Rot is just character replacement isn't it? :\

iago

Yes, you rotate each character

*laugh*

I see. How does it need a key if it's a static rotation?

Congratulations iago, you just wasted several seconds of my time. I haven't told anybody, so they'll probably waste their time too.

I meant in general.  In this case the key is 13, and everybody knows that, so it's useless.

It's encode! :)
en·crypt   Audio pronunciation of "encrypt" ( P )  Pronunciation Key  (n-krpt)
tr.v. en·crypt·ed, en·crypt·ing, en·crypts

   1. To put into code or cipher.
   2. Computer Science. To alter (a file, for example) using a secret code so as to be unintelligible to unauthorized parties.


en·code   Audio pronunciation of "encode" ( P )  Pronunciation Key  (n-kd)
tr.v. en·cod·ed, en·cod·ing, en·codes

   1. To put (a message, for example) into code.
   2. Computer Science. To format (electronic data) according to a standard format.
   3. Genetics. To specify the genetic code for (a protein molecule, for example).


They are entirely interchangeable.

That's not a pure computer science reference, which is on what terms we're speaking of encode/encrypt.

iago's right, they are NOT interchangeable. Look at these two definitions (provided by yourself):

Encrypt:
Quote2. Computer Science. To alter (a file, for example) using a secret code so as to be unintelligible to unauthorized parties.

Encode:
Quote2. Computer Science. To format (electronic data) according to a standard format.

Those are NOT interchangeable. The PURE purpose of encryption is mass distortion of text in order to HIDE the meaning of it from everyone but its meant recipient. Encoding is to put something into a standard format, such as Base64. Encoding is NOT made to hide its contents from readers.

That's correct.  Rotation encoding has a secret code (in my signature, it's 13), and it perfect fits the definition for encrypt. 

I think that the differences are settled enough that I can make fun of anybody who gets them mixed up. 

All that's left now is to drive into people's heads the difference between DOS and a Command Prompt (cmd) :-)

Question: What's the difference between ROT13 and ROT1 for example?
And to decode ROT13 encoding, you set A=26, B=25, C=24.... and so on, right?

Edit:
To clary on the rot13 thing, and then change the number to the actual letter in the alphabet
So something would be

LOL in ROT13

12, 15, 12

LOL in plaintext
[17:42:21.609] <Ergot> Kutsuju you're girlfrieds pussy must be a 403 error for you
[17:42:25.585] <Ergot> FORBIDDEN

<iago> He is unarmed
<Hitmen> he has no arms?!

on AIM with a drunk mythix:
(00:50:05) Mythix: Deadly
(00:50:11) Mythix: I'm going to fuck that red dot out of your head.
(00:50:15) Mythix: with my nine

ROT13 is a standard format as well, because you are moving EVERY initial value by 13, and your signature is also electronic data.
