First Use of RIPA to Demand Encryption Keys
kylehase writes "The Regulation of Investigatory Powers Act (RIPA) is being used for the first time to force an animal activist to reveal encryption keys for encrypted files she claims to have no knowledge of. According to the article, she could face up to two years if she doesn't comply."
any forensic team with an ounce of competence will copy the original HDD and work off the copy, so that just won't work.
Having a known self destruct switch may cause a person to end up even worse trouble. This is a discussion that occurs periodically on a number of cryptography forums.
Almost all police departments will image the drive, then present the person with the image to decrypt. If the image gets stung by a self destruct Trojan, then the police will know that its not a forgotten password, and then proceed to use rubber hose decryption to obtain the contents of the drive.
Filesize arithmetic?
You never used Truecrypt eh? It's not a zip file. It acts as a virtual hard drive partition that can be mounted as a drive.
When you create the volume it generates random bits throughout the virtual partition. You can copy whatever files you want onto the virtual partition, the rest of it is random noise. You may or may not choose to have additional hidden encrypted partitions within that noise. Adding up the size of know files tells you nothing about what may or may not lurk in the rest of the space on the virtual partition.
TrueCrypt allows hidden volumes, indistinguishable from one volume. The file size is constant.
TrueCrypt works very, very well. I use it with just one volume to protect passwords and other files.
When you don't want to encrypt a volume, but just a file, Gnu Privacy Guard is best.
Several animal rights groups in the UK are officially designated terrorist organisations, because frankly they engage in acts of terror.
