I have application which exports data in csv file which is stored in Document’s Directory.
Also I have enabled File Sharing in my app with iTunes so that whenever i will connect my iPhone with iTunes it will allow me to save csv file. But my data needs security, so i want generate Password for my CSV file, So that whenever we open file in computer, it will ask for Password. How to achieve generating Password protected file in iPhone??
Well, you would have to create a disk image (.dmg file) in order to have the file password protected once it was on your computer. I don’t think this is possible in iOS. I think your only solution would be to use an encryption/decryption algorithm. Store encrypted data into the file, and use your algorithm to decrypt the file once it is on your desktop. Here is a solution for encrypting/decrypting NSData.
