The neat thing about JWT is that there are no secrets to scan for. Your secret material ideally lives inside an HSM and never leaves. Scanning for these private keys is a waste of energy if they were generated inside the secure context.
- vjay15 7mo agoIdeally API key shouldn't contain anything regarding the account or any info right? it's meant to be an opaque string, is what I found in most of the other articles I read. Please do let me know if I am wrong about this assumption
- miningape 7mo agoLook at the JWT standard, it usually contains things like claims, roles, user ids, etc.
- ijustlovemath 7mo agoJWT operates on a different principle; the user's private key (API key) never leaves the user's device. Instead, the stated "role" and other JSON data are signed with the servers pubkey, then verified by the server using its master key, granting the permissions that role allows.
- agwa 7mo agoBut JWTs are usually used as bearer tokens when doing API authentication. Those are definitely secrets that need to be scanned for. Or are you suggesting that the API requests are signed with a private key stored in an HSM, and the JWT certifies the public key? Is that common?
- mattacular 7mo agoThat's how JWT is designed to work

The thing that certifies the public key is called a JWK. https://datatracker.ietf.org/doc/html/rfc7517 https://datatracker.ietf.org/doc/html/rfc7517 This is typically hosted at a special URL that enables seamless key rotation and discovery. https://auth0.com/docs/secure/tokens/json-web-tokens/json-web-key-sets https://auth0.com/docs/secure/tokens/json-web-tokens/json-we...
