This program is a tool for creating and working with regular expressions. You can type your regexps in and see them match the data real time, as well as see a list of all the matches found by the pattern. You can use this to help develop efficient and working regular expressions for your programs without having to spend lots of extra time debugging the expressions from inside a program. Updated Version: Added ability to save expressions and recall them later. Also added the ability to turn off live matching to prevent slowdowns with very large patterns or data.

made this out of boredom when a person was worried about storing their users' passwords as MD5 hashes in a database due to the recent collision in the algorithm. I thought he was being overparanoid so I wanted to see how fast the password I use could be brute forced. I tried a few similar programs but they didn't perform as fast as I thought they would, so I decided to implement a cracker of my own in C. To my satisfaction it was much faster than many I found, although I don't think this is anything close to the best, in fact I think brute forcing any type of hashed password is a waste of time. This program is able to hash and compare about 120,000 passwords per second on my P4 2.6 ghZ processor. Fixed threading to work on Win95/98. Some other benchmarks included in zip file.

A program for managing mãìlìng lìsts collected by øpt-ìn førms ør spìdérìng méthøds. If you have a måîlîng lîst that may contain dùplïcãtës, malformed êmåîl åddrêssês, or you wish to filter the list based on keywords, this program will do all that for you. With 3 built in functions to remove dùpës, filter out user-defined keywords, and validate the äddrèssès in the list for proper format. You can also sort the list if you wish. Runs very fast. Using a list of 1.4 million address on a P4 2.6 Ghz cpu it loads the list in 8 seconds, validates format in 7 seconds, removed 68,000 dùplïcãtës in 35 seconds, and checked each ãddrëss for 10 unique keywords in 45 seconds, and sorts list in 14 seconds.

This program helps construct HTTP requests to send to a webserver to retrieve webpages. Fill in the hostname, port, and file, along with any additional headers you would like to send and it constructs the request and then sends it, showing you the response headers and response body. Supports get, post, and head methods. Useful for debugging requests or just learning how HTTP protocol works. Updated Aug 2 05, fixed some memory allocation problems that caused crashes. Written in C for Windows, source code included.
