Python implementation example of cracking email account password

This article mainly introduces the function of Python to implement online brute force cracking of email account passwords. It combines a complete example to analyze the relevant verification and cracking operation skills of Python reading txt dictionary files for email. Friends in need can refer to the following

The example in this article describes how Python implements the online brute force cracking of email account passwords. Share it with everyone for your reference, the details are as follows:

dic dictionary format is as follows (mail.txt):

username@gmail.com:password
username@gmail.com:password
username@gmail.com:password

and so on, remember to save it as utf -8 encoding format.

Place it in the current script directory, or you can define and modify it yourself.

Support ssl https/imap protocol.
