Examples of java.security.PrivateKey

java.security.PrivateKey

A private key. This interface contains no methods or constants. It merely serves to group (and provide type safety for) all private key interfaces. Note: The specialized private key interfaces extend this interface. See, for example, the DSAPrivateKey interface in java.security.interfaces. @see Key @see PublicKey @see Certificate @see Signature#initVerify @see java.security.interfaces.DSAPrivateKey @see java.security.interfaces.RSAPrivateKey @see java.security.interfaces.RSAPrivateCrtKey @version 1.30 05/11/17 @author Benjamin Renaud @author Josh Bloch
