oracle.security.crypto.core.RSAKey
oracle.security.crypto.core.RSAPublicKey
public class RSAPublicKey
An RSA public key.
RSA public keys are output in X.509 SubjectPublicKeyInfo format, and this is also the preferred format for input. However, for backwards compatibility reasons, the PKCS #1 RSAPublicKey format is recognized for input as well.
