## Package javax.crypto.interfaces Description

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 these cryptographic provider developer guides:

- How to Implement a Provider for the JavaTM Cryptography Architecture
- How to Implement a Provider for the JavaTM Cryptography Extension

## Package Specification

- PKCS #3: Diffie-Hellman Key-Agreement Standard, Version 1.4, November 1993.
