I'm looking for an application, which can make cms encryption/decryption, but with the use of the windows certificate store.

I already found out, that openssl can't do it out of the box (just by exporting the cert out from the windows certificate store, and then exporting it to openssl's cert store), and sadly powershell's Protect-CmsMessage doesn't work with elliptic curve (ECC) keys. (as far as I know, I tested it, and it just throws 'Unknown encryption algorithm').

So I need an application which can encrypt/decrypt with an ECC certificate from the windows cert store.
