3. strong your algorithm is it is worthless if you don t protect the password Encrypt it uses several steps to make sure that the key is secure 1 When you enter the password it is not used straight in the algorithm Instead it is converted into a highly uniform binary sequence using the SHA one way hash function see Algorithms This way even if you use a simple password like NikonF5 it is scrambled At the conversion all 256 possible ASCII characters are used at the same probability to make the key More secure 2 The password and key are never stored in the header of the files 3 There are some file specific bytes added to the password like file size file date and then they are processed through the SHA together This way even if you use the same password for all of your files the final encryption key will be totally different for the individual files This makes the job of a potentional hacker extremely hard 4 If the Caps lock is accidentally on when encrypting you can enter a password by mistake that you won t be able to guess next time Encrypt it detects the state of the Caps lock button and warns you if it is on at the password entry dialog 3 8 Wiping When a file is deleted from your disk by the Epoc machine its content may physically remain on the disk for a while until it is overwritten by another file This way a sophisticated hacker can find portions of the deleted files using a Disk Editor This is why

5. wiping is so important Encrypt it doesn t simply delete the files instead it wipes their contents first then erases them from the disk Dont t worry this entire process only takes less than a second but this way your un encrypted data is physically removed from the disk making the process even more secure A stand alone wiping tool is also included that wipes the entire free space of a disk independent of an encrypt decrypt process 14 3 9 Running twice It is possible to run two copies of Encrypt it at the same time however you can t start these two copies from the Extras bar Do this run the first copy from the Extras bar Now go to the system screen and locate the encrypted file that you want to process and if you press Enter a second copy of Encrypt it is launched with this file This way you can Quick update several documents at the same time while each copy of Encrypt it is waiting in the background NOTE Before this mode works you have to make sure that Enter opens a program twice Go to the system screen press CTRL K for the Preferences and on the bottom select Enter to Open multiple files If you don t want to change this it is fine just remember to press Fn Enter if you want to run Encrypt it twice 4 FINAL NOTES 4 1 History v4 0 New multi tabbed and enhanced interface New function Stand alone wiping tool Correction chance when entering a wrong password Protection against ove
