I'm trying to get all major functionality of an application, eMule, to work under Wine. eMule uses the following crypto-related imports: ADVAPI32.AdjustTokenPrivileges ADVAPI32.CryptAcquireContextA ADVAPI32.CryptGenRandom ADVAPI32.CryptReleaseContext ADVAPI32.LookupPrivilegeValueA ADVAPI32.OpenProcessToken ADVAPI32.RegCloseKey ADVAPI32.RegCreateKeyExA ADVAPI32.RegDeleteKeyA ADVAPI32.RegDeleteValueA ADVAPI32.RegEnumKeyA ADVAPI32.RegEnumKeyExA ADVAPI32.RegOpenKeyA ADVAPI32.RegOpenKeyExA ADVAPI32.RegQueryValueA ADVAPI32.RegQueryValueExA ADVAPI32.RegSetValueExA Some of these, ie, CryptAcquireContextA(), when called in turn make calls to CryptoAPI. It seems CryptoAPI isn't implemented fully in Wine yet because eMule is unable to (indirectly) utilize CryptoAPI's simple RSA services. I've tried using the native Win98 and XP advapi32.dll without success, and also tried using the WinXP native rsaenh.dll along with the following fake registry modifications: ===========[HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography] "MachineGuid"="5436453a-bc53-d43a-22a8-88433ae03991" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Defaults\Provide \Microsoft Base Cryptographic Provider v1.0] "Image Path"="rsaenh.dll" "SigInFile"=dword:00000000 "Type"=dword:00000001 [HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Defaults\Provide \Microsoft Strong Cryptographic Provider] "Image Path"="rsaenh.dll" "SigInFile"=dword:00000000 "Type"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Defaults\Provider Type \Type 001] "Name"="Microsoft Strong Cryptographic Provider" "TypeName"="RSA Full (Signature and Key Exchange)" =========== (The GUID came from a patch I found which was submitted to WineX CVS.) rsabase.dll likewise doesn't work. I'm unsure as to what more should be done to make valid CSPs available through CryptoAPI/advapi32 to my Wine applications. All I need to get working for eMule is RSA, but DSS would be nice to have also (though I haven't tested DSS yet). What is the current status of CryptoAPI and advapi32 emulation? I read that someone is working on tying CryptoAPI to libgcrypt. What is the status of that? Cheers.
