In the CNG SDK, creation of a custom asymmetric algorithm is provided. However, I would like to create an asymmetric encryption algorithm instead. Are there any available samples? Specifically, can anyone guide me as to the creation of the interface for BCRYPT_CIPHER_FUNCTION_TABLE/NCRYPT_CIPHER_FUNCTION_TABLE to register the asymmetric algo? Thanks.

For better assistance try the Windows SDK Forum instead:http://social.msdn.microsoft.com/Forums/en-US/windowssdk/threadsDiscuss Windows Vista SDK Documentation, Samples and Tools.Hope this helps, Vincenzo Di Russo - Microsoft MVP Windows Internet Explorer, Windows Desktop Experience & Security - Since 2003. ~~~ My MVP Profile: https://mvp.support.microsoft.com/profile/Vincenzo
