From c27461572ca09705c16f26a1e9128ff3a4ebdda0 Mon Sep 17 00:00:00 2001 From: Mounir IDRASSI Date: Tue, 16 Dec 2014 00:14:42 +0100 Subject: Windows: Enhance performance by implementing the possibility to choose the correct hash algorithm of volumes during various operations (mount, change password...). In case of system encryption, slightly speedup Windows startup time by making the driver pickup the correct hash algorithm used for the encryption. --- src/Driver/Ntdriver.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'src/Driver/Ntdriver.c') diff --git a/src/Driver/Ntdriver.c b/src/Driver/Ntdriver.c index e7a55b02..4476adb2 100644 --- a/src/Driver/Ntdriver.c +++ b/src/Driver/Ntdriver.c @@ -1364,7 +1364,9 @@ NTSTATUS ProcessMainDeviceControlIrp (PDEVICE_OBJECT DeviceObject, PEXTENSION Ex { MOUNT_STRUCT *mount = (MOUNT_STRUCT *) Irp->AssociatedIrp.SystemBuffer; - if (mount->VolumePassword.Length > MAX_PASSWORD || mount->ProtectedHidVolPassword.Length > MAX_PASSWORD) + if (mount->VolumePassword.Length > MAX_PASSWORD || mount->ProtectedHidVolPassword.Length > MAX_PASSWORD + || mount->pkcs5_prf < 0 || mount->pkcs5_prf > LAST_PRF_ID + || mount->ProtectedHidVolPkcs5Prf < 0 || mount->ProtectedHidVolPkcs5Prf > LAST_PRF_ID ) { Irp->IoStatus.Status = STATUS_INVALID_PARAMETER; Irp->IoStatus.Information = 0; @@ -1378,6 +1380,8 @@ NTSTATUS ProcessMainDeviceControlIrp (PDEVICE_OBJECT DeviceObject, PEXTENSION Ex burn (&mount->VolumePassword, sizeof (mount->VolumePassword)); burn (&mount->ProtectedHidVolPassword, sizeof (mount->ProtectedHidVolPassword)); + burn (&mount->pkcs5_prf, sizeof (mount->pkcs5_prf)); + burn (&mount->ProtectedHidVolPkcs5Prf, sizeof (mount->ProtectedHidVolPkcs5Prf)); } break; -- cgit v1.2.3
