SecretKey
Synopsis
This interface represents a secret
key used for symmetric cryptographic algorithms that depend on both
the sender and receiver knowing the same secret.
SecretKey
extends the
java.security.Key
interface, but does not add any
new methods. The interface exists in order to keep secret keys
distinct from the public and private keys used in public-key, or
asymmetric, cryptography. See also
java.security.PublicKey
and
java.security.PrivateKey
.
A secret key is nothing more than
arrays of bytes and does not require a specialized encoding format.
Therefore, an implementation of this interface should return the
format name “RAW” from
getFormat( )
and should return the bytes of the
key from getEncoded( )
. (These two methods are
defined by the java.security.Key
interface that
SecretKey
extends.)
