Judge rules Truecrypt child porn suspect doesn’t have to give up password

A Florida judge ruled that a suspect involved in a child porn case who had encrypted a laptop and five external hard drives with Truecrypt does not have to give up his password because he is protected by the US Constitution Fith Amendment right not to be a witness against himself.

The man can not be named as he has not be charged with any crime and has now been released from prison where he was being held in contempt of court. John Doe first came to the attention of the police on suspicion of uploading videos of under-age girls to Youtube, the computer IP was traced back to the hotel room where John Doe was staying. According to the ruling it is not enough for the Government to prove that the encrypted drives can store vast amounts of data , the Government would need to show what files are stored inside and the computer forensics expert has admitted that the drives might as well be empty.


This new ruling will help clarify future cases in which someone is compelled to give up his password to law enforcement when requested, at first glance it appears contradictory with an earlier bank fraud ruling where a judge ordered Ramona Fricosu to surrender her password, but they are totally different cases as Ramona Fricosu had been recorded over the phone admitting to hold incriminating evidence inside her encrypted laptop whereas John Doe had never admitted to holding the files the police is after.

Lacie Private-Public AES256 encryption based on Truecrypt

Lacie Private-Public is a multilingual free encryption program for Windows and Mac computers based on Truecrypt, it comes with Truecrypt license included. What makes it different from Truecrypt is its simplicity of use, while Truecrypt will give you many encryption algorithms and options this tool sticks to the standard AES256 encryption and does not give the user any kind of option, you can create an encrypted virtual drive with just three clicks without reading the manual, which is available online. Encrypted containers are saved with the .lc extension and automatically named “La-Private” inside a folder bearing the same name, the software does not need installation you can carry it with you on a USB thumbdrive, however, administrator rights are still needed.

Encrypted containers larger than 4GB can not be created in FAT32 drives, to achieve this you will have to reformat to NTFS (Windows) or HFS+ (Mac). Anyone familiar with virtual drive encryption software will instantly know how to use this program, after creating an encrypted container you will see a new drive letter appear next to your C: hard drive, anything you store in there will be automatically encrypted.

To lock the container right click on Lacie’s logo in Windows toolbar and select dismount, to access the data again execute the program and enter the password. The only possible settings are password change, mount encrypted volume as read-only and timed self-dismounting, Lacie Private-Public appears to be directed towards the 100% newbie person that knows nothing about encryption products and is not interested in learning about them or customization options.

The company claims that there is no backdoor, if you forget your password that is it. Full disk encryption has been eliminated, to use this capability you will have to look for something else, the only advantage Lacie Private-Public seems to have over Truecrypt is that it is extremely simple to use and it should not frighten off computer ignorant people.

Note: This software can not run if you have Truecrypt installed, they both use the same drivers.

GPG Tools Windows Privacy Tray review

WinPT is an open source graphical front end for GnuPG, a compatible OpenPGP software that allows people to exchange encrypted messages and files with other PGP users, without WinPT you would only be able to use GnuPG from the command line which requires a long learning curve, GnuPG is included in the download. After installing Windows Privacy Tray you will be asked to create or import your public encryption keys and associate the program with .asc, .gpg and .sig files. The default extension for encrypted messages is .gpg but this can changed to .pgp in preferences.

All of the needed GPG/PGP functions are available, setting up your preferred keyserver, importing and exporting keys, setting ownertrust, revoking keys, digitally signing messages or files and others. Hotkeys can be used to quickly encrypt and decrypt messages.

public key GPG encryption WinPT

The software includes plugins for Euroda and Outlook Express, key management, and encryption and decryption of text in Windows clipboard. WinPT is a good alternative to GPG4Win, another free OpenPGP compatible tool, I did not notice too many differences in between them, WinPT is lighter and a smaller download, and GPG4Win has a few more features like Claws Mail and a bigger community. You will still need to learn how public key encryption works, this software is not as automated as Enigmail, a GPG Thunderbird plugin, but it can be used to encrypt files and text outside of your email client to store them online for example, so it has more functions. To protect against brute force attacks it is much safer using an encryption key and a password than just a password.

If you are looking for a free alternative to the expensive Symantec PGP Desktop, more suitable for businesses, WinPT will get the job done, an easy and simple way to send encrypted messages or attachments by email with the power of OpenPGP.

DiskCryptor vs Truecrypt comparison

DiskCryptor download is a tiny 750Kb, after installing it you will need to reboot the computer, you might notice that its 64bit drivers come signed by the ReactOS foundation a non for profit organization assisting open source projects not able to acquire an expensive signing certificate to distribute Windows 64bit drivers.

Encrypting my Windows 7 Home Premium 64bit OS, with a fairly powerful Intel i5 2200Hz (quad core) absorbed very low CPU, a steady 7% of the available resources, it took me 20 hours to encrypt a 1TB hard drive, it would have been considerably quicker using just the AES algorithm instead of the cascade algorithm I selected.

DiskCryptor lets you know how long it will take to encrypt your operating system, you can still work with your computer while it is being encrypted, I advice you to temporarily disable power management in Windows and set it to always on, Windows will not notice the hard disk being encrypted and send the OS into hibernation mode believing the computer is inactive, if this happens full disk encryption will stop and only resume once you switch the computer back on, I have found this problem to occur with both DiskCryptor and Truecrypt, more of a Windows problem than to do with the full disk encryption software.

Diskcryptor lets you benchmark the encryption ciphers (Tools>Benchmark) if you have a low spec CPU and are in a hurry you can choose the cipher that performs best in your system,  AES was the quickest for me, by quite a lot of difference in contrast with Twofish and Serpent, once the OS has been encrypted it doesn’t matter what cipher you used to encrypt it, performance will be the same. You can benchmark ciphers in Truecrypt too but since only AES can be used for full disk encryption there is no point in doing it.

DiskCryptor encryption keyfile

DiskCryptor encryption keyfile

Truecrypt will ask you to enter your password after rebooting your computer before encrypting your operating system, DiskCryptor will not, it assumes you entered the passphrase correctly twice as asked and did not make any mistake. When using special signs in your password be aware that in booting up your computer the keyboard has a US layout that will not correspond with a non US keyboard, I searched for a photograph of US keyboard layout on the Internet to make sure there would be no mistakes about what keys to pres.

Unlike Truecrypt, DiskCryptor bootloader is highly configurable, I have my own (Ascii) logo at logon and I instructed DiskCryptor to time out after 30 seconds of inactivity at which point the computer reboots, other options like halt and exit to BIOS are possible. Using DiskCryptor keyfile for full disk encryption is something possible and not supported by Truecrypt, a keyfile will thwart dictionary attacks on your passphrase but this keyfile can not consist of anything it has to be a 64 byte file generated by DiskCryptor.

 Windows 7 FDE specific problem

Unlike Vista, XP and lower Windows versions, when you use a whole disk encryption product on Windows 7, or installing a dual boot, you will notice that Windows 7 automatically creates a 100MB system reserved partition, 24MB contains actual data the rest is there for future use like Bitlocker or system restore, this partition is hidden by Windows and only visible using a live CD or through DiskCryptor or Truecrypt interface.

Windows 7 100MB hidden system partition

Windows 7 100MB hidden system partition

Windows 7 system reserved partition contains some necessary boot files, do not attempt to encrypt Windows 7 system reserved partition like I did because the computer will not boot! There are hacks around to merge that partition with the main Windows 7 operating system, I managed to do it partioning the hard disk with PartedMagic before installing Windows 7 and ignoring Windows installation DVD asking me to create the system reserved partition, everything worked fine until I fully encrypted Windows 7 without the system reserved space and the computer refused to boot.

If you would like to use whole disk encryption in Windows 7 there is no choice but to give in and allow Windows to create the unencrypted 100MB system partition, this shouldn’t be a problem regarding data leakage, you can view the files it contains with a live CD, I managed to see a bootsect.bak file, bootmgr, and System Volume Information folder and a few others with no obvious danger.

 Plausible deniability

DiskCryptor does not support the hidden operating system feature that Truecrypt has but allows you to install the bootloader on an external device, ie. USB thumbdrive or CD-Rom, that is where the files giving away that the operating system has been encrypted and what software has been used for that are stored, if anyone seized your hard drive it would be possible to claim that it has been wiped clean as no identifiable information can be extracted from the HDD other than random data and there is no boot loader.

Plausible deniability appears more sound than Truecrypt hidden operating system, if you give away the password for the non hidden OS in Truecrypt, the timestamps and las activities could give away that the computer has not been used for a long time.

DiskCryptor full disk encryption

DiskCryptor full disk encryption

A computer with no operating system and a wiped hard disk will look very suspicious, claims that it was wiped the day before would be held with incredulity but hard to prove it didn’t happen. Even better, I came across a thread in DiskCryptor forums to have a dual OS system where one of the Windows OS will only boot with the USB thumbdrive plugged in and when not present the other OS will boot, this set up makes one of the partitions look like random data and not like 2 operating systems on one hard disk.

Conclusion Truecrypt vs Diskcryptor

If you have a tablet or netbook without a CD-drive go for DiskCryptor because Truecrypt forces you to burn a recovery CD (there is a work around using CD-drive virtualization software, i.e. Alcohol 120% or using the command line /noisocheck).

If you would like to be able to open encrypted external devices using Linux or MAC go for Truecrypt as DiskCryptor is a Windows only program, if you want to create single encrypted containers go for Truecrypt as DiskCryptor can’t do that.

Something in which Truecrypt beats DiskCryptor is in documentation, Truecrypt manual is very complete and DiskCryptor consists of an incomplete online Wiki, DiskCryptor can make up for this showing off the ‘Blue Screen’ feature, a way to quickly crash your fully encrypted computer allowing you to set the quick emergency shutdown to any hotkey shortcut you like.

Security wise, both Truecrypt and DiskCryptor have the same credentials with their source code open to scrutiny and none of them reviewed by any qualified cryptographer, overall, DiskCryptor has more configuration features than Truecrypt, and Truecrypt is better at cross platform compatibility.

List of programs for full disk encryption

If you encrypt your whole hard drive including your operating system you will not have to worry about wiping data, clearing the Internet browser cache, deleting temporary files and encrypting individual files, all you will have to worry about is choosing a strong passphrase that can not be broken using a brute force attack (trying dictionary words).

The only way to access a fully encrypted operating system is by getting access to the computer while it is switched on (decrytped), you will save lots of time if you decide to encrypt your full operating system, it is not difficult and there is free software for that. Windows Vista and 7 come with BitLocker Drive Encryption for full disk encryption but only the more expensive business high end editions do and it has been designed for businesses with few home user features.

Full disk encryption software without backdoor

Truecrypt (Free): It’s wizard driven menu will guide you through the whole encryption process, there are many algorithm choices, if you do not understand what they mean leave all of the default choices on, they are secure enough for everyone.

Full disk encryption performance

I have been using full disk encryption for over 5 years, I have used DiskCryptor, Truecrypt and DriveCrypt Plus Pack, in all cases there has been no computer slowdown while I was using full disk encryption, even using it on a low performance netbook with an Intel Atom CPU showed no noticeable performance issue.

If you are a home user you do not need to worry about full disk encryption slowing down your computer activities, the software normally needs very low resources to run on.

Free file encryption software BCArchive from Jetico

When you compress files you will be saving computer hard disk space, bandwidth and speeding up data transfers, file compression is useful to get around email maximum file attachments size too. Commendable file compression tools will allow for password protecting of compressed files, the most popular file compression software, WinZip and WinRar both have sound uncrackable file encryption protection, but they are not free, they show you a nagging screen asking you to buy the software.

BCArchive is %100 free from day one and its encryption features beat WinZip and WinRar hands down, this file compression and encryption tool is multilingual, available in Arabic, Chinese, German, Farsi, Russian, Spanish and Turkish, it creates its own .bca compressed encrypted file or a self extracting .exe for people without BCArchive installed to be able to decrypt it.

BCArchive encryption key manager

BCArchive encryption key manager

BCArchive integrates nicely with Windows shell right click, encryption and compression of a file can be done using two mouse clicks, if you use a password that is too short the software will not allow you to encrypt the file forcing you to use a better passphrase, when using symmetric encryption you can choose what encryption algorithm to use, some of the available ones are IDEA, Blowfish 448, AES Rijndael, Serpent, Gost, Cast5 and 3DES, you can choose the hashing algorithm as well SHA1, SHA256, RIPEMD160 or MD5. BCArchive symetric encryption ciphers are all well known in the cryptography community and considered sound, the best is to stick to the defaults if you don’t know which one to use.

It is possible to use asymmetric encryption with public and private secret encryption keys, you can create standard PKCS #12, X.509 public encryption keys within BCArchive key manager or import your own PGP keys created elsewhere, BC Keymanager allows you to import your PGP encryption keys directly from the Internet connecting to a PGP public key server.

To encrypt files use the interface or drag and drop files inside the BCArchive window,  you can compress and encrypted files of up to 2 Terabytes in size. When you view files these are extracted to a temporary folder and securely wiped when the archive is closed, for those who are geeky, BCArchive can be run from the command line.

BCArchive main features

  • Self-extracting of encrypted files
  • Drag and drop of files and Windows shell integration
