How Does It Works ?

To get a user email, osingt is checking :

• all the public commits of the user, if the email is not hidden in one of the commit it will be added to the list
• if the user have a GPG key, if he has one, it’s getting the email from the content of the GPG after a base64 decode
• github user API

To get a user email, osgint is checking :

• github user API
• spoofing a commit with the email, then checking the name in the commit history (working every time) (Work In Progress)
