Security Tools

Security tools for tokens, hashes and encrypted text. Decode and sign JWTs, generate MD5 and SHA hashes with HMAC, and encrypt text with AES-256-GCM. These are exactly the jobs you should never paste into a random server, so everything here runs on your device only.

JWT Decoder Decode JWT header and payload locally. Hash Generator MD5, SHA-1, SHA-2 hashes + HMAC, for text and files. JWT Signer Sign JSON Web Tokens locally (HS256, HS384, HS512). AES Encrypt / Decrypt Encrypt text with a password (AES-256-GCM), decrypt it back.
