Thanks mahesh,<br />

The codeproject link looks like what I need to figure out how to use the CryptEncrypt function.

Hi,<br />
I want to be able to encrypt a CString. Since I am doing some application programming in MFC, I would like to use the CryptEncrypt() function. Can somebody show me how to use this function? The example in MSDN deals with encrpyting a file, but I need to just encrypt a string. <br />
I don't need the encryption to be very complicated, just reasonably secure.<br />
<br />
Thanks.

Encrypting a CString

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

Microsoft Development

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
