public String getAlgorithm()
public byte[] getEncoded()
public abstract String getFormat()
If the opaque representation of a key (see Key
) can be transformed (see KeyFactory
) into this key specification (or a subclass of it), getFormat
called on the opaque key returns the same value as the getFormat
method of this key specification.
