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.

• JWT Decoder

  Decode JSON Web Tokens, view headers and payloads, and convert timestamps into local dates. All processing runs in your browser without any server uploads.

• JWT Inspector

  Decode, inspect, edit, and cryptographically re-sign JSON Web Tokens with signature verification. The tool runs in your browser without any server uploads.

• Cryptographic Hash Generator

  Generate secure cryptographic checksums (MD5, SHA-1, SHA-256, SHA-512), DES encryptions, and RSA-2048 signatures in real-time directly in your browser, with no uploads.

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.
