Security, Encoding & Cryptographic Utilities
Securing application configurations, encoding tokens, and hashing files are everyday tasks for modern developers. Our browser-native security utilities let you inspect JWT credentials, generate cryptographic hashes (SHA-256, MD5), and encode Base64 tokens entirely in your sandbox with zero server roundtrips.
-
Decode JSON Web Tokens (JWT) in real-time, view headers and payloads, and format token timestamps into human-readable local dates.
-
Decode, inspect, edit, and cryptographically re-sign JSON Web Tokens (JWT) in real-time with signature verification.
-
Generate secure cryptographic checksums including MD5, SHA-1, and SHA-256 instantly in your browser using native Web Crypto APIs.
Frequently Asked Questions
Are my sensitive security keys or JWTs safe here?
Yes, absolutely. All encoding, hashing, and token inspection are performed purely inside your browser. No data ever leaves your machine, preventing credential leaks, security logging, or intermediate eavesdropping.
Can I use these security tools offline?
Yes. Once loaded, all calculations execute client-side. You can completely disconnect from your network, making them safe for sensitive enterprise setups or secure air-gapped workstations.
