Encryption

windows

To encrypt your entire system you have a choice between two methods:

• use Bitlocker from microsoft which is integrated in windows pro/enterprise (not in home edition, though we have a campus upgrade license to enterprise)
• use VeraCrypt open source software

It is adviced to use Bitlocker, unless you have a problem with the possibility that Microsoft has made a backdoor in bitlocker you should use VeraCrypt instead.

= comparison Bitlocker and Veracrypt

Advantages Bitlocker over Veracrypt

   - automatic unlocking at startup  with TPM (no password need) => user only needs to login as it is a none-encrypted laptop
   - windows recovery/repair supports bitlocker  => for veraCrypt you must make special repair disk which is unique for the laptop!

Advantages Veracrypt over Bitlocker

    - open source -> more likely that there is no backdoor
    - more possibilities eg. stronger encryption! only drive encryption, image encryption etc.
    - supported on linux and os x  ( system encryption only for windows!!)
