SMIME signed email and VB

Author	Message
Matthias Mer #1 / 2	SMIME signed email and VB Dear all, I need to process digitally signed Emails with VB. So I have to check if a digital signature is valid or not and if the sent message was altered or corrupted during the transmission. Outlook 2000 does this on its user interface but the Object Model does AFAIK not offer the items to check this properties. Is there another chance to control Outlook to get the information? Or do you know a tool or control which can do the validation? Any help is appreciated. Thanks in advance. CU Matze --

Chris Judg #2 / 2	SMIME signed email and VB Matthias, I don't know if you can make Outlook do it for you, but my guess is that if Outlook can verify these signatures then the required CSP (cryptographic service provider) is available under CryptoAPI. If you haven't used CryptoAPI, there will be a learning curve, but the concepts are easy to learn. CryptAPI is for cryptography what ODBC is for databases - a common API to access the myriad of cryptographic algorithms. I have converted a large part of the CryptoAPI header file to VB6 syntax, but it's far from complete. Email me at or knows where to get one, I'd love to hear about it. chris judge Quote: > Dear all, > I need to process digitally signed Emails with VB.
