MD5 brute-force cracking program (Python)

Yesterday, an MD5 brute force cracking tool was installed in Python due to a hand mark.

 

In the duration, the method for calculating the n times of the string is optimized, and version 0.2 is implemented.

 

Then I found that the generated sequence had some problems, so I switched back to v0.1 and then improved it. Low efficiency.

 

The maximum latency of the single-object string on my Intel Core Duo t6670 is 5 W string/sec

 

It is really sad that I wanted to use multiple programming threads to discover Python fake multi-programming.

 

Okay. The next generation will give you the desired ones:

I have already done a good job of this kind.

 

However, you need to upload at least one file to start the operation:

CiphertextFile (text, but not end with txt). This text is used to import the object's MD5 password. Each line is 32 bits, and each password is 1 line.

 

Passwordtraveler () is the object of the character string. Use. Next () to convert it to the next string to be modified.

Loger () is a type of log

Config () is used to retrieve and merge the configuration file so that the next time the cursor is retained

Checker () is not to be mentioned anymore. It is to be used to compile logs.

 

This brute-force cracking program downloads 0 ~ 9, ~ Z and ~ Z. If you need to modify it, please understand the number of _ fix () mails in passwordtraveler () and then modify it.

 

Modify once_check = XXXXX.

 

Modify md5_str = md5.new (X. Value (). hexdigest ()

 

Basically. Have your nice time .~ 0.0

 

 

If you do not set config for the first operation, the system will remember the load error. Then, the config. ini will be generated.
