MixIt is a crypting program which makes given data unreadable using mixing, shifting, coding etc.
MixIt 1.2 offers you some features for an unbreakable communication via email using one time pads and password books.
To protect data, MixIt mixes a given input file with various mixing and shifting algorithms. To do so, MixIt needs a password and a level. To deprotect the mixed data, you must specify the password and level. This is like using WinZip or other archivers which can protect data too. This is made to protect data on your local disk.
To exchange such protected data MixIt offers password books which must be owned by both partners who want to exchange data. To exchange password books, MixIt offers file locking functions that can be used with the Diffie Hellman Box Model.
Like exchanging huge password books using one time pads, MixIt can create password books with random one time pads that one can lock data with these one time pads. You need the Diffie Hellman Box Model only to exchange these password books. The next messages can be simply send to your partner.
