What is a hash?

A hash is the result of a one-way cryptographic function. Original data cannot be recovered from a hash.

Use Cases

Privacy

All hashes are calculated locally in your browser using Web Crypto API. Data is never sent to a server.

Important

MD5 and SHA1 are not recommended for cryptographic purposes. Use SHA256 or higher for security.
