MD5 is used here as a security program, you do not need it in order to use any of the files that you can download here.
At long last, people are becoming more aware of the security threats on the Internet. I have taken the time to provide some simple security features that should allow you more peace of mind when downloading things from this site.
With regard to point 1, my machine is in one place on this planet and is only accessible from the Internet when I am online. To protect against attack whilst I am online, I use a firewall. Points 2 and 4 occur only for a short period of time therefore there is not a great deal of opportunity for an attack whilst these points happen. Point 5 is really up to you. This leaves Point 3 as the main opportunity for attack.
No matter how good the protection is on a server, people can still break in and therefore, I have added a few features to the pages on this site that lead to a download. There are:
These are intended as security devices, depending upon the level of security you really want. A typical example is . . .
However, this is not entirely secure as:
In response to this:
These points also address the problems of intercepting and substituting traffic on the way to and from servers (points 2 and 4) as all traffic would have to be interecepted and changed in a consistent manner.
To use the MD5 program in MS Windows 95 or later, open two copys of Windows Explorer and make sure that in one of them, there is the copy of MD5 and in the other, the program you wish to generate the hash from. Drag the file over the MD5.EXE program and drop it (on it, otherwise you may just move the file to the same directory as the MD5.EXE program). The program will run and if you have the DOS box set so that it will stay open after it has run, you will be able to see the hash. Compare this to the one on the web page and if it is the same, you know that the file you have is the same as the one that I uploaded (or at least that it is extremely unlikely that it is not). If the hash is different, it could be caused by a number of innocent reasons such as an error in the file transfer. If this happens, make a note of the hash you got and try downloading the file again. If you get the same hash, let me know about it immediately by sending e-mail to paul-grosse at ntlworld dot com , telling me the name of the file you were downloading, the hash value you got and the page you got the different hash value from. Occasionally, I update files and you may be that one in a million download that picked up a hash and a file that didn't match.
For those of you who want a file sent as an e-mail attachment, I can do that. If you really want to be secure, I can provide you with a PGP signed copy of the MD5 hash if you want it or even encrypt it or the whole file for you. My PGP key link is in the menu at the top left of this page.
