JWT Decoder & Hash Generator
JSON Web Tokens (JWT) are used for secure information transmission between parties. Our JWT decoder lets you inspect the header and payload of any JWT token without verification. Perfect for debugging authentication issues and understanding token contents.
The hash generator creates cryptographic hashes using SHA-1, SHA-256, or SHA-512 algorithms. Use it for data integrity verification, creating checksums, or generating unique identifiers. All operations are performed securely in your browser.

About JWT
JSON Web Tokens (JWT) are an open standard for securely transmitting information between parties as a JSON object. They consist of three parts: header, payload, and signature.
About Hashing
Hash functions convert data into a fixed-size string of characters. They're one-way functions used for data integrity, passwords, and digital signatures.
