Hello,
I want to generate a S/MIME mail.
For example :

MIME-Version: 1.0
X-Mailer: Internet Mail Service (5.5.2653.19)
Content-Type: multipart/signed;
        protocol="application/x-pkcs7-signature";
        micalg=SHA1;
        boundary="----=_NextPart_000_00F7_01C0A0B3.B180EAE0"
X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4133.2400

This is a multi-part message in MIME format.


BODY

I succeed to generate the digital Sign (PKCS7), but when I want to verify
the mail to OE 5, I see the signed mail damaged (I could read, but I have
security problem with this mail).

I use this CryptoAPI function :

CryptSignMessage(
    &SigParams,            // Signature parameters
    TRUE,                  // Not detached
    1,                     // Number of messages
    MessageArray,          // Messages to be signed
    MessageSizeArray,      // Size of messages
    NULL,                  // Buffer for signed message
    &cbSignedMessageBlob)) // Size of buffer

Can You help me ?

        RICHARD.
