+ <para>
+ The <command>VBoxManage encryptvm</command> command enables you to
+ change the encryption or add and remove user passwords for the
+ virtual machine (VM). The following sections describe the subcommands
+ that you can use:

+ <para>
+ The <command>VBoxManage encryptvm
+ <replaceable>vmname</replaceable> setencryption</command> command
+ changes encryption of a VM.
+ </para>
+ <para>
+ Use the <option>--old-password</option> to supply old encryption
+ password. Either specify the absolute pathname of a password file
+ on the host operating system, or <literal>-</literal> to prompt
+ you for the old password.
+ </para>
+ <para>
+ Use the <option>--cipher</option> option to specify the
+ new cipher for encryption of the VM. Only <literal>AES-128</literal>
+ and <literal>AES-256</literal> are supported. Appropriate mode
+ GCM, CTR or XTS will be selected by VM depending on encrypting
+ component.
+ </para>
+ <para>
+ Use the <option>--new-password</option> option to specify the
+ new password for encryption of the VM. Either specify the absolute
+ pathname of a password file on the host operating system, or
+ <literal>-</literal> to prompt you for the new password.
+ </para>
+ <para>
+ Use the <option>--new-password-id</option> option to specify the
+ new id for the password for encryption of the VM.
+ </para>
+ <para>
+ Use the <option>--force</option> option to make the system
+ to reencrypt the VM instead of simple changing the password.

+ checks the correctness of the supplied password.
+ </para>
+ <para>
+ The password can be supplied from file. Specify the absolute
+ pathname of a password file on the host operating system. Also,
+ you can specify <literal>-</literal> to prompt you for the password.
