This contextual menu plugin allows you to encrypt and decrypt text files with a simple cipher known as ROT13.
Installation is easy. Simply drop the "ROT13 CMPlugin 1.01" file on your System Folder and restart the Macintosh. Once you have done that, you're ready to go.
How does the ROT 13 cipher work?
It "shifts" the letters of the alphabet 13 places:
ABCDEFGHIJKLMNOPQRSTUVWXYZ
becomes:
NOPQRSTUVWXYZABCDEFGHIJKLM
And
Wreck a nice beach.
becomes:
Jerpx n avpr ornpu.
ROT13 is a very simple cipher- it's not secure enough to encypt trade secrets, but is more than enough to keep your little brother from reading your diary. Think of it as a gibberish-english, english-gibberish dictonary.
Since it shifts the 26 letters of the alphabet 13 places, it's very easy to use- the same method used for encoding with ROT13 is used for decoding it. So if you have a ROT13 file, running ROT13 on it again renders it readable.
Simply select a text file in the Finder, and control-click on it. You will see the contextual menu for the finder- select the item "ROT13". The file will be instantly transformed into a ROT13 encoded file. To decode it, simply do that all over again.
