Questions worth answering upfront.

No. Hashes are computed entirely in your browser using the Web Crypto API. Nothing you enter is uploaded or stored.

MD5, SHA-1, SHA-256 and SHA-512 are supported. SHA hashes use the browser's native Web Crypto API.

No. MD5 and SHA-1 are broken for security purposes and should only be used for checksums or non-security use cases. Use SHA-256 or SHA-512 for anything security-related.

No. Hashing is one-way by design. This tool generates hashes; it cannot recover the original input from a hash.
