How to decrypt files in cms format?

Hi,

I had some of my files hidden in cm vault which i had transferred onto my pc once.

I tried to retrieve those important photos back from my pc but it couldn't happen, coz the files were in cms. format. I don't know how to decrypt them. Please tell me how to do so.

It is also not possible for me to get those photos back from CM vault either as my phone (which had the photos on vault) was damaged in an accident. I tried to retrieve them from logging onto to my old ID on CM vault on my new phone, but it said that there weren't any photos or data present.

Those photos are very important for me which i really can't afford to lose. A help would really really be appreciated.

Thank you. :)
