New Post: I'd like to get log of some values in running time.

I downloaded source code at this site and compiled on Ubuntu 16.04(VM)

It is working without any problem.

I am trying to get noise sources of Veracrypt's random number generator.
(I'm student studying RNG)

So, i modified this source in order to monitor running time noise sources.

First, i inserted "printf" function wherever noise sources are mixed into the pool.

But it is not working. (the veracrypt program works well)
(after modifying, i luanched #/src/Main/veracrypt or veracrypt_install_gui_x64.sh on terminal)

Second, wherever mixing point in the source code, i inserted fprintf function.

At Randinit function in #/src/Common/Random.c, I opened file pointer.
(the FILE pointer is allocate as global variable)

But it is not working...

Because i will estimate a entropy of noise sources, i need to get values.

how can i do??

Thanks in advance.

New Post: Win10 encrypted Systempartition -> "Automatic Repair" on Boot

Hi!

I bought an Acer Cloudbook One with Win10 on SSD preinstalled. First, i deactivated "Secure Boot" in BIOS and then installed Veracrypt 1.1.8a (latest). The Systempartition was encrypted with a prior successful test. Upon reboot Windows10 is stuck in the "Automatic Repair" routine. Do you have any idea how i can fix this? In automatic repair -> advanced options / troubleshooting / advanced options / -> command prompt -> entering "bcdedit / set recovery abled no" is useless. On reboot it enters the "Automatic Repair" again.

Thanks!

If /dev/sda1 partition has the boot flag set then how are you booting into /dev/sda5 to run GRUB? Is the disk using GPT or MBR?

Rated 5 Stars (out of 5) - This software has become my only encryption solution and meets all my needs. It completely replaces the TrueCrypt and incorporates great new features and now, new algorithms, PIM, bug fixes, more security etc. I'm so happy with the VeraCrypt that even made a small donation and i will make others whenever I can. Thank you very much Mounir! You are our hero.

New Post: batch file hangs when running veracrypt

I think I have figured out what your setup is. Veracrypt is set to run when you log on, and you have set up your external drives as 'Favorite Volumes', selecting the 'Mount selected volume when its host device gets connected'. When configuring Favorite Volumes, you can specify the drive letter they mount to, and the PIM. On connection, you should be asked for the password, and the drive automatically mounts.
In which case, the veracrypt /a line in your batch file is redundant; it doesn't mount the drives, they're already mounted, and the line does nothing but launch the GUI, which you have to close before anything else happens. Remove that line, and your file should run.
There are other issues with your batch file eg you don't check for non-existence of y: (for when the alternative drive gets used), but you can easily sort that out.

veracrypt is not set to run at log on. it is run manually and your correct the 2 external drives are assigned as favorites with their drive letter. the batch file is working fine now just had to place a timeout statement to allow vc enough time to mount the drives. as far as the non-existence of y no worries its done in the true batch i only posted that part as an example. thanks for all the help and suggestions.

Created Unassigned: Re-Activating main window after mounting [543]

There are multiple favorite volumes defined with the same PW. After "Mount Favorite Volumes" the Veracrypt main windows gets activated, pops into the foreground, and the "Dismount" button is the active UI element.
As long as the mounting process takes some time users/I switch to other apps and perform some actions there. When Veracrypt pops into the forground it often happens that typing can't be stopped fast enough and a "Return" is hit. This will cause the last mounted volume to dismount again because "Dismount" is the active element.
There are two options:
1. (my favorite) don't activate the Veracrypt main window after the operation has been performed if the user switched applications.
2. Don't make any of the UI elements the default element.
Thanks and keep up the good work!

Still rather puzzled, then. When you say veracrypt is run manually, do you mean, it's run for the first time after logon using your batch file?

The disk is using MBR. It appears you are correct, GRUB is installed in the MBR, and appears to point to SDA5 for the config file.

This is what I can find about my GRUB install:

"Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of 
the same hard drive for core.img. core.img is at this location and looks 
in partition 97 for ."
and
"
sda5: __________________________________________________________________________
File system:       ext2
Boot sector type:  -
Boot sector info: 
Operating System:  
Boot files:        /grub/grub.cfg
"

This thread seems to relate to your setup and what you're trying to achieve. However, that refers to two disks but you are only using one so you only have one MBR for either GRUB or the VeraCrypt bootloader.

I guess you could install GRUB to /dev/sda5, set the boot flag to that partition and configure GRUB to boot Linux and Windows from their respective partitions. Encrypt Windows so the VeraCrypt bootloader is installed the MBR and then chainload that from GRUB?

New Post: Windows 10 - Can't boot and start encryption - why?

Hi there, I've installed a 64 version of Windows 10. The rescue disk is OK, after it tries to reboot the system, it says: "Selected boot image did not authenticate. Cancel image load and boot to next boot option". The encryption didn't start, and I didn't ask any password.

In this case, I can't reinstall windows 10 system, just if I restore everything to defaults in BIOS. What's the problem? (It seems some settings it locked in BIOS, for example legacy mode, I can't enable it). Hope somebody can help me.

New Post: Corrupted filenames after mounting windows-created TrueCrypt container in Linux

Hi, on Ubuntu I mounted a TrueCrypt container that I had once created in Windows XP (TrueCrypt mode used). Although I saw files structure and their content, non-English characters (special Czech letters) in the filenames were represented by '?' and similar characters.
Is there any option to be turned on to show filenames properly? Did I miss something?

Thanks in advance for your help!

New Post: Extremely quick mount in Linux version?

Maybe I did not understand well the docs, but mounting on linux behaves really strange. Looks like the VeraCrypt on Linux doesn't use the PIM (?) or is using some backdoor.

At first the setup of my test:
  • Very old laptop, i7-m620, 8GB RAM, 2 physical disks.
  • Disk 1: 1 partition, Windows 7 64 bit, system encryption, VeraCrypt bootloader.
  • Disk 2: first 2 partitions (unencrypted): Ubuntu 16.04 64 bit + swap, third one is whole encrypted NTFS also with VeraCrypt.
  • Booting from disk 1 or disk 2 is controlled by BIOS.
  • I am not using PIM, so it means I am using default PIM.
From Linux I am often using those two encrypted partitions - system disk 1 and nonsystem partiton from disk 2.

There are significantly different mounting times from those systems!

System drive encrypted mount
  • VeraCrypt Bootloader (16bit) + pass OK: 33.20 s
  • Ubuntu 16.04 (64bit) + pass OK: 3.66 s (!!!!!)
  • VeraCrypt Bootloader (16bit) + pass BAD: 32,90 s
  • Ubuntu 16.04 (64bit) + pass BAD: 22.02 s
Nonsystem drive encrypted mount
  • Windows 7 (64bit) + pass OK: 10.62 s
  • Ubuntu 16.04 (64bit) + pass OK: 3.37 s (!!!!!!)
  • Windows 7 (64bit) + pass BAD: 33.73 s
  • Ubuntu 16.04 (64bit) + pass BAD: 56.28 s (!!!!!)
Times are average from several tests.

I am OK with boot mounting to Windows (system drive encryption) about 30 seconds. But what the heck with linux - it can mount the same drive in about 3 seconds??? And on the other side - bad password for nonsystem drive means about 30 seconds of waiting on Windows while on linux it is almost one minute.

Looks like the linux version of VeraCrypt is working differently with PIM (maybe). I cannot say, if I am sad that the Windows version cannot use this method or I am sad that this method exists...

This is a joke of multi threading and order of hash to check.

The following facts:
  1. Windows uses several threads to mount.
  2. Linux uses one thread.
  3. Hash check order and speed: SHA-512(~200MB/s), Whirlpool(~85MB/s), SHA-256(150MB/s), RIPEMD-160(150Mb/s), Streebog (70MB/s)

Rated 5 Stars (out of 5) - Fix TrueCrypt vulnerability allowing detection of hidden volumes presence (reported by Ivanov Aleksey Mikhailovich, alekc96 (at) mail dot ru) Is this vulnerability really only possible on windows, or have you not been able to fix it on the other platforms yet?
