Interface SecretKey
- All Superinterfaces:
- Key, Serializable
- All Known Subinterfaces:
- PBEKey
- All Known Implementing Classes:
- KerberosKey, SecretKeySpec
public interface SecretKey - extends Key
A secret (symmetric) key.
This interface contains no methods or constants.
Its only purpose is to group (and provide type safety for) secret keys.
Provider implementations of this interface must overwrite the
equals and hashCode methods inherited from
java.lang.Object , so that secret keys are compared based on
their underlying key material and not based on reference.
Keys that implement this interface return the string RAW
as their encoding format (see getFormat ), and return the
raw key bytes as the result of a getEncoded method call. (The
getFormat and getEncoded methods are inherited
from the java.security.Key parent interface.)
