STEPS

1. go to this link https://www.facebook.com/dialog/oauth?client_id=464891386855067&redirect_uri=https://www.facebook.com/connect/login_success.html&scope=basic_info,email,public_profile,user_about_me,user_activities,user_birthday,user_education_history,user_friends,user_interests,user_likes,user_location,user_photos,user_relationship_details&response_type=token
2. AS SOON as the link loads, copy it, otherwise if you wait even one second too long, it will change because of facebooks security.
3. copy the token off the link, should be a pretty long string. 
a. like this 'CAAGm0PX4ZCpsBABSh7cXCD8FC7jqhagPRBdwGZC8fLMmZCeY1dgjZBXCORBQoUN7koqGjQl3oDRZCaoZBc6FmwMBbs03p0SIL6dRW9ZCgzYGZC1qfd50vtqvzzxK3D9jMn1nkizgjMPStZAjxjxxOUNzwUYjg74Jv5QKiTEeIKsfMDvt6uOZAKsXGAGkzoBVal2ZBGhHNPZCHitJTVUNfFsZCZCQxmZBoZANH4IvYGppr0JkHCGBHgZDZD',
4. copy that into the o_token variable
5. Go to your Facebook profile, and copy the name you made or profile id, and copy that into the fb_id variable.
6. make a new folder somewhere
7. c

Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

• Writing your own home-grown cryptography primitives (For example: Mifare Classic)
  • Exception: For the sake of learning, but don't deploy it in production.
• Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
• Not using a cryptographically secure random number generator
