I have an application that produces a periodic XML file that is sent to a Lotus Domino server for import into their system. They have asked that we help automate this process by encrypting the XML file before sending.

They have proposed that they would "generate an assymetrical key pair, then Base64 encode the public key and e-mail it" to us. They then propose that we could "use that public key to encrypt
the XML file and send it" back to a specified location.

I'm trying to determine what technology is needed on my end to perform this encryption. I note that the MS Crypto API has the ability to perform two types of encryption using a key -- session block or session stream.

Does anyone know whether either of these API functions would produce the encryption that could be used by Domino/Java at the recieving end? Also, is there anything further I need to have specified by them?

Thanks,
