Just right-click the file you want to encrypt and from the pop-up menu, select “ compress“. Encrypting a file with 7 zipħ zip is very easy to use. Let’s look into how we can actually encrypt a file. If you happen to be on Linux, then there is a good chance that 7 zip is already installed. If you run Windows then ether type “7 zip” into your search engine of choice or on this page: Passwords are a huge topic and I will dedicate the next part to just that. The only requirement is knowing the password. One of the biggest advantages of 7 zip is that once you encrypt a file, you can open it on any computer. The easiest way to encrypt a file is simply to use 7 zip. The second one is GPG and is best used on a trusted computer that runs Linux. The first one is 7 zip which is a free program that works on Windows, Linux and OS X. I will explain two methods which I use a lot. So the strongest format is 7Z, followed by ZIP-AES-256.Ĭonclusion: in the case of encrypted files, there is no sane reason to still use standard zip.The second of the three part series explains how to encrypt your data. zip also has more code execution vulnerabilities compared to 7Z. Basically, there is some software that can search passwords for zip, and it's more difficult to find such software for 7z-AES. It also slightly simpler to check passwords for zip, since many tools are focused on that compared to 7z. If 128-bit is used, it's less secure, but a little faster. When using AES WinZIP can use both 128-bit and 256-bit. zip purpose, since Windows by itself will not be able to extract it. Using WinZIP with AES defeats the initial. Do not rely on Zip 2.0 encryption to provide strong data security. But that method provides low security level. WinZip offers two kinds of encryption: AES encryption (It's good, but windows doesn't support it.) and weak Zip 2.0 (Legacy) encryption, which is the old method. 7-zip uses AES-256 for 7z archives, the strongest version of AES.
