Encrypt 

This function encrypts a data block. It trashes the original data.  

 

ExportKey 

This is the overview for the ExportKey method overload. 

 

FreeBuffer 

FreeBuffer frees buffer returned by previous calls to ExportKey .  

 

Generate 

Randomly generates a key  

 

GenerateContainerKey 

Randomly generates a public/private key pair and stores it in the key container of the specified CSP. The new key replaces the old key (if existing) in the container. Thus, this constructor is generally used in the following way:  

 

GetExportKeyLength 

GetExportKeyLength can be used to determine the length of the export blob for subsequent calls to ExportKey .  

 

GetKeyParam 

This function can be used to retrieve certain parameters of the key. It is mostly for internal use. See http://msdn2.microsoft.com/en-us/library/aa379949.aspx for more information. 

 

GetUserKey
