How to interoperate CDSA and Microsoft Crypto API


I need help adding encryption to an existing UDP/ip application. I am using CDSA v2 on VMS 7.3. My co-worker is using the Microsoft Crypto API on windows.

He wants to send me a Microsoft Public Key Blob containing a 1024 bit RSA key.

I want to get a 128 bit RC4 sesson key, encrypt is with his public key and send it back.

Unfortunately I can't figure out how to do this.

Thanks in advance for any help.
