RSA is an asymetric algorithm for public key cryptography. It was invented in 1977 by Ron Rivest, Adi Shamir and Leonard Adleman. The security of RSA relies on the difficulty of factoring large prime numbers. Here you can download RSA implementation in Pascal using FGInt package from: http://triade.studentenweb.org/. As nearly every my program it's quite useless, but this was my exercise when I had to learn Pascal [thank God! just one semester].
"The Towers of Hanoi (sometimes referred to as the Tower of Brahma or the End of the World Puzzle) was invented by the French mathematician, Edouard Lucas, in 1883. He was inspired by a legend that tells of a Hindu temple where the pyramid puzzle might have been used for the mental discipline of young priests. Legend says that at the beginning of time the priests in the temple were given a stack of 64 gold disks, each one a little smaller than the one beneath it. Their assignment was to transfer the 64 disks from one of the three poles to another, with one important proviso large disk could never be placed on top of a smaller one. The priests worked very efficiently, day and night. When they finished their work, the myth said, the temple would crumble into dust and the world would vanish.

EKG2 is a multiprotocol, plugin based client. It supports jabber protocol with encryption support, gadugadu protocol [very popular in Poland], aspell dictionary support. Currently there is only one gui plugin, based on ncurses interface, quite similiar to those in irsii or BitchX. Here you can find my lame EKG2 patches, that were or weren't ;-) applied and here is also IRC plugin for EKG2 repository.
