I've done some CAPI/OpenSSL interop. It is just a case of reading the relevant documents and converting between the key formats. CryptoAPI generally uses little endian format while OpenSSL uses BIGNUMs which can be converted to big endian format and from that to little endian. Steve. -- Dr Stephen N. Henson.
