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.
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.
