Ghidra ( ) is a free and open source reverse engineering tool developed by the National Security Agency (NSA) of the United States. The binaries were released at the RSA Conference in March 2019; the source code was published one month later on GitHub. Ghidra is seen by many security researchers as a competitor to IDA Pro. The software is written in Java using the Swing framework for the GUI. The decompiler component is written in C++, and is therefore usable in a stand-alone form.
