  2. Introduction • TrueCrypt software is based on E4M software • Invented by Paul Re Roux in 1997 • Abandon in 2000 • “TrueCrypt Team” created TrueCrypt in 2004 • First release version 1.0 includes Win 98/ME support • Paul Re Roux claimed TrueCrypt violated E4M GPL • Arbitration in second release (1.oa) • Remove Win98/ME, become “TrueCrypt Foundation”, and acknowledge E4M in the TrueCrypt’s GPL and WebPage

  3. Introduction contd. • TrueCrypt latest version is 5.1 • Offered various encryption algorithm for volume/partition • Able to encrypts file or folder only to the entire system • Standard encryption is AES with 256 bit key • Most advance encryption is 512 bit hash encryption like in LINUX’s MD5 • Famous since E4M to TrueCrypt because of its OTFE (On The Fly Encryption) method

  4. TrueCrypt Layout • The Symbol or Icon • The Layout of the software

  5. Features • “Create a file container” • Standard volume in already existed storage system • “Create a volume within a non standard partition or device” • Creates secure file container in USB drive • “Encrypt the entire partition or entire system drive.” • Encrypt the entire partition of a Hard Drive

  6. Features contd. • Various selection of encryption algorithms • The ciphers (cryptography): • AES (256 bit) • Serpent (modified AES) • Two-Fish (modified AES) • The hash ciphers: • RIPEM-160 (160 bits) • SHA-2 (512 bits) • Whirlpool (512 bits)

  7. Features contd. • After selection of cipher, then we can format the volume or partition • Then setup the password • All in GUI (Graphical User Interface)

  8. More Advance Feature • A trick to use the software w/o installing the entire package in the computer • Able to open the encrypted file in any computer • Any cipher or encryption algorithm can be used • OTFE (On The Fly Encryption) approach for flash drive: • Example to create standard volume • Drive is set to K: • Filename is tcFolder

  9. More Advance Feature contd. • OTFE in 5 steps: • Step 1: Extract the latest version or any version of TrueCrypt and copy TrueCrypt.exe, TrueCrypt Format.exe and TrueCrypt.sys to the USB drive. • Step2: Run TrueCrypt.exe, select file container as the first option, choose any encryption, and format the file container. For example: the file we want to encrypt is named “tcFolder”. • Step3: Create the mount.bat with two lines of codes such as: • Line 1: TrueCrypt /v tcFolder /l K /m rm /auto /qexplorer • Line 2: K: • Step 4: Create the unmount.bat with one line of code such as: • Line 1: TrueCrypt /d K /q • Step 5: Create autorun.inf with one line of code. (Create autorun.txt first and rename to .inf later) • Line 1: [autorun]open=mount.baticon=

  10. OTFE Demonstration • Explain how to use a TrueCrypt in OTFE method • Difference between using the shortcut & GUI
