What is Jwt Rs256 Verifier

The RS256 JWT Verifier validates RSA-SHA256 signed JSON Web Tokens using the provided public key. It verifies the cryptographic signature to ensure the token was signed by the corresponding private key, which only the trusted authority possesses. This asymmetric verification is used in distributed systems where multiple services need to verify tokens without having access to the signing key.
