Flow
- Choose a mode such as bcrypt, JWT, JWK, UUIDv7, or WebAuthn options.
- Provide input/secret/salt values depending on mode.
- Generate output and copy results for local testing.
Example
Worked example: generate JWT and verify signature
- 1 Switch to JWT generator mode and provide a JSON payload.
- 2 Generate a signed token with your secret.
- 3 Switch to JWT sign/verify mode and validate the token.
You get a signed JWT plus a verification report showing signature validity and decoded payload.
How
- Choose a mode such as bcrypt, JWT, JWK, UUIDv7, or WebAuthn options.
- Provide input/secret/salt values depending on mode.
- Generate output and copy results for local testing.
Avoid
- Using development-generated keys or secrets directly in production.
- Choosing low-entropy secrets for signing or KDF workflows.
- Pasting malformed JSON payloads into JWT/JWK conversion modes.
FAQ
Does this support bcrypt, argon2, and scrypt?
Yes. The tool includes bcrypt, argon2id, scrypt, PBKDF2, and modern hash modes such as SHA3 and BLAKE.
Can it generate JWT and JWK output?
Yes. JWT signing/verification and JWK generation/conversion modes are built in.
Is everything processed locally?
Yes. Generation is performed in-browser for privacy-first workflows.
