Radare2 overview
Radare2 is a reverse engineering framework build by "Pancake" and all the people contributing code on the public github repo. Radare2 is a second version of a project called "Radare" which was created in 2006 by "Pancake" for the purpose of creating a simple hexadecimal editor with support for searching patterns and dumping the search results to disk to recover some PHP files deleted from an HFS partition. Because of that, Radare stands for RAw DAta REcovery.
