TrueCrypt adds Full Hard Disk Encryption, Mac OS X Support

Filed under Cryptography


Big news from the TrueCrypt Foundation yesterday…the new version of TrueCrypt (v5.0) supports full disk encryption and/or encryption of the system partition using pre-boot authentication. In addition, Mac OS X support was added and a GUI interface for the Linux version is now included. From the TrueCrypt web site:

“TrueCrypt can on-the-fly encrypt a system partition or entire system drive, i.e. a partition or drive where Windows is installed and from which it boots (a TrueCrypt-encrypted system drive may also contain non-system partitions, which are encrypted as well).”

Full disk encryption only works for drives with Windows installed in this new version (including Vista). This is great news considering TrueCrypt is a free, open source encryption solution. Now there is no excuse for companies to deploy full disk encryption to laptops containing customer, employee, or other confidential data. I personally use TrueCrypt with my USB thumb drive and is simply the best mobile encryption solution I have ever used (and it’s free).

Stay tuned for my review of TrueCrypt’s full disk encryption in an upcoming article.

Cross Platform File Encryption – Drop Secure Professional 2.0

Filed under Cryptography

Pretty unique file encryption program available for Mac and Windows now available. It’s called Drop Secure Professional 2.0. What makes this program different then others is that it:

“…starts by dividing up the file into small chunks. By default, those chunks are 256 bytes long. Each chunk is encrypted with a separate cipher, using a separate password that is derived from a hash of information provided by the user, from the archive, and from the data being encrypted. This password is used only once for that one chunk of data, and then discarded. The chunks of data are placed in an archive file, with pertinent information encrypted again as a group.”


“When used with one of the encryption types that support 256 bit key sizes, Drop Secure ProTM meets and exceeds recommendations for security and key strength set by DCSSI, BSI, and the NSA.”

Not a bad investment for $57. You can download a 30-day trail here.

TrueCrypt – Free Open-Source On-The-Fly Disk Encryption Software

Filed under Cryptography

A few months ago I heard on the “Security Now!” podcast that there was a really good open-source encryption application that is so good that it is literally scary. It is so good, and so well done that you can use it for “plausible deniability“. In TrueCrypt, this provides you with (from the TrueCrypt website):

1. True hidden volumes.

2. It is impossible to identify a TrueCrypt volume. Until decrypted, a TrueCrypt volume appears to consist of nothing more than random data (it does not contain any kind of “signature”). Therefore, it is impossible to prove that a file, a partition or a device is a TrueCrypt volume or that it has been encrypted.

Pretty cool eh? As a bonus, you can create a TrueCrypt volume on a USB flash drive for portablity. So now you can carry a USB flash drive around with nothing but “random data”…and if you are caught with the secret plans to take over the world..they can be safely hidden within a secret volume..which on the outside contains your income tax returns that you were safeguarding. 🙂 I hope to do a full review of TrueCrypt in the near future and let you know how the installation and ease of use is.
