I have to submit my Video presentation and other pptx files so i need them to be encrypted. .

Is there any Software or Application available in Ubuntu 12.04 Repositories for doing this.

I tried this Link which uses GPG file encryption method , but however , the platform to be presented on might be Windows , so i am not sure whether to use this or not, also after using will this work or not.

I want to mention i am not talking about DVD encryption , but rather Format-wise encryption.

For example - .avi, .mp4,.flv.

I am using Ubuntu 12.04 64-bit system.

NOTE:

I just realized i can use secure archiving like zip or rar, but that would defy the need for such Encryption application.

Also i can rename them to any unsuspecting file , and removing the extension .For Example : .recycle.[For the time being i will use one of these methods , but will keep an eye for such app if available, so i am not closing this question until then]

After searching i found there are Windows software available for that purpose, but in Linux i was unsuccessful.

What do you mean by encryption exactly, or why you need them to be encrypted? You mean DRM? –  dobey Jun 25 '12 at 16:48
    
Encryption in a way that they need to ask password for accessing them. –  atenz Jun 25 '12 at 16:51
    
Yes ,open for any open-source suggestion . –  atenz Jun 25 '12 at 17:01
    
I meant , if i packed them in password protected Zip or rar archive that will be a alternate solution , but crackable though using Zip password recovery like software .If i stick to it for such encryption needs , then i will isolate the need of Video encryption like utilities. I apologise if my English is not that clear , you are free to edit it .Also for now i am using this archiving method , so i am keeping this Q open if, if not suitable please post so , so i can delete it. –  atenz Jun 25 '12 at 17:06
