Zip nonviolent hack

Everyone is familiar with the zip hack should be a brute force, brute force crack has great limitations, if the password is very long and complex you will probably never be able to decipher. Because today to crack their own previously encrypted zip file, I set the password habitually long and complex, decisive abandon brute force hack, find an article on the Internet http://bbs.csdn.net/topics/10444536, I know there is another way to crack, If you have any of the files in the encryption package, generally we can view the file name and CRC32 according to WinRAR, if you have one of the files, we can calculate the CRC32 you own the file, if the two are the same, basically can be judged to be the same file, The file is then compressed with zip so that we can hack it with plain-text. The article mentioned earlier is very clear and does not say much. Originally prepared to use pkcrack cracked, this tool open source, no restrictions, but the Chinese support is not good. Later I used the hack tool is advanced ZIP Password Recovery 4.0, note that the unregistered version can only recover a file in the compressed package. Here is a simple record to avoid forgetting later.
