I want to perform encryption – decryption of certain audio – video files.
Can anyone suggest me some suitable algorithms in cocoa, objective- c, c, or c++ to accomplish it?
You can suggest me some link and/ or third party software for it.
Thanks,
Miraaj
Any stream cipher should work for you. I would suggest AES. Numerous FOSS implementations are available.
