Outline of CryptoAPI Registry Usage

CryptoAPI uses the system Registry to store a database of the CSPs that have been installed on the computer. Both the machine default providers and the user default providers are also recorded here.

Warning This section is included for informational purposes only. The details of CryptoAPI's Registry usage may change at any time. Under no circumstances should an application read from or alter the Registry directly.

The following is a partial outline of the portions of the system Registry used by CryptoAPI. Some sample entries are also shown.

Entries under the HKEY_LOCAL_MACHINE\...\Provider key contain information about all the CSPs that have been installed on the computer. These entries are created by the Setup program used to install a new CSP. Note that these entries are organized under subkeys whose names indicate the provider name.

Entries under the HKEY_LOCAL_MACHINE\...\Provider Types key contain the name of the machine default CSP for each provider type. These entries are also created by the Setup program used to install a new CSP. Note that these entries are organized under subkeys whose names indicate the provider type (in decimal format).

Entries under the HKEY_CURRENT_USER\...\Providers key contain the name of the current user default CSP for each provider type. These entries are created/modified by the CryptSetProvider function. Note that these entries are also organized under subkeys whose names indicate the provider type.

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More »
