    Hi EB,

    I am creating a simple chat application for academic purposes. This
    application makes use of Crypto APIs.

    Now the client side of the chat application exports its public key in a
    buffer by calling the API CryptExportPublicKeyInfo (.., AT_KEYEXCHANGE, ...,
    ... ) and then sends this buffer to the server.

    The server does a receive and tries to import this buffer by calling the API
    CryptImportPublicKeyInfo. However the CryptImportPublicKeyInfo fails with
    error code 0x8009310b - "ASN1 bad tag value met."

    I guess the reason why this API fails is because there are references to
    pointers in the CERT_PUBLIC_KEY_INFO structure which do not get transmitted.

    How can I make my chat application work.

    Thanks & Regards,
    Nilesh Padbidri.
