Commonly used WinRAR to compress files of various types of friends know, in addition to compressed files, WinRAR can also be used as a cryptographic software, as long as the compressed file to set a password can achieve the purpose of protecting data. But also because of this, specifically for the WinRAR password cracking software is also everywhere. The length of the password for today's crack software, is not the biggest obstacle. So, how can you make winrar encrypted files unbreakable?
We know that the current crack software to crack encrypted file password when the total to specify a encrypted file (object files), and then use the dictionary to crack the password. But if we compress a number of files that need to be encrypted together and then set a different password for each file, it will be helpless to crack the software ... Assuming there is an important file that needs to be encrypted and saved, we can do this:
1. Compress it and set a password according to the usual method;
2. Prepare a different file (of course this file is a little bit better, because we just use it to confuse the software only);
3. In the WinRAR work window to open our first step has been compressed encrypted files, in the Command menu, select the "Add files to the compression package" menu option;
4. In the pop-up "Please select the file to add" dialog box, select the "other files" we prepared, click the "OK" button to return to the "Profile Name and Parameters" dialog box;
5. In the Advanced Tab tab, click the "Set Password" button to set a different password, and then start the compression.
OK, now two passwords have been set up (if you add more than one file, you can also set a different password for each file, if you are worried that you will forget, set only two password can also achieve the goal). We can try to open the compressed file to see is not the upper right corner of each file name has an asterisk to represent the encryption (such as figure), but this asterisk is not equal to the asterisk Oh, open the different files are required to the corresponding password, the use of cracked software is not the correct password. However, if everyone forgets their password, then ... So in the setting of such a password, it is best to have their own easy to remember the law to follow. Not really, we can use Third-party software, such as my password (mypassword) V3.10 to help remember the password.
This method applies to files that are encrypted with WinZip.
