LockTite v2.00 Program and File Protector Copyright(c) 1989 by Michael Wegner All rights reserved LockTite 1 ============================================================= LockTite is a file and program protector that's easy to use, requires no special hardware, and it's secure. Although your files or programs are locked, you are still able to copy them (unlike some commercially distributed protection programs), transport them to home or office, where you can unlock the files and continue your work. They even run! Your protected files are turned into executable files which will load and display the following on the screen: ╔══════════════════════════════════╗ ║ ║ ║ This file has been protected by ║ ║ LOCKTITE v2.00 ║ ║ ║ ╚══════════════════════════════════╝ Best of all, LockTite works with any dos file, be it an executable file, a document file, or even a compacted file. LockTite is Shareware. Simply put, this means that I've spent a lot of time writing this program and have no desire to make you spend more for this than necessary. The cost of this would easily double if it became a commercially distributed program. It also means that if you like LockTite and use LockTite, you must pay for LockTite. I've spent quite few dollars for hardware and software just to be able to write programs and utilities such as this, and if I am to continue, I need to be compensated for some of this work. Fortunately, the Shareware concept allows both of us to come out ahead in this deal. Since the distribution is done by you, the user, my only costs besides the above consists of mailing out registered copies to those who pay for them, and giving support for those registered users. As a result, I can hold the cost down to only $12 per copy. Shucks, even I can afford that! You are also authorized, and even requested, to give a copy of this software to friends and upload it to your favorite bulletin boards. You are NOT authorized to charge a fee for this, other than a small cost ($5 or less) to cover copying and mailing fees. If you do pass this on, please include this documentation with the program, and please leave both unchanged. Disclaimer: The author is not responsible for the misuse of this software. Also, although great care was taken in the creation and testing of this program, the author is not responsible for lost or damaged files or any damages that result thereof. NOTICE: This version of LockTite is incompatable with previous/demo versions. If you have files that are protected with a previous version or a demo version of LockTite, you must unlock them with that particular version before locking them with this version. LockTite 2 ============================================================= You should have two files - Lockt200.doc - this file, and Lockt200.exe - the program. Just copy the exe file to any directory or subdirectory you wish, as long as it is included in your PATH statement. This way you can lock any file without having LockTite in your current directory. To run, simply type in LOCKT200 and press the enter key. You will now be looking at the LockTite screen, which looks like this: ╔══════════════════════════════════════════════════════╗ ║ ║ ║ LockTite v2.00 ║ ║ ║ ║ Program and file protector. ║ ║ ║ ║ Copyright(c) 1989 by Michael Wegner ║ ║ Registration no. xxxxxxxxxx ║ ║ Use with extreme caution!! ║ ║ ║ ╚══════════════════════════════════════════════════════╝ <L>ock or <U>nlock? : █ Press either L or U - all other keypresses will be ignored. If you press an L, another prompt will appear: Filename to lock : ████████████ Enter the name of the file you would like to lock. Do NOT enter a path name - you MUST be presently in the same subdirectory as the file you want to lock. There is enough room for a normal 8 character name, a period, and a three character extention. Wildcards (? and *) are NOT allowed. You will the be prompted for a password of your choosing: Enter password (10 characters max) : ███████████ You may enter any password you would like, up to 10 characters long. This password is case-sensitive. A lower case password, such as "test" is NOT the same as "TEST" or "Test". LockTite 3 ============================================================= LockTite then checks the available disk space. If there is enough space for it to work, LockTite will read in your file or program, encrypt it using your password, and then write it out to disk, along with a small header and then deletes your orginal file. The resulting file will have the same name as the original but with an .exe extention and will be 3291 bytes larger. This executable file will load and display the protection notice, but nothing else. Your information is locked tight! You may copy this file, delete it, etc, but without the password, you can't get to the information or program. It's fast and secure. You can even protect it again if you'd like, using the same or different password, making it doubly safe, although this probably won't be necessary. Alternatively, you can give the entire command on the command line of DOS. Just enter the command like this: Lockt200 x filename.ext password Replace the x in the above example with either L or U, depending on whether you are locking or unlocking a file. Separate the parameters with a single space and nothing else. If you make a mistake, LockTite will tell you something is wrong and give you an example command line to follow. Unlocking the file is just the reverse of locking it. The same screens appear asking the same questions, except this time you're prompted for a filename to UNLOCK. Make sure you remember that your file now has .exe for an extention! Use the same password you used to lock it. LockTite will again check for free disk space, decrypt the file using your password, and then delete the protected file. You'll notice that your original filename extention is now back in place. Don't worry about using the wrong password to unprotect your file - LockTite can tell if it's unprotecting your file incorrectly and will tell you so by beeping loudly and stopping the unprotect operation. LockTite 4 ============================================================= Registration entitles you to the following: Free support, either by phone or mail. If you're having trouble running this program, or have questions about it, I will do my best to help you out. I use the word I, because this is a family operation. You won't get an answering machine, an operator, or a form letter. You won't be passed on to the "technicians" or some other nameless soul. I get my paycheck from you and I will support you. Plain and simple. The latest copy of LockTite. This will be your registered copy, which will not have a "beg" screen, but will include the latest enhancements. Disaster Insurance. The cost for this service is $5 per disaster. If you forget your password, fill out a copy of the Disaster Form included in this package, copy your locked file to a MS-DOS or PC-DOS 360K format 5 1/4" disk and mail it to me with the $5. I will unlock your file and return it to you re-locked using the registration number found on the main screen of your copy of LockTite. Please note that because of security reasons, I cannot offer this service unless you have previously registered and are using a registered copy of LockTite. This is basically a free service to registered users, as the $5 only covers my cost of shipping and handling. If you request, I will return your file to you via registered mail. Certificates will be kept on file, thereby protecting both of us. Notification of the latest updates to LockTite and the chance to purchase them at a discount. You will also be notified of other programs available from me. These are normally also offered at a discount, although I cannot guarantee this. I do, however, remember my customers and help out as I can. My deepest sincere thanks to you. In case you haven't noticed, I take this business personally. You, the customer, are never forgotten, and are foremost on my mind. Without you, this little home-grown business would not exist. Special note to sysops: If you currently are running a bulleting board system and would like to use LockTite as part of your system, you are entitled to a discount of 25%. Please include the requested information on the registration form and pay only $9. LockTite 5 ============================================================= Special note to businesses: If you would like information on site licenses, please call or write. I am able to pass on substantial savings to you. Special note to everybody: A couple of things should be mentioned here. First of all, several people have written asking how secure this program can really be if I'm able to offer "Disaster Insurance". To put it bluntly, it's quite secure. To my knowledge, there is no security program on the market today that cannot be broken, LockTite being no exception. However, the time involved in breaking this code would be quite substantial. To help make it even more secure, different algorithms are used in the registered version and the demo version. Both are secure, but the unregistered version will NOT unlock files locked with the registered version, and vice versa. Since those who spend their time trying to break the code will probably not register their copy anyway, your files are even more secure. Of course, the "Disaster Form" that you fill out is, as mentioned above, kept in a secure file for your protection as well as mine. Secondly, this version of LockTite incorporates several enhancements over the original version. These were ideas and suggestions submitted by people just like you. If you have suggestions or comments, don't hesitate to call or write. If it's feasable and useful, it will be incorporated in the next version. Thirdly, LockTite creates a locked file with .exe for an extention, and conversly, creates a file with the original extention when the file is unlocked. If a file by that name already exists, you will be prompted, and have the choice of continuing or stopping the operations. For example: You have two files in your directory: Game.exe Game.doc If you were to lock Game.doc, LockTite would try to create a file called Game.exe, which would be the locked copy of Game.doc. However, Game.exe already exists. You would be prompted and, if you continue, both Game.doc and Game.exe would cease to exist. Game.exe would be replaced with the locked copy of Game.doc, now named Game.exe. The reverse of this is true when unlocking a file. If you run into a case such as this and do not want Game.exe deleted, simply renaim Game.doc to something else, such as Games.doc. LockTite 6 ============================================================= Finally, the "Disaster Insurance" needs a little further reminder. When I unlock your file, it will be returned to you locked, using your registration number as a password. DO NOT make copies of your registered copy and pass them around. All registration numbers are unique. Of course, please make a backup copy for yourself. I will not replace registered copies if you accidentally delete or otherwise destroy your copy with another copy with the same registration number. Also, please note that you MUST be using a registered copy to take advantage of this service. DO NOT send in a "Disaster Form" for a file locked with an unregistered version of LockTite. I will return the disk to you and keep the $5, since the cost to me is the same whether or not I unlock the file, and I cannot lock the file with a unique registration number if you don't have one. Of course, if you have questions concerning the demo (unregistered version) while trying it out, call or write and I'll still assist you with your questions. Fair enough? As I mentioned above, this is a family operation. I do the programming, documentation, and provide support to you. My wife and kids provide support for me and put up with me while I spend time doing this when I should be spending time with them. For this, I'd like to thank them here - Thank you Camille, Dustin and Bonnie. If it weren't for the three of you, I wouldn't be able to do any of this.
