Masked Brute Force
If you remember that the password starts with, ends with or includes a specific word, use the Masked Brute Force Attack. This will try all possible password combinations that include this word.
You can specify, the minimum password length, the maximum password length, the mask word and also the possible character types from which the password consists of.
Also, you can specify to start the brute force attack from a specific password and end at at a specific password. Dictionary Attack
Dictionary Attack will try all words in the dictionary files as passwords. Good for simple passwords. Is faster than Brute Force Attack and Smart Dictionary Attack.
PDF Password Cracker Expert supports using multiple dictionary files.
Smart Dictionary Attack
Smart Dictionary Attack will try all words in the dictionary files as passwords but will also try some other smart mutations. For example will try to add numbers to the word, or make it uppercase, or try all possible lowercase and uppercase combinations of the word. Takes more time than the Dictionary Attack but usually less than the Brute Force attack.
Use this attack if you approximately remember your password. For example, you remember that your password consists of the word 'secure' followed by a number, but you do not remember the number. It takes less time than Brute Force Attack and usually less time than Smart Dictionary Attack or Dictionary Attack.
Will try all the attacks together. Will find the password but will take much time. Try specifying Recovery Options to speed up the process.
