About JWE Inspector
JSON Web Encryption (JWE) is a format for encoding an encrypted payload as a compact token of five parts: header.encryptedKey.iv.ciphertext.tag.
This tool shows the protected header (key and content encryption algorithms) and explains the structure — useful for debugging and understanding JWE tokens.
Full JWE decryption requires the recipient private key and is not performed here for safety; this tool focuses on header/structure inspection. For signed (not encrypted) tokens, use JWS/JWT.
FAQ
Are my data or keys sent to a server?
No. JWE Inspector runs entirely in your browser using the Web Crypto API and client-side libraries. Your data, passwords, and keys never leave your device.
