirms the file wasn't corrupted or tampered with in transit.
Does the compare field care about which algorithm I used?
No — it checks the pasted value against all four computed hashes at once, so you don't need to know which algorithm the published checksum uses.
