Any help with the following greatly appreciated. I have some C++ code I've inherited which decrypts certain structures/byte arrays; I've been trying to write a test program in VB.net which exactly mimics the C++ decryption routine using the same functions, ie. Using the WinAPI Crypto calls; in testing, CryptAcquireContext, CryptCreateHash, CryptHashData and CryptDeriveKey all succeed; However, both the CryptEncrypt and CryptDecrypt functions fail with the Invalid Parameter error, even in the most simple scenario; (I am aware of the System.Security.Cryptography namespace.and I will resort to this.but the C++ code includes structures with unions, and for testing, it seemed better to try the WinAPI route first) the sample code is below.I am on Win7x64 sp1, vs 2010 sp1.

Geoff Chappell, Software Analyst ADVAPI32 Functions The large table on this page lists all the functions that appear in the export directory of any known version of ADVAPI32.DLL. For each function, the table gives just a brief summary of the applicable ADVAPI32 versions and of the function’s status with respect to Microsoft’s documentation.

This master list is the key to other lists. More detail on each function’s availability and documentation status may be found by looking for each function in other lists according to the function’s first version. In the Table of Contents, expand the entry for to get pages for each version. Additional explanatory notes follow the table.
