File Encryption Include File

[Guest Guidosoft]

http://www.autoitscript.com/fileman/users/public/Guidosoft/ - the script is on that crapy web page. I will be making new versions.

With this script you can easily encrypt strings using currently 3 different methods but later version will have more control over these methods and much more encryptions.

If you need a more secure encryption, I suggest you combine a bunch of them into an algorithim, a single encryption.

However, you yourself must process the files if you want to encrypt a file. You have to read the string and then encrypt it with my include file.

So far I have 3 encryption methods:

Columnar Transposition

Character Substitution

PlainText Table Cordinates

Read the include file comments to learn more.

So what do you think.

Will this be of any help to any of you??? I will be posting an example soon.

Here is a quick example. It requires the GUI version of AutoIt however. This paticular script, shows an example of a week encryption however.
