示例1: GetPassphraseFromUser
// The highest-level possible interface (used by the API)
//
// NOTE: this version circumvents the master key.
OTPassword* LegacySymmetric::GetPassphraseFromUser(
const String& pstrDisplay,
bool bAskTwice) // returns a
// text
// OTPassword,
// or nullptr.
{
OTPassword* pPassUserInput =
OTPassword::CreateTextBuffer(); // already asserts.
// pPassUserInput->zeroMemory(); // This was causing the password to come
// out blank.
//
// Below this point, pPassUserInput must be returned, or deleted. (Or it
// will leak.)
const char* szDisplay = "LegacySymmetric::GetPassphraseFromUser";
OTPasswordData thePWData(
(!pstrDisplay.Exists()) ? szDisplay : pstrDisplay.Get());
// -------------------------------------------------------------------
//
// OLD SYSTEM! (NO MASTER KEY INVOLVEMENT.)
//
thePWData.setUsingOldSystem(); // So the cached key doesn't interfere,
// since
// this is for a plain symmetric key.
// -------------------------------------------------------------------
