Project

 * Slavishly following the latest Wikipedia fad, User:Matt Crypto created a Wikiportal/Cryptography, one potential "start page" for cryptography on the Wikipedia, somewhat similar in style to the Wikipedia Main Page. Amongst other things, the page includes a crypto featured article, a "Did you know" section and a some news items in cryptography.
 * On Talk:Steganography, there is a long-standing challenge to see if anyone can discover an easter egg hidden in an image on Wikipedia. This month, Tim Chambers provided a hint: "It's in Ppeak-s.jpg. That was a few years ago, and I've forgotten exactly how I did it. But I know it was some package I found via Google. I did not encrypt the message. Discovery of the package (and the hidden message) is left as an exercise for the reader. <>< tbc 05:48, 10 Mar 2005 (UTC)''"

New participants
This month, three users have added themselves to the Cryptography WikiProject list:
 * User:Julian Krause, who describes himself as a "Computer Science Major, interested in all types of cryptography and math."
 * User:ArnoldReinhold &mdash; not so new, of course ;-)
 * User:Vesta (Levi), who notes that he is "CS also, computer security-related, can also make images and diagrams."

WikiReader Cryptography
One article slated for the WikiReader in Cryptography is Caesar cipher, which was promoted to Featured Article status this month; see Featured article candidates/Caesar cipher. The article was accepted on 31 March with 6 support votes.
