Encrypt/decrypt compatibility with Microsoft Crypto API? [message #173897]

We have a Windows program that we have developed that uses the Microsoft
Crypto API to encrypt/decrypt data using a shared secret from which it
derives a session key.

I now need to be able to access that same data (stored in a database)
from our web site using PHP. I've used mcrypt before, but that doesn't
appear to be a compatible solution. I've done enough research to see
that I might be able to use OpenSSL, but I have not yet been able to
determine whether I'll be able to decrypt data that was encrypted with
the MS Crypto API (as well as the reverse).

I've also looked at the possibility of accessing the MS Crypto API
directly through PHP, but I haven't yet found a good way to do that.

The other option is to write another Windows program that can be called
from PHP, passing stuff on the commandline, and then receive output via
a text file. I'm doing something similar to do some calculations for
something else on the web site already - but it's not very fast.

Any suggestions would be greatly appreciated!

Thanks,
Trevor
