Encrypting a ZIP file also protects it during transmission. Besides, someone can still access the files if they use the hard drive on a different computer.įile encryption ensures that even if someone finds out the password to your computer, they still cannot view the contents of your ZIP file. If you are archiving essential documents or pictures, chances are they contain some content you don't want to expose to the world.Īnd yes, you can put a strong password on your user account and use Windows security features, but such a move is not adequate since you may leave the computer on by mistake. An encrypted ZIP file has an added layer of protection for confidential information. What is an encrypted ZIP file?Įncryption involves protecting a ZIP file by locking down the archive such that only specific people can view its contents.

Additionally, they save your disk space since it allows compressing of large attachments. With ZIP files, you can store hundreds of folders and files in a single location, thus making it convenient to transfer and use. Of course, they would not be able to open any of the files without the password.The idea of compressing content into ZIP files has revolutionized the digital workspace. If the file names provide sensitive information, a thief could take advantage of that. One more problem with encrypted ZIP files: No matter which form of encryption you use, anyone with access to the files can see the name of the files within the archive. You’ll find these options near the lower-right corner of the dialog box. To encrypt an archive in 7-zip, once you’re at the Add to Archive dialog box, enter a password and select the Encryption method AES-256. Email someone an AES-encrypted file, text them the password (safer than emailing it), and if they try to open it in Windows Explorer or File Explorer, they won’t be able to open any of the files within the archive.įortunately, most third-party zip tools, including the free 7-zip, support AES-256.

Assuming you use a strong password, it’s for all practical purposes unbreakable.īut when you use it for ZIP archives, AES-256 comes with another problem: Windows’ own, built-in compression tool doesn’t support AES. It’s a popular and extremely strong encryption technique used in many programs. Unlike ZipCrypto, AES was not designed for ZIP files. You’d be far safer using the other option, AES-256.
