The most popular algorithms include HMAC with SHA SHA or SHA HS HS HS . here and a single secret is required for both signing and verifying the authenticity of the token RSASSA PKCS v _ with SHA SHA or SHA RS RS RS . RSASSA PKCS v _ uses asymmetric cryptography which requires a public and private key pair. The public key allows you to verify the authenticity of the token and the private key allows you to sign it ECDSA with SHA SHA or SHA RS RS RS . The situation is analogous to the RSASSA PKCS v _ algorithm.
Appropriate juggling of the signing algorithm has in the past Phone Number List been an attack vector allowing bypassing token verification in selected libraries implementing JWT. You can learn more about these issues from CVE and CVE . A separate document RFC is devoted to the algorithms used by JWS JWE and JWK . Pay particular attention to the value none. This value means that the token is unsigned and therefore its authenticity cannot be verified.
Attempting to pass tokens with a value none is an attack vector against applications that incorrectly handle tokens with that value. If the application treats such tokens as valid it becomes possible to generate any valid token. It clearly indicates the existence of a vulnerability in the infiltrated application. If the token is used for example to determine the user's role it is an open door to escalation of privileges. JSON Web Key JWK JSON Web Key is a data.
