Firefox extension: Leet Key

Today while looking for a ROT13 [en|de]coder extension for Firefox, I found Leet Key. It has several useful features: you can enable it while typing in a textfield, and it will automatically convert your keystrokes to any supported encoding. Likewise, you can highlight text on a webpage and convert it to any encoding.
But get this: among the supported encodings (which include ROT13, hex, bin, Morse code, Base64, Dvorak, and more), you can also encode and decode leet (as the extension title suggests). So now you can look like a lamer without actually spending all that time finding the right numbers and symbols to substitute into your writing! You write like a normal human being, and Leet Key translates your typing into something that looks like it was written by a 13-year-old smacktard! Plus, you can finally figure out what all the 5(r1p7 k1dd13 lusers are saying without having to spend ten minutes analyzing the paragraph!
Sample output:
- Plain text:
- The quick brown fox jumped over the lazy dog.
- ROT13:
- Gur dhvpx oebja sbk whzcrq bire gur ynml qbt.
- L337:
- 7h3 qu1(k 8r0wn f0x jump3d 0v3r 7h3 |4zy d06.
- Morse:
- - …. . –.- ..- .. -.-. -.- -… .-. — .– -. ..-. — -..- .— ..- — .–. . -.. — …- . .-. - …. . .-.. .- –.. -.– -.. — –. .-.-.-
You get the idea. The L337 decoder is far from perfect (it’s not as flexible as it could be, not recognizing many of the nigh-infinite variants of leet lameness), but it can make life easier and give you a better cover when carrying out sorties in illiter moron hostile territory. (Xanga comes to mind…)
