Hash, Base64, JWT, HMAC, URL encode/decode — an encoding & decoding toolkit for developers.
- Base64 Encode / Decode Convert text to Base64 and back, with full Unicode (UTF-8) support.
- URL Encode / Decode Percent-encode text for safe use in URLs, or decode %xx sequences back.
- Hash Generator (MD5, SHA-1, SHA-256, SHA-512) Compute MD5, SHA-1, SHA-256, SHA-384 and SHA-512 digests from any text.
- JWT Decoder & Validator Decode a JWT's header and payload, inspect its claims, and verify an HS256 signature.
- HMAC Generator (SHA-1, SHA-256, SHA-512) Compute an HMAC from a message and secret key using SHA-1/256/384/512, as hex or Base64.
