  Special EXE Password Protector  -  Version  1.01

Sometimes it is really necessary to protect your application against start-up by third person. Just imagine: you work on your computer at home, but the computer is also used by other family members. Situation, that your child turns on computer, starts up your application, and destroys all your work, can happen really easily. The same can possibly happen in your office when one of your colleagues uses your computer. SEPP is suitable for standard users who need to protect some applications against unauthorized start- ups. But it can be also used by professionals for sending sensitive applications via e-mail (e.g. software developers can protect their beta versions) or system administrators can protect some applications against their start up by standard users. It will be very helpful for I-net cafe providers in case they want to restrict starting up some applications by their customers. For the protection there is used really strong encryption algorithm AES (known as Rijndael) in SEPP. SEPP uses cryptography of 256-bites length which is currently unbreakable. If there had been used more than 1 million computers for breaking one key, it would have taken longer than lifetime of anybody on earth to brake it. Although there is used such a strong encryption, the time for start up of protected application is just slightly extended, since SEPP has been programmed in Assembler and AES algorithm is very fast. Of course, all depends also on speed of the processor where the protected application is run. The protected application is encrypted with symmetrical encryption algorithm AES (Rijndael) and wrapped by "envelope". After start up of protected application, this "envelope" runs the window for entering the correct password. If the wrong key is entered, application will not be correctly decrypted and will not start-up. Application will start up successfully only when the correct password is entered.
