4 <title>Encrypting a VM</title>

8 Encrypting a VM can be done either using VirtualBox Manager or the
9 <userinput>VBoxManage</userinput>. To encrypt an unencrypted VM with
10 <userinput>VBoxManage</userinput>, use:
11 </p>
12 <pre xml:space="preserve">VBoxManage encryptvm <varname>uuid</varname>|<varname>vmname</varname> setencryption --new-password <varname>filename</varname>|- \
13--cipher <varname>cipher-ID</varname> --new-password-id <varname>ID</varname>
14 </pre>
15 <p>
16 To supply the encryption password, point
17 <userinput>VBoxManage</userinput> to the file where the password is
18 stored or specify <codeph>-</codeph> to let
19 <userinput>VBoxManage</userinput> prompt for the password on the
20 command line.
21 </p>
22 <p>
23 The cipher parameter specifies the cipher to use for encryption
24 and can be either <codeph>AES-128</codeph> or
25 <codeph>AES-256</codeph>. The appropriate mode of operation,
26 such as GCM, CTR, or XTS will be selected by the VM depending on
27 the encrypting component. The specified password identifier can
28 be freely chosen by the user and is used for correct
29 identification when supplying multiple passwords for the VM.
