Package javax.crypto.interfaces

package javax.crypto.interfaces

Provides interfaces for Diffie-Hellman keys as defined in RSA Laboratories' PKCS #3.

Note that these interfaces are intended only for key implementations whose key material is accessible and available. These interfaces are not intended for key implementations whose key material resides in inaccessible, protected storage (such as in a hardware device).

For more developer information on how to use these interfaces, including information on how to design Key classes for hardware devices, please refer to the cryptographic provider developer guide:

How to Implement a Provider in the Java Cryptography Architecture
