boolean |
verify(java.security.PublicKey key,
java.lang.String sigProvider)
verify that the given public key succesfully handles and confirms the signature associated with this signer. |
boolean |
verify(java.security.cert.X509Certificate cert,
java.lang.String sigProvider)
verify that the given certificate successfully handles and confirms the signature associated with this signer and, if a signingTime attribute is available, that the certificate was valid at the time the signature was generated. |
