Examples of java.security.Key

Keys are generally obtained through key generators, certificates, or various Identity classes used to manage keys. Keys may also be obtained from key specifications (transparent representations of the underlying key material) through the use of a key factory (see {@link KeyFactory}).

A Key should use KeyRep as its serialized representation. Note that a serialized Key may contain sensitive information which should not be exposed in untrusted environments. See the Security Appendix of the Serialization Specification for more information. @see PublicKey @see PrivateKey @see KeyPair @see KeyPairGenerator @see KeyFactory @see KeyRep @see java.security.spec.KeySpec @see Identity @see Signer @version 1.57 06/04/21 @author Benjamin Renaud
