如果您不希望任何人都能够打开它，您将需要加密Zip文件。(Zip)在大多数操作系统上，只需双击即可在几秒钟内查看正常的未加密Zip文件，从而显示其中的所有文件。(Zip)
受密码保护的加密 Zip 文件(A password protected, encrypted Zip file)可以防止这种情况，锁定存档，以便只有特定的人才能访问其内容（或任何有Zip 文件解锁器(Zip file unlocker)的人）。
为什么使用 Zip 文件？
想要使用Zip存档而不是仅仅将文件存储在文件夹中，有几个原因，但它们的共同点是易于使用。
Zip文件将数据组织到一个文件夹中，就像一个文件一样，这意味着您可以将数百个文件和文件夹存储在一个位置，而不必担心您可能会意外删除某些内容。这对于文件备份很常见。
您还可以在线共享Zip文件以同时向某人发送多个文件。另一种方法是共享几封电子邮件，一个接一个，附件遍布各处。作为收件人，这通常很难处理，而且绝对不专业。
Zip文件也可以被压缩以节省磁盘空间，如果您打算加密包含大量项目或包含敏感文件的ZIP文件，则应该考虑这一点。(ZIP)

How To Encrypt Zip Files
Yоu’ll want to encrypt a Zip file if you don’t want just anyone to be аble to open it. A normal, unencrypted Zip file can be viewed in seconds on most operating systems with a simple double-click, rеveаling all the files inside.
A password protected, encrypted Zip file prevents this, locking down the archive so that only specific people can access its contents (or anyone who has luck with a Zip file unlocker).
Why Use a Zip File?
There are several reasons to want to use a Zip archive versus just storing the files in a folder, but what they all have in common is ease of use.
Zip files organize data into one single folder that acts just like a file, meaning that you can store hundreds of files and folders in one location without fear that you might accidentally delete some of the content. This is common for file backups.
You can also share Zip files online to send someone multiple files simultaneously. The alternative is to share several emails, one after the other, with attachments strung all over the place. This is usually hard to deal with as a recipient and definitely unprofessional.
A Zip file can be compressed too to save disk space, which is something you should think about if you’re planning on encrypting a ZIP file that has lots of items in it, or one that contains sensitive files.

How To Create & Encrypt a Zip File
You can encrypt files inside a ZIP archive using free tools that you can download in seconds. ZIP encryption works on all operating systems (Windows, Android, macOS, etc).
Windows Zip Encryption
The Zip encryption method we’ll cover for Windows involves using the free 7-Zip program, but there are plenty of other Windows freeware that work similarly, such as PeaZip.
- Select the items you want to add to the encrypted Zip file.
- Right-click one of the files or folders and go to 7-Zip > Add to archive.
- Choose a name for the Zip file and a new location (if you want). By default, the new Zip archive will be created in the same folder that its contents were selected from.
- Make sure zip is chosen in the Archive format drop-down menu.
- Enter the password for the Zip file in the Encryption text boxes on the right.
For added security, feel free to change the encryption method to AES-256.
- Select OK to encrypted the Zip file with a password. It shouldn’t take long, but if you’re encrypting several files and/or folders, or you have a slow computer, you might be waiting several minutes or even hours.
Mac Zip Encryption
To encrypt a Zip file on a Mac, download the free iZip program and then follow these steps:
- Open iZip and press Create Archive.
- Choose Specify name to enter a name for the Zip file and to choose where to save it, and then select Create.
- Enable Extra compression if you want to, and then press Next.
- Check the box next to Enable password protection, and then enter the Zip file password twice.
- Press Next to continue.
- Select an encryption method, preferably the most secure option, AES-256 bit.
- Press Next and then use the plus sign to add the files and folders you want to encrypt in the Zip file.
- SSelect Next and then Next again to start making the encrypted ZIP file. When you see the message Your archive has been created!, you can select Next once more to close that screen and use your new encrypted archive.
