Interface SecretKey
- All Known Implementing Classes:
- SecretKeySpec
- public abstract interface SecretKey
- extends java.security.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.)
