Brute force actually means to start with a letter a and encrypting it. Then see if the encrypted strings match. If not then b, c, … until we’ve gotten to admin. Then the encrypted strings will match and we’ll know that is the right password. Brute force attack is the slowest method of cracking, but there is no risk that you’ll not find the password. The thing about brute force is that the time of cracking rises rapidly depending on how long the password is, how many characters are being used in it and so forth.
