java.lang.Object com.nimbusds.jose.crypto.RSASSAVerifier
@ThreadSafe public class RSASSAVerifier
RSA Signature-Scheme-with-Appendix (RSASSA) verifier of
JWS objects
. This class is thread-safe.
Supports the following JSON Web Algorithms (JWAs):
Accepts all reserved JWS header parameters
. Modify the header filter
properties to restrict the acceptable JWS algorithms and
header parameters, or to allow custom JWS header parameters.
