Synopsis

This interface defines the high-level characteristics of all cryptographic keys. getAlgorithm( ) returns the name of the cryptographic algorithm (such as RSA) used with the key. getFormat( ) return the name of the external encoding (such as X.509) used with the key. getEncoded( ) returns the key as an array of bytes, encoded using the format specified by getFormat( ).
