Tools for understanding other people's code
CODE UNDERSTANDING TOOLS
While working on various tasks in #osint (Open Source Intelligence), sometimes there is a need to quickly understand someone else's code.
For example, when investigating a person's public profile on Github or Bitbucket.
Also, the need to understand other people's code may arise when one wants to modify some of the #opensoure tools for #osint to suit one's needs.
Here is a small selection of online tools to help you do that.
Most of them are free.
You can read a summary of how to work with the different classes of tools in my Twitter thread: https://twitter.com/cyb_detective/status/1508167717928546312
