My reply (which has been added to for the purposes of this posting) I would strongly urge using the CryptoAPI as specified by MicrosoftenCommunityServer 2008.5 SP2 (Build: 40407.4157)http://msmvps.com/blogs/access/archive/2008/11/18/encryption-and-developers.aspx#1654974Mon, 24 Nov 2008 22:06:52 GMTd67277c4-116b-43f1-b688-e9ef184ea916:1654974Alun Jones<p>The more interesting point here is that if you use CryptoAPI, your solution will benefit from upgrades that Microsoft rolls out to address any issues with their security or encryption.</p> <p>Not that an automatic upgrade would have helped with the Debian / Ubuntu issue, mind you, as that caused problems generating certificates - and once the certificate is generated, no update is going to remove it, because of all the things that would break.</p> <div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=1654974" width="1" height="1">
