John wants to know if there's a cross platform alternative to TrueCrypt since development of it ended. Leo says that BitLocker is Microsoft's file vault, and Apple's is called FileVault. Both work great, but they aren't cross platform. Leo says that TrueCrypt is still around, but that the writer of it allegedly took to the Internet and said it wasn't safe anymore. It's been audited and so far seems to still be legit. So who knows? Leo doesn't know of any open source options anymore. BitLocker is a good alternative.
Walter got a new computer and just updated it to Windows 8.1. But he's thinking of downgrading to Windows 7 because he likes TrueCrypt's whole disk encryption. Leo says that BitLocker is good and it's built into Windows 8.1. Fast and effective. He can get BitLocker through Windows 8.1 professional, but Windows 8.1 automatically encrypts by default, and he'll have to use his Microsoft account to login.
Pete would like to encrypt his hard drive so nobody could use his computer unless they had the password. Leo says the easiest way to do this is to use the file lockers that the OS comes with. Windows has BitLocker, and Apple has FileVault. He can turn them on in the OS. But some people don't trust them because they don't know if there's a back door built into them for the NSA. So open source options like TrueCrypt exist. Can he just encrypt folders? Leo says absolutely. He can also encrypt external drives.
Dave is looking for a good backup solution for both business and personal. He wants to encrypt the data and back it up. Leo says that if Dave turns on encryption on the drive, that's effective. The OS has encryption: File Vault for the Mac and BitLocker for Windows. He'll have to be sure he backs up the certificate and doesn't lose it. Third party options that work include TrueCrypt.
