Examples of java.security.PublicKey

java.security.PublicKey

A public key. This interface contains no methods or constants. It merely serves to group (and provide type safety for) all public key interfaces. Note: The specialized public key interfaces extend this interface. See, for example, the DSAPublicKey interface in java.security.interfaces. @see Key @see PrivateKey @see Certificate @see Signature#initVerify @see java.security.interfaces.DSAPublicKey @see java.security.interfaces.RSAPublicKey @version 1.33 05/11/17
