Method Detail

getEncoded

public byte[] getEncoded()

Description copied from interface: Key

Returns the encoded form of this key.

Specified by:

getEncoded in interface java.security.Key

getAllowExport

public boolean getAllowExport()

Description copied from interface: Key

If false, this key's material may not be exported in plaintext; if true, and if the global export flag is true, the key's material may be exported in plaintext.

If plaintext export is not allowed, the key's output methods, such as Key.getEncoded() will throw a KeyExportException.

Returns:

Whether or not this key's material may be exported in plaintext.
