Hash Generator (SHA-1, SHA-256, SHA-512) — FAQ
For most purposes, use SHA-256 or SHA-512. SHA-1 is considered weak for security applications and is only recommended for legacy compatibility.
No. Hashing is one-way: you cannot recover the original input from a hash. Encryption is reversible with a key. They serve different purposes.
Yes. Upload any file and the tool computes its hash locally using the browser's File and Web Crypto APIs.
That is the point of a hash — it is deterministic. The same input always yields the same fingerprint, which is how integrity checks and fingerprinting work.
