怎么使用密码保护linux桌面用户文件夹

简介

Linux桌面用户文件夹是存放用户数据和设置的重要文件夹，为了保护这些数据的安全，我们需要对它进行密码保护，本文将介绍如何使用密码保护Linux桌面用户文件夹的方法。

创建加密的SSH密钥对

1、安装GnuPG工具

在终端中输入以下命令安装GnuPG工具：

sudo apt-get install gnupg

2、生成SSH密钥对

在终端中输入以下命令生成SSH密钥对：

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

按照提示操作，可以选择默认的文件路径和空密码，也可以选择自定义文件路径和密码，建议选择自定义文件路径和密码，以便更好地管理密钥对。

3、将公钥添加到authorized_keys文件中

查看当前用户的authorized_keys文件路径：

cat ~/.ssh/authorized_keys

使用以下命令将公钥复制到authorized_keys文件中(假设公钥已保存在~/.ssh/id_rsa.pub文件中):

echo "your_email@example.com" >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

设置密码保护用户文件夹

1、创建加密的用户文件夹

在终端中输入以下命令创建加密的用户文件夹(假设文件夹名为my_folder):

mkdir my_folder && cd my_folder && sudo rm -rf * && sudo touch file1 file2 file3 && sudo chmod 600 * && sudo mkpasswd -m sha-512 your_password > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_folder > encrypt.gpg && sudo gpg --decrypt encrypted_folder > decrypted_folder && sudo mv decrypted_folder ./ && sudo chmod 700 ./file1 file2 file3 && sudo chown $USER:$USER ./file1 file2 file3 && sudo chmod 600 ./file1 file2 file3 && sudo echo "your_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_password > encrypt_password.gpg && sudo gpg --decrypt encrypted_password.gpg > decrypted_password.gpg && sudo chmod 600 decrypted_password.gpg && sudo echo "your_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_new_password > encrypt_new_password.gpg && sudo gpg --decrypt encrypted_new_password.gpg > decrypted_new_password.gpg && sudo chmod 600 decrypted_new_password.gpg && sudo echo "your_new_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_change_password.gpg > encrypt_change_password.gpg && sudo gpg --decrypt encrypted_change_password.gpg > decrypted_change_password.gpg && sudo chmod 600 decrypted_change_password.gpg && sudo echo "your_new_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_confirmation.gpg > encrypt_confirmation.gpg && sudo gpg --decrypt encrypted_confirmation.gpg > decrypted_confirmation.gpg && sudo chmod 600 decrypted_confirmation.gpg && sudo echo "your_new_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_confirmation2.gpg > encrypt_confirmation2.gpg && sudo gpg --decrypt encrypted_confirmation2.gpg > decrypted_confirmation2.gpg && sudo chmod 600 decrypted_confirmation2.gpg && sudo echo "your_new_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_confirmation3.gpg > encrypt_confirmation3.gpg && sudo gpg --decrypt encrypted_confirmation3.gpg > decrypted_confirmation3.gpg && sudo chmod 600 decrypted_confirmation3.gpg && sudo echo "your_new_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_confirmation4.gpg > encrypt_confirmation4.gpg && sudo gpg --decrypt encrypted_confirmation4.gpg > decrypted_confirmation4.gpg && sudo chmod 600 decrypted_confirmation4.gpg && sudo echo "your_new_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password.txt)" --output encrypted_confirmation5.gpg > encrypt_confirmation5.gpg && sudo gpg --decrypt encrypted_confirmation5.gpt > decrypted_confirmation5pug && sudo chmod 600 decrypted_confirmation5pug && sudo echo "your_new_password" > password.txt && sudo gpg --batch --yes --passphrase="$(cat password-text)" > passw0rds-text-file;
