Does CryptProtectData() of wine work well for .rdp file?

[fanfoxle]

I am attempting encrypt the RDP password on Linux.
For example, "Letmein" in a .rdp file is:
password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

In windows environment, we can call CryptProtectData() in crypt32.dll.
In Linux, however, there is no crypt32.dll, so it's a problem for me to encrypt the password which is also can be recognized by a remote windows OS.
I checked the source code of Protectdata.c of wine. It says that :
/*
* The Win32 CryptProtectData and CryptUnprotectData functions are meant
* to provide a mechanism for encrypting data on a machine where other users
* of the system can't be trusted. It is used in many examples as a way
* to store username and password information to the registry, but store
* it not in the clear.
*
* The encryption is symmetric, but the method is unknown. However, since
* it is keyed to the machine and the user, it is unlikely that the values
* would be portable. Since programs must first call CryptProtectData to
* get a cipher text, the underlying system doesn't have to exactly
* match the real Windows version. However, attempts have been made to
* at least try to look like the Windows version, including guesses at the
* purpose of various portions of the "opaque data blob" that is used.
*
*/

So I really wanna know that whether this algorithm provided by wine works well.

Thanks!
Best Regards!

Hi,

probably noone on this list will be able to answer your question. You can either file a bug or ask on wine-devel, there should be a wine dev (Juan Lang) who at least could tell you, if wine is going to implement this kind of functionality.
