I see a lot of people asking for apps that password protect folders and other apps. But how reliable are these password protection apps?
Does the password protection app encrypt the original folder or app and prevent access unless you have the password? If not, someone could simply jailbreak the phone, install iFile and access the entire filesystem, including the password-protected items. This would render the password protection app useless. This means your data isn't really protected if the phone is stolen.
If the password protection app does use encryption, which encryption algorithm is used? Strong encryption algorithms, such as blowfish, have never been broken whereas home-grown encryption algorithms are easy to crack unless the person who wrote the software truly understands encryption.
How exactly do these password protection apps work?
