I'll quote it here anyway, for the benefit of other readers -
What’s A Backdoor?
• A method to bypass data encryption or security
• Does not require the password or passphrase to be known
• Saves time, cost and effort to access encrypted or secured data
• Allows data to be accessed, copied and even modified without tipping off the owner
• Currently available for major encryption software – Microsoft Bitlocker, FileVault, BestCrypt, TrueCrypt, etc
• Currently implemented by major cloud storage provider to comply with NCMEC requirements
Can I get a direct quote? I'm not seeing any mention of TC on p15 or any other page.
