Security

4 free tools, ready to use

Small security and encoding utilities for daily work: hash text or files, encode and decode URLs, and validate identifiers — computed on your own device.

URL EncoderMake any text safe to put in a URL. Encode a single query value or path segment, or a whole URL with spaces and non-English characters, and inspect its parts.Open tool →

URL DecoderTurn unreadable links full of %20, %3A and %2F back into plain text. See every query parameter decoded, and get a clear warning when an escape is broken.Open tool →

Hash GeneratorCalculate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text or file at once, create HMACs with a secret key, and check a download against its published checksum.Open tool →

UUID ValidatorPaste one UUID or a whole list to check whether each is valid — with the exact reason when it isn't, plus its version, variant, embedded time and normalized form.Open tool →
