Asymmetric Cryptography in JWT

Asymmetric cryptography plays a significant role in the security of JSON Web Tokens (JWTs), particularly in the context of signing and verifying tokens.

Public and Private Keys:

• Private Key: Used by the issuer (authentication server) to sign the JWT. This key must be kept secure and private.
• Public Key: Used by the resource server to verify the signature of the JWT, ensuring that the token has not been tampered with and is valid.
