- 方法一：
* 1.使用ZIP命令创建一个加密的ZIP文件：
* 2.解压缩加密文件时，会提示要求输入密码：
- 方法二:
* 1.使用7z创建一个zip文件：
* 2.解压缩加密文件:
- 方法三：
* 1.To create an encrypted compressed tar archive with GnuPG:
* 2.To uncompress an archive file encrypted with GnuPG:
假设你想创建一个zip归档文件，并且具有密码保护，这样不管是谁试图解压这个zip文件时候，都必须知道正确的密码。在Linux上，有几种方法可以加密ZIP文件，或者对zip文件进行密码保护.
下面我们来介绍常用的3种加密方式：
方法一：
zip命令行工具提供了一个加密选项。
zip命令所使用的是PKZIP加密算法。
PKZIP算法被称为是不安全的。
此外，设置的密码，被以纯文本显示，使得它更加脆弱。
1.使用ZIP命令创建一个加密的ZIP文件：
$ zip --password mypasscode all.zip 1.txt 2.txt
adding: 1.txt (stored 0%)
adding: 2.txt (stored 0%)
2.解压缩加密文件时，会提示要求输入密码：
$unzip all.zip
Archive: all.zip
[all.zip] 1.txt password:
方法二:
使用7z进行文件归档，可以创建更加安全的加密zip文件，7z使用AES-256加密算法，SHA-256散列算法生成密钥。
1.使用7z创建一个zip文件：
$ 7z a -t7z -p doc_folder.7z doc_folder
7-Zip [64] 9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18
p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,4 CPUs)
Scanning
Creating archive doc_folder.7z
Enter password (will not be echoed) :
Verify password (will not be echoed) :
Compressing doc_folder/.7z
Compressing doc_folder/test.txt
Everything is Ok
2.解压缩加密文件:
$ 7z x doc_folder.7z
7-Zip [64] 9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18
p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,4 CPUs)
Processing archive: doc_folder.7z
Enter password (will not be echoed) :
Extracting doc_folder/.7z
Extracting doc_folder/test.txt
Extracting doc_folder
Everything is Ok
Folders: 1
Files: 2
Size: 37
Compressed: 252
方法三：
还有一种创建加密压缩包的方式，就是采用GnuPG的对称密钥加密
1.To create an encrypted compressed tar archive with GnuPG:
$ tar czvpf – doc.pdf doc2.pdf doc3.pdf | gpg --symmetric --cipher-algo aes256 -o secure.tar.gz.gpg
2.To uncompress an archive file encrypted with GnuPG:
$ gpg -d secure.tar.gz.gpg | tar xzvf -
