It will keep all your passwords safe and sound and only you have quick access to it. The password is easy to remember but also strong at the same time. The device will never be online or connected to any network so it will stay uncurrupted. No way for anybody to install a keylogger or break your PC firewall. You can also generate keys for other software like for hard drive encryption tools. Send crypted notes to a friend and nobody will be able to hack this communication. The device it self can store up to 7 notes each with 128 characters. HOW TO USE 1) choose "enter passwort" and enter 16 passwort keys by pressing buttons. Each of this key records will be started by pressing and holding the first button of your key, after that you can let other buttons follow, up to 6 characters in total. If you release all buttons the key is finished and you can start entering the next key. Already filling in 2 times a key with 6 buttons, 2 times a key with 5 buttons and at least 4 more keys with just 2 buttons lengths will give you a well security level. You not have to enter full length inputs to all 16 key elements. 2) go to "open notes" choose "1" and press down button. Press 15 times the B button to format that note empty. 3) now you can entering any text by using the B key to open and choose any character from the virtual keyboard, using the arrows to move to another position inside the 16x8 sized note. You have 61 different characters also including empty ones. Its not an securtity problem using points, and empty spaces inside your text. 4) use A button to close your note. Your note is now already encrypted with the password you entered before. 5) now you can watch how the note looks encrpted by opening "open notes source" and choose your note nr.1 again. Press A button to go back to the main menue after. 6) go to "erase password" and pressing B & UP & RIGHT button at the same time. Now your note cannot be uncrypted by anyone dosnt know your password. Turn the SAS device off it will keep your note save and crypted on its memory. 7) turn the SAS device on again. 8) try to open it without entering a passwort by choosing "open notes". You will see only scrambled characters, theres no way to read your note that way. 9) go back to main menue and open "enter password" and enter your password. After that you can open, view and edit your note as usual. If the space of one note is not enough you can use others of the 7 notes with the same or different passwords. You may use a different passwords but by security reasons you not have to do that. HOW TO USE "KEYGEN" 1) entering a passwort 2) go to "keygen" you will see 4 lines, each with 16 charackters. You can use them in every way you like for example for a hard disc encryption. 3) after using it please dont forget to erase your passwort. SHARING NOTES WITH A FRIEND 1) go to "open notes source" choose your note number and make a photo of that screen. You can use your handy and the internet to share it with a friend or a group of friends. Its encrypted and cannot be readed. Only the passwort you have to share with your friends safely before like at a moment you meeting each other in real life. 2) your friends have to go to "open notes source" press down key before to format that note. Then they can enter the characters as the photo you send them on their device. 3) after on they can enter the same passwort you used too, and go to "open notes" to uncrypt and edit it. VIEW KEY you can enter the key menue to view your key and cancel the menue by pressing A button without entering or deleting your key. STAY SAFE -"erase passwort" before turning your device off or before leaving it unattended -if you forget to turn your device off it will erase the entered passwort after around 10 Minutes. The green LED will turn on in that case. -dont connect your device to computers, only use direct usb power chargers to charge it. -note: The encoding process is content relevant, every small modification of the source text will result in a complete different output same as every modified key element. -please use different buttons and nothing like, Up Up Up Up, Up Up, Up Up. Up Up Up etc. -You only need to hold one button during entering sequence. This button can change during input, for example you can enter combinations like: UP, DOWN ( holding down button and release up button), LEFT, UP etc... -my advise is to use the following key length for safe encryption: 2x6 buttons + 2x5 buttons 4x2 buttons which will result in about 4,00E+21 key variations if tha attacker knows where are the long keys placed and he didnt know it. In real its a lot more combinations any attacker have to brute force to hack your key. -or use the following length for ultra safe encryption: 3x6 buttons + 3x5 buttons 5x2 buttons which will result in about 8,45E+30 key variations -The safety of your entered password is shown by the blue LED light, if it starts blinking you reached standard safety. If it reaches ultra safety it will stay in solid blue. -Background: The core of this programm is what I call arrowKey by using 6 different buttons, 6 following each other, you can reach 6x5x5x5x5x5 combinations by using the full length, thats 18750 possible combinations for one key. Any attacker dont know which ones are long elements so the combinations he have to bruteforce getting unbelievable high. One other thing is by replacing content elements with each other and making the encryption content relevant so the full uncryption process have to be done before the results can be proved. So every attempt to uncrypt by force will fail if the passwort strength is like suggested. Thats why the SAS device needs about 1 second to uncrypt it even if its just 128 characters. They content gets altered and replaced / encrypted again and again in an compley way. PRICE TO CRACK IT -there will be a contest to uncrypt a crpted note without knowing the passwort. -this contest and feedback by other programmers and hackers should try to help and figure out the true safety of this programm and improve it if necessary. CHALLENGE 1 Very week key: Key with 1x6 buttons, 1x5, 1x4 and 1x3 and 4x2. The unused 8 keys are once pressed "B" buttons. Where the "A"s located inside the key and the real password keys is unknown. The text is plain text without taking care about encryption, spaces, "." etc used. And more as the half of 128 characters used for it. The rest are " " blank characters.
