- I found a bunch of text files on a couple of my ROM DISCS and
- discovered that they where encrypted in somthing called ROT13. It's
- realy not that complicated but if you had to sit there and write it
- all out, it would take you a year, so I wrote this program in
- assembly language. This program will encrypt as well as unencrypt.
- It's output file is ROT13.REN. You should rename this file because
- it's the only name my program will write to and it will be overwriten
- if you execute the program again after creating it. It appears to be
- able to handle any size text file. I tried it on a 20 meg (combined
- of course) text file, it took about 45 seconds. It processes 30k
- blocks at a time. I did'nt bother to allocate memory. The program
- is'nt worth that much time and I fiddled enough with it any way. If
- you want one that will handle larger blocks so that it operates
- faster just leave a note or somthing and I'll get back to you. This
- is an updated version v 1.31. It now encrypts .EXE .COM .GIF and
- many other files and programs. I'd like to say it will encrypt any
- file, well I guess it will but you might not get it back, but I've
- only run it on .EXE .COM .GIF and a few misc programs and then undid
- them. It worked fine.
