Security Tools
Hash, encrypt, and analyze security data. All tools run entirely in your browser — nothing is uploaded, nothing is stored.
Security tools help developers implement authentication, encryption, and data integrity without exposing sensitive information. JWT decoders inspect token headers, payloads, and signatures for debugging authentication flows. Hash generators compute MD5, SHA-1, SHA-256, and SHA-512 digests for file integrity verification and password hashing. Password generators create strong, unique credentials resistant to brute force and dictionary attacks. JWT expiration checkers validate token lifetimes and claims for secure session management. Every security tool runs 100% client-side — your secrets, tokens, and passwords never reach any server.
JWT Decoder
Decode and inspect JWT tokens — view header, payload, and signature information instantly.
Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text input. Fast, secure, and browser-based.
JWT Expiration Checker
Check when a JWT token expires. Decode JWT headers and payloads, inspect exp, iat, and other claims in real-time.
