All applications require you to install Java Runtime, which you can download from java.sun.com
DSI 3ncryp70r:
DSI 3ncryp70r--v. 1.0--A free application designed to provide secure/easy encryption of anything. It can encrypt any file, in any language, with any characters imaginable. Its, perhaps, best usage is for Instant Messaging sensitive data, as it can divide the encrypted text up into blocks of text <800 characters long and then it will automatically select and copy each block individually, so that you just have to move back and forth between the application and the IM window and all that you have to do is paste.
DSI Calci
DSI Calci--v. 1.0--A free application that works similar to any normal RPN logic calculator, only it uses, by default, an "infinite" queue and most functions, such as *+-/ work with all information in the queue, instead of the old way of working with only the top information in the stack. RPN logic dictates that you enter in the numbers and then press the mathematical operation to be performed (2 [enter] 3 +).
DSI N3tworking
DSI N3tWorking--v. 1.1--A free application that was designed to help home users and network administrators alike. It's main purpose is to tell you what the proper IP Addresses and settings are for a given network address and given amount of either hosts/nodes or subnets. It also gives the hexadecimal, binary, and decimal representations of the given network address.
