If you usually store private files and documents in your PDA and you want to keep them safe from other people, there is a simple and easy way to protect them: visCrypt.
visCrypt is a lite application that allows us to protect our files in three different ways:
Hiding them into pictures: You only have to choose a picture and set a password. The file will seem to be a picture but when you press tap certain places in the picture, the document appears.Password protection: This is the common procedure. protect your file with a password. Only people knowing that password will access the file.PIN: This latest choice allows you to encode the file under a PIN code, like the SIM card of your mobile phone.
In short, visCrypt is a very goo way to protect your files on the go. Remember that those files must be stored in My documents folder.
