JTIs

JTIs, or JSON Web Tokens (JWTs) with a specific claim, are a type of token used for securely transmitting information between parties as a JSON object. This claim is typically named "jti" and stands for "JWT ID." The jti claim provides a unique identifier for the JWT, which can be used to prevent replay attacks. Each jti value must be assigned in such a way that no two valid tokens will have the same jti value. This uniqueness is crucial for ensuring the security and integrity of the token. The jti claim is optional but recommended for scenarios where token reuse needs to be prevented. When using JTIs, it is important to consider the storage and management of these identifiers to avoid potential performance and security issues.
