Before Starting off with the practical lectures, let's get an overview of how passwords are stored.

2
00:00:10,610 --> 00:00:14,870
When you set or change a password window, generate a hash and empty.

3
00:00:14,900 --> 00:00:21,530
Hash hashes are stored in security accounts manager database, commonly known as Sam or Sam file.

4
00:00:22,120 --> 00:00:27,500
The hashes are irreversible and you cannot obtain password directly from a hash.

5
00:00:28,390 --> 00:00:34,210
So when logging in, when a user enters passwords, windows, computers, hash, and then compare this

6
00:00:34,210 --> 00:00:36,430
hash with the entry in the same file.

7
00:00:38,560 --> 00:00:41,280
And if both hashes are equal, the user is logged in.

8
00:00:43,480 --> 00:00:49,750
So the tools that we are going to study in this section, when you play this file to crack or bypass

9
00:00:49,750 --> 00:00:50,710
the passwords.
