Today, I will talk to you about how to use Python to crack the compressed package encrypted by colleagues. Many people may not know much about it. In order to let everyone know more, Xiaobian summarized the following contents for everyone. I hope you can gain something according to this article.

Here's what happened:

Milk tea again, okay.

Let's get to work, get this done before Dave gets back.

David says it's a six-digit code.

Then we can generate all six digit passwords using python

#Generate password tables from 000000 to 99999 f = open ('passdict.txt ',' w') for id in range(100000): password = str(id).zfill(6)+'\n' f.write(password)f.close()

In this way, we generate a password table from 000000 to 99999.

And save them to the passdict.txt file.

The 6-digit password table is so big!!!

What's next?

nature is to traverse the passwords in the generated password table,

Brute force cracking!

Popular science time:

zipFile Modular Python comes with modules that provide zip file creation, reading, writing, appending, decompression, and file list operations

extract all (path=None, members=None, pwd=None)

path: Specify the location of the extracted file

members: (optional) Specifies the files to be extracted from the Zip file, the file name must be a subset of the list returned by the namelist() method

pwd: Specify the Zip file decompression password

Then we can use zipFile module to traverse the password table,

Try password by password to see if you can open the compressed package.

until success.

Import zipFile

import zipfiledef extractFile (zipFile, password): try: zipFile.extractall (pwd= bytes(password, "utf8" )) print ("Dawei's compressed package password is" + password) #crack successfully except: pass #fail, skip def main(): zipFile = zipfile.ZipFile ('Dawei. zip') PwdLists = open ('passdict.txt ') #Read all passwords for line in PwdLists.readlines(): #Write passwords one by one Pwd = line.strip ('\n') guess = extractFile(zipFile, Pwd)if __name__ == '__main__': main()

took less than a minute

The password successfully solved is:

Close

Before Dawei came back,

A few more words.

Dawei only set a 6-digit password,

So this time as long as the single-thread violence traversal is ok.

And if there are more digits,

A complex combination of alphanumeric characters?

We can apply multithreaded process decompression to speed things up

There are also brute-force dictionaries on the web,

can be downloaded and used to traverse

Interested friends may wish to try.

David's back.

I told him the password was the date of the compressed packet.

David said: 20191119 He has tried.

However, the compression time of this compressed package was 20191118 the day before.

You keep saying you'll use today's date, but why try today's 1119?

But the milk tea is quite good ~
