Also kostenlos, wobei deren Lizenz eine eigene sein soll, die "nicht 100%tig dem eigentlichen Open Source entspricht".Q: Will TrueCrypt be open-source and free forever?
A: Yes, it will. We will never create a commercial version of TrueCrypt, as we believe in open-source and free security software.
Also laut FAQ geht das mit der neuen Version... hab mich mal damit beschäftigt, leider muss man bevor man alles verschlüsstel, alles formatieren, sonst hätt ichs schon längst gemacht...
http://www.truecrypt.org/docs/?s=system-encryptionNote that TrueCrypt can encrypt an existing unencrypted system partition/drive in-place while the operating system is running (while the system is being encrypted, you can use your computer as usual without any restrictions). Likewise, a TrueCrypt-encrypted system partition/drive can be decrypted in-place while the operating system is running. You can interrupt the process of encryption or decryption anytime, leave the partition/drive partially unencrypted, restart or shut down the computer, and then resume the process, which will continue from the point it was stopped.
