Probably many familiar with the situation when you can not remember the password to any encrypted file or fails to enter into a social network because of the fact that the password is lost. Often, the information is protected by forgotten passwords, it is very important, so we have to look for ways to recover lost data and somehow open the encrypted file or find a forgotten password to it. In this article, we will focus on the remove password to zip can be done using a special program, for example, such as Manyprog Zip Password Recovery.
Modern archivers using strong encryption algorithm, for example, AES with 128- and 256-bit keys. WinZip 8.0 and earlier versions of it have very little protection, so files that are encrypted in such archivers, guaranteed to be hacked within an hour of almost any program designed for this purpose. To recover passwords to archives created by WinZip later, using different technologies that carry the selection keys in some way. What methods are used by programs to search for a password to zip archive, in order to find the password for the zip?
If you have any further information about the key, such as the length or the presence in the password of any character, you can use brute force on a given mask. The rate of selection of the password will be significantly increased. Another well-known method of password recovery is a dictionary attack. The dictionary contains a set of passwords, which are often used by users to protect their data. Statistics show that the majority of passwords to protect files contains the words from the dictionary. There exists a large number of dictionaries. If desired, the user programs to find the password itself can create a dictionary of passwords and specify the intended program path. In general, the dictionary includes words and their various combinations in multiple languages and in different registers. It is worth to mention the brute force of all possible combinations of characters in a password. Of course, it is a long and not very efficient way, but sometimes it is the only possible method for finding the password.
