Do you know how to password protect a zip file on Mac? Check out how to secure your information in this brand new post!
Your emails, chats, credit card details, and other personal information stored inside your computer are very critical and prone to data theft. We cannot simply depend on anti-virus for these details especially when you are not using comprehensive malware protection software.
To achieve data security, encrypting these types of files can help you protect yourself and other important documents. Apple has built-in features that can help you encrypt files and folders conveniently. There are two basic methods to encrypt files on a Mac and we will discuss both options.
Apple has excellent credibility when it comes to security; however, we cannot just be confident in knowing that compressed files are safe enough. To better ensure protection, you can securely password
The easiest method to encrypt a folder is by using the free tool on Mac which is the Disk Utility. Follow these steps on how to use this feature;
That’s it! You have successfully encrypted your folders via disk utility. You can now delete the old folder and use this newly password protected one.
Print to PDF
The next method available to encrypt files and folders on a Mac is the print to PDF option. We may not have noticed it before but yes, there is an option where you can set a password on a file upon using the print to PDF setting.
This option works on any files types as long as it gives you the “print to PDF” choice.
Basically, you can see the “Print to PDF” under the Print window. Here’s how:
To access the encrypted files, simply open the desired file and enter the password when asked. Upon entering the password, make sure that the box is unchecked for “Remember my password in my keychain”.
Encryption alone is weak when it comes to protecting your personal information that is why it is highly recommended that you use AES-256 encryption. For Mac users, there are third-party apps that provide seamless protection for your personal data. One of those working apps is Keka which is the macOS file archiver that allows you to store more and share files with privacy.
This software easily lets you perform file compression and decompression for Mac; however, it is not using AES for encrypting Zip files by default.
Another safe and free method to secure zip files is by using the Terminal or the command line.
You will now see the file named “archivename.zip”. It is now encrypted with the password provided. Be sure to remember your password because you need this every time you need to open the archived file.
For compressing multiple files inside a folder, you can simply modify the command with the -er flag so it will be: zip -er archive.zip /path/to/directory/
This command is important for encrypting zip of multiple files under OS X Mavericks.
To decompress the files, you can enter these commands in the terminal: unzip filename.zip.
However, you don’t need to use Terminal upon accessing or opening a password protected zip file. If you are not highly skilled in using terminal then you can easily open the compressed from the Mac OS X Finder or within Windows using standard unzipping apps.
Simply double click on the compressed file and then enter the password you have set, and files will decompress.
In any of these given cases below, you can compress and archive the files for security purposes. However, this method does not have deeper security.
Even when we delete files inside our devices, these files still leave traces and footprints in the system. This may mean that the files are not fully removed but rather been transferred to another folder waiting for data overwriting. So if you are planning to sell your Mac, be sure to completely remove all the vital information you stored inside. How do you make sure you got everything cleared?
Use a file shredder and cleaner software such as iMyMac. It easily and conveniently locates important files and shreds them and replaces the footprints with unreadable codes so no software can retrieve its contents.
Finally, you have learned how to password protect a zip file in a Mac. Hopefully, you can practice these methods to secure and ensure that no data is taken from you.
