LSARetrievePrivateData (advapi32)
 
.
NOTE
Can a WIKI page be renamed? I typed "LSA" instead of "Lsa"
Summary
The LsaRetrievePrivateData function retrieves private data that was stored by the LsaStorePrivateData function.

C# Signature:

[DllImport("advapi32.dll")]
private static extern UInt32 LsaRetrievePrivateData(
     IntPtr policyHandle,
     [MarshalAs(UnmanagedType.CustomMarshaler,MarshalTypeRef=typeof(LSAStringMarshaler))] string KeyName,
     [MarshalAs(UnmanagedType.CustomMarshaler,MarshalTypeRef=typeof(LSAStringMarshaler))] ref string PrivateData
);

VB Signature:

Private Declare Function LsaRetrievePrivateData Lib "ADVAPI32.dll" (ByVal PolicyHandle As Long, ByRef KeyName As LSA_UNICODE_STRING, ByVal PrivateData As Long) As Long

User-Defined Types:

Private Type LSA_UNICODE_STRING
   Length          As Integer  ' WORD
   MaximumLength   As Integer  ' WORD
   Buffer          As Long     ' PWCHAR - pointer
End Type

Alternative Managed API:

Do you know one? Please contribute it!

Notes:

See LsaOpenPolicy for the custom marshaler and some more info on it.

Tips & Tricks:

Do not use the LSA private data functions. Instead, use the CryptProtectData and CryptUnprotectData functions.

(However, these won't do when you need to modify COM runas Passwords ...)

Sample Code:
