JWT Decoder
Take a peek inside a JWT header and payload. No token uploads.
Free · Browser-basedGenerate a SHA-256, SHA-384, or SHA-512 fingerprint of your text.
Paste the exact text to hash, including any relevant whitespace.
Choose a SHA algorithm.
Generate and copy the lowercase hexadecimal digest.
Create a SHA-2 digest of UTF-8 text with the Web Crypto API. The same bytes and algorithm always produce the same hexadecimal digest.
This is a plain unsalted digest, not password hashing or HMAC. A trailing newline changes the result. HTTPS or localhost is required.
Hashes are not encodings and have no general decoding operation. Weak inputs can still be guessed by hashing candidates.
No. Use a purpose-built password hashing scheme with an appropriate salt and work factor.
This tool runs in your browser. Your input is not uploaded or saved by Saanvi.
