Azure RMS test app

Application illustrates use of unmanaged RMS API with RMS Connector. According to the input it will encrypt or decrypt file.

Requirements

• Installed and configured Azure RMS Connector on a server
• Installed AD RMS Client 2.1
• Applied registry settings that will redirect all RMS communication to RMS Connector. This registry setttings should by applied on computer/server that is used for running the AzureRMSTestApp

Description

The application implements three methods:

• List all available RMS templates (IpcGetTemplateList)
• Decrypt encrypted file (IpcfDecryptFile)
• Encrypt file (IpcfEncryptFile)

Unfortunatelly method that is used for file encryption does not work and ends with an error IPCERROR_NEEDS_ONLINE even if offline flag is set to false.

SafeFileApiNativeMethods.IpcfEncryptFile(
    inputFile: filePath,
    templateId: template.TemplateId,
    flags: SafeFileApiNativeMethods.EncryptFlags.IPCF_EF_FLAG_DEFAULT,
    suppressUI: true,
    offline: false,
    hasUserConsent: true,
    parentForm: null,
    symmKey: null,
    outputDirectory: null);

According to the IPC log the error arise earlier in ippuseridentity.cpp:Microsoft::InformationProtection::IPPUserIdentity::GetNewIdentity which ignores offline flag set to false.
