How To Crack Into A Zip File __TOP__
ZIP is an archive file format that supports lossless data compression. By lossless compression, we mean that the compression algorithm allows the original data to be perfectly reconstructed from the compressed data. So, a ZIP file is a single file containing one or more compressed files, offering an ideal way to make large files smaller and keep related files together. Some ZIP files are password protected to secure the files from outsiders by disabling their access to the files. But, there are multiple methods to crack a password protected zip file to access its content.

Getting stuck in a situation where you lost your password can be very annoying when you need to access the file urgently. We have provided you with four effective methods on how to crack ZIP file password. Choose the best method according to your needs and easily crack your ZIP file password.
Zipped (compressed) files take up less storage space and can be transferred to other computers more quickly than uncompressed files. In Windows, you work with zipped files and folders in the same way that you work with uncompressed files and folders. Combine several files into a single zipped folder to more easily share a group of files.
Press and hold (or right-click) the file or folder, select (or point to) Send to, and then select Compressed (zipped) folder.A new zipped folder with the same name is created in the same location. To rename it, press and hold (or right-click) the folder, select Rename, and then type the new name.
If you add encrypted files to a zipped folder, they'll be unencrypted when they're unzipped, which might result in unintentional disclosure of personal or sensitive information. For that reason, we recommend that you avoid zipping encrypted files.
Some types of files, like JPEG images, are already highly compressed. If you zip several JPEG pictures into a folder, the total size of the folder will be about the same as the original collection of pictures.
This wikiHow teaches you how to gain access to a ZIP folder which has an unknown password. The only way to do this is by downloading a program which can crack the password for you, though the process of cracking the password can take days to complete.
For example, the Linux command line zip utility uses the older PKZIP algorithm, which is insecure and easy to crack. Other programs, like WinZip and 7-Zip, use strong AES-256 encryption. Earlier versions of the RAR protocol use a proprietary encryption algorithm, while newer versions use AES. WinRAR and PeaZip, popular choices that can deal with RAR files, also use the AES standard.
Linux shadow files themselves are not encrypted, but the passwords contained within them are. Encryption algorithms used for these can vary depending on the system, but MD5, SHA-512, SHA-256, Blowfish, and DES are all commonly used.
This gives us a nice little banner, a usage example, and some information about some of the options available. It also gives us an error stating it needs a file, and tells us to use --help for more info; this will give us more details and options:
Before we can run Zydra, we will need some files to test it out on. I have created a RAR file, ZIP file, and PDF file that you can download and use to follow along. The password for all three of these is "password1" as you'll soon find out. There is also a shadow file you can download, which I got from the Metasploitable virtual machine.
Zydra can operate in two modes: dictionary and brute force. In dictionary mode, we just need to supply a wordlist with the -d flag. We also need to specify the file we are trying to crack using the -f flag:
For brute force mode, we need to set a few more options. We still specify the file to crack, but now we can use the -b flag to set the character types to use for brute forcing. The minimum and maximum length of the password can also be set now, using the -m and -x flags, respectively:
Again, we can see it found the password, but this time there is an additional dialogue. This is simply telling us the file is a decrypted version of the original, which we can verify with the file command: 350c69d7ab
