I previously made two rot13 DejaVu fonts (Rot13 DejaVu Sans and Rot13 DejaVu Serif) so I thought I might as well make fonts for the other less-widely used rot_n ciphers. When I say “DejaVu” I mean it is based on the public domain DejaVu fonts. These are by no way official DejaVu fonts. I claim no copyright on these fonts because all I did was rearrange glyphs from the DejaVu fonts, which is nothing compared to the work put into the official fonts themselves. As with all the rot_n ciphers, encoding them twice (ie. using the rot47 font to view rot47 encoded text) will result in the unciphered text. It’s a cipher that decodes what it encodes by doing the same rotations. The example pages require a modern browser that supports webfonts, such as Firefox 3.1 beta or Safari 3.1.2.

I found myself wondering how to rot13 cipher text in a web browser without JavaScript or server-side interaction. I then came up with this idea, rot13 fonts. I have made rot13 equivalents for 2 DejaVu fonts, Sans and Serif. I only have the fonts use the rot13 affected characters, a-z; A-Z, Unicode ranges: U+0041-005a, U+0061-007a. This is so it would be more suitable for web use because the DejaVu fonts are 500KB+ each. The rot13 fonts are 12kb to 14kb large.

You can test these fonts to view “Uryyb Jbeyq!” (rot13 “Hello World!”) at this test page. The test page requires Firefox 3.1+ or Safari 3.1+ or for both Rot13 DejaVu Sans and Serif to be installed on your computer.

The fonts are available for download here.

Rot47 DejaVu fonts may be added when I get the time.

I haven’t written a post in a while so I’ll write one now. I have abandoned the Mibbit IRC Form project because Mibbit has gotten it’s own form for creating widgets. I have also added a rot13 and rot47 encoding bookmarklets to the JavaScript Bookmarklets made by me list. Rot13 and rot47 rotate the characters in text 13 (a-z, A-Z only) or 47 (all of ASCII) characters backwords. Encoding rot13 or rot47 encoded text again is the same as decoding it. › Continue reading
