 * I have used wp-online backup on 2 previous sites both with ecryption, however
   on my 3rd site I am getting this message:
    “Your server does not support encryption
   Encryption requires the php-mcrypt extension with AES or DES cipher support and
   a compatible message digest framework (php 5.1.2 where it is builtin, php-hash
   or php-mhash). Encryption is highly recommended and you should consider contacting
   your host regarding these requirements” And under Decrypt Backup: “Encryption
   requires the php-mcrypt extension with AES or DES cipher support and a compatible
   message digest framework (php 5.1.2 where it is builtin, php-hash or php-mhash).
   Your server does meet these requirements, therefore you cannot this plugin installation
   to decrypt any encrypted backups.” I am using the same host (123-reg.co.uk) &
   the same version of wordpress on all sites. Do you know why this 3rd site won’t
   allow encryption?

 * Hi purplebabyhippo,
 * Can you provide the information from the Help & Support section?
 * I wonder if your other sites are running on PHP 5 and this 3rd one is configured
   to be PHP 4 or something for one reason or another. The mcrypt plugin is widely
   available on most web hosts, and we only require the mhash if you’re on PHP 4,
   and it is usually the mhash that ends up missing in these instances (it’s a not
   as widely available). On PHP 5 it’s all builtin to PHP so we only need the mcrypt,
   which as said is widely available

 * Hello!
 * I urgently need some help because my site is also telling me that encryption 
   is unavailable. I am wondering how I can access this, to be able to do a backup?(
   We are changing servers, and there is no one for me to contact regarding any 
   access codes. Would there be a plugin that can get me access for encryption to
   run, and thus for a safe backup to be possible?)
 * Lastly, what are the repercussions of choosing not to encrypt, but still backing
   up the site? Would this be my last resort?
 * Please help!!!

 * Hi kpkmiss,
 * Not encrypting just puts you at risk of the backup getting intercepted. However,
   this is highly unlikely to happen. It also means if you do online backup it will
   sit on our servers unencrypted – whether that’s acceptable to you or not is up
   to you (we have physical security as well alongside the usual network security
   any company would have.)
 * You won’t be able to use encryption without the php-mcrypt module and only your
   host will be able to set this up.
 * Jason.
