Subinterfaces of Key in javacard.security

interface	AESKey AESKey contains a 16/24/32 byte key for AES computations based on the Rijndael algorithm.
interface	DESKey DESKey contains an 8/16/24-byte key for single/2 key triple DES/3 key triple DES operations.
interface	DSAPrivateKey The DSAPrivateKey interface is used to sign data using the DSA algorithm.
interface	DSAPublicKey The DSAPublicKey interface is used to verify signatures on signed data using the DSA algorithm.
interface	ECPrivateKey The ECPrivateKey interface is used to generate signatures on data using the ECDSA (Elliptic Curve Digital Signature Algorithm) and to generate shared secrets using the ECDH (Elliptic Curve Diffie-Hellman) algorithm.
interface	ECPublicKey The ECPublicKey interface is used to verify signatures on signed data using the ECDSA algorithm and to generate shared secrets using the ECDH algorithm.
