Ghidra (pronounced Gee-druh[1]) is a free reverse engineering tool developed by the National Security Agency (NSA). It was released at RSA Conference in March 2019.[2] The NSA stated that it plans to release Ghidra as open source in the "coming future".[3] Ghidra is seen by many security researchers as a competitor to IDA Pro and JEB Decompiler.[3] The software is written in Java using the Swing framework for the GUI. The decompiler component is written in C++. Ghidra uses Jython so plugins can be developed in Python.[citation needed]

Ghidra's existence was originally (though not legally) revealed to the public via WikiLeaks in March of 2017[4], but the software itself remained unavailable until its declassification and official release two years later.[2]
