The password cannot be patched out as it is used to decrypt the archive's content. Check Wikipedia on algorithms like AES.

hummm when u enter the password .... what happen? 7z uncrypt everything and open the file? if it so .... u cant jump 7z the uncription time?

[hezz]

kazilmar, you don't understand...

the files inside the archive get encrypted with the password as key.

if you don't have the password, the files can't be unencrypted.

[kazilmar]

so u think it impossible to make the program think that i have enter the good key?

You can make it think whatever you want, the fact is the data is encrypted with a key and without entering the correct key you can't decrypt the file. AFAIK there is no "master key" that will allow you to decrypt the files. Like metr0 said read the wiki on AES encryption to understand how it works.

if i understand .... if im able to make the prob think i enter the good password, it dont work cause encryption try to uncrypt witout the good password?

so the only alternative i got is to brute force or fishing the password with the algoritme?

I think you can find the password just by brute force.
