From the developer: Magic Crypter allows to crypt discretely all type of files (texts, pictures, applications, music ?) so as they can not be viewed or seen by anyone. Moreover, after crypt, the files names are not changed (if you decided to). That make the crypt discrete. For example, when a pictu re has been crypt, there won't be any available preview of it. After crypt, any kind of file will seems to be corrupted. Magic Crypter can be very useful in the following cases: ? Send documents or pictures by email. The recipient will be able to decrypt the files with the password that you will have give to him. ? Crypt on or more files, or a complete directory on your hard drive ? if your computer is connected to a network ( if you work in a company), you will easily lock all you sensible files. ? Using a personal key in Magic Crypter, you will be able to lock files that no hacker can decrypt.
