More Information:

The following program was written to give users more security when checking for Leaked passwords. It takes in a list of passwords the user would like to check for, and creates a utf-8 hash of the password. It then sends the first 5 digites of this hash to an API. The said API then returns sets of the hashes that match the sent query along with a count of how many times that password has been leaked. This program then compares that with the remaining hash that wasn't sent and reports to the user the amount of times their password has been leaked.

In order to check for leaked passwords, the user must modify the PASSWORDS list. It is recommended that the user also delete their passwords from said list after the program has finished to ensure optimal security.
