I am trying to open a efs encrypted file using OpenEncryptedFileRaw. According to the documentation, the process should have SeBackupPrivilege for opening a encrypted file. From process explorer I can confirm that the process has the necessary privileges for this operation, but still I see access denied error when trying to open the Encrypted file.I am also running both command line and visual studio as administrator.
Code Snippet:
PVOID context;
DWORD ret = OpenEncryptedFileRaw(fileName,0,&context);
One more thing I noticed was, even though I specify the fileName to be a name that doesn't exist I still get access denied error. Do let me know if I am missing any basic setting or configurations.
