brute force.

Yeah, you'll need to do a brute force attack on it.

 

[KFatal]

^ yup im doing it right now.. taking some time though.. thx both of u..

 

[Cooper]

it could take days depending on the length of the password and the characters used.

brute force will take you thousands of millions of years to get the pass, unless the pass is only a few characters,so its a waste of time.

if you have one file thats the exact same file inside the rar archive,then you can do a reverse plaintext attack,and you can get the pass in no time.

 

[KFatal]

^ its a rar with 2 files in it

 

[bigmack]

^if u dont got any of the files inside the rar file,then its impossible to get the pass,you cant use bruteforce,unless you have access to thousands and thousands of supercomputers networked.

brute force is doable upto maybe 7 characters
