Even as more and more of our data is housed on websites and cloud services, protected by user accounts with ever-more secure and challenging passwords, there's still great value in being able to store sensitive data on our own filesystems, especially when we can encrypt that data quickly and easily. - -[Age][2] allows you to do this. It is a small, easy-to-use tool that allows you to encrypt a file with a single passphrase and decrypt it as required. - -### Install age - -Age is available to [install][3] from most Linux repositories. - -To install it on Fedora: - - -``` -`$ sudo dnf install age -y` -``` - -On macOS, use [MacPorts][4] or [Homebrew][5]. On Windows, use [Chocolatey][6]. - -### Encrypting and decrypting files with age - -Age can encrypt and decrypt files with either a public key or a passphrase set by the user. - -#### Using age with a public key - -First, generate a public key and write the output to a `key.txt` file: - - -``` -$ age-keygen -o key.txt -Public key: age16frc22wz6z206hslrjzuv2tnsuw32rk80pnrku07fh7hrmxhudawase896m9 -``` - -### Encrypt with a public key - -To encrypt a file with your public key: - - -``` -`$ touch mypasswds.txt | age -r ageage16frc22wz6z206hslrjzuv2tnsuw32rk80pnrku07fh7hrmxhudawase896m9 > mypass.tar.gz.age` -``` - -In this example, the file `mypasswds.txt` is encrypted with the public key I generated and put inside an encrypted file called `mypass.tar.gz.age`. - -### Decrypt with a public key - -To decrypt the information you've protected, use the `age` command and the `--decrypt` option: - - -``` -`$ age --decrypt -i key.txt -o mypass.tar.gz mypass.tar.gz.age` -``` - -In this example, age uses the key stored in `key.text` and decrypts the file I created in the previous step. - -### Encrypt with a passphrase - -Encrypting a file without a public key is known as symmetrical encryption. It allows a user to set the passphrase to encrypt and decrypt a file. To do so: - - -``` -$ age --passphrase --output mypasswd-encrypted.txt mypasswd.txt -Enter passphrase (leave empty to autogenerate a secure one):   -Confirm passphrase: -``` - -In this example, age prompts you for a passphrase, which it uses to encrypt the input file `mypasswd.txt` and render the file `mypasswd-encrypted.txt` in return. - -### Decrypt with a passphrase - -To decrypt a file encrypted with a passphrase, use the `age` command with the `--decrypt` option: - - -``` -`$ age --decrypt --output passwd-decrypt.txt mypasswd-encrypted.txt` -``` - -In this example, age prompts you for the passphrase, then decrypts the contents of the `mypasswd-encrypted.txt` file into `passwd-decrypt.txt`, as long as you provide the passphrase that matches the one set during encryption. - -### Don't lose your keys - -Whether you're using passphrase encryption or public-key encryption, you _must not_ lose the credentials for your encrypted data. By design, a file encrypted with age cannot be decrypted without the key used to encrypt it. So back up your public key, and remember those passphrases! - -### Easy encryption at last - -Age is a really robust tool. I like to encrypt my sensitive files, especially tax records and other archival data, into a `.tz` file for later access. Age is user-friendly and makes it very easy to get started with encryption on the go. - --------------------------------------------------------------------------------- - -via: https://opensource.com/article/21/7/linux-age - -作者：[Sumantro Mukherjee][a] -选题：[lujun9972][b] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]: https://opensource.com/users/sumantro -[b]: https://github.com/lujun9972 -[1]: https://opensource.com/sites/default/files/styles/image-full-size/public/lead-images/document_free_access_cut_security.png?itok=ocvCv8G2 (Scissors cutting open access to files) -[2]: https://github.com/FiloSottile/age -[3]: https://github.com/FiloSottile/age#installation -[4]: https://opensource.com/article/20/11/macports -[5]: https://opensource.com/article/20/6/homebrew-mac -[6]: https://opensource.com/article/20/3/chocolatey diff --git a/translated/tech/20210708 Encrypt and decrypt files with a passphrase on Linux.md b/translated/tech/20210708 Encrypt and decrypt files with a passphrase on Linux.md new file mode 100644 index 0000000000..21deea9522 --- /dev/null +++ b/translated/tech/20210708 Encrypt and decrypt files with a passphrase on Linux.md @@ -0,0 +1,118 @@ +[#]: subject: (Encrypt and decrypt files with a passphrase on Linux) +[#]: via: (https://opensource.com/article/21/7/linux-age) +[#]: author: (Sumantro Mukherjee https://opensource.com/users/sumantro) +[#]: collector: (lujun9972) +[#]: translator: (geekpi) +[#]: reviewer: ( ) +[#]: publisher: ( ) +[#]: url: ( ) + +在 Linux 上用密码加密和解密文件 +====== +age 是一个简单的、易于使用的工具，允许你用一个密码来加密和解密文件。 +![Scissors cutting open access to files][1] + +长期以来，保护文件和敏感文档的加密和安全一直是用户关心的问题。即使我们越来越多的数据被存放在网站和云服务上，并由带有越来越安全和具有挑战性的密码的用户账户来保护，但能够在我们自己的文件系统中存储敏感数据仍有很大的价值，特别是当我们能够快速和容易地加密这些数据时。 + +[age][2] 能让你这样做。它是一个小型的、易于使用的工具，允许你用一个密码加密一个文件，并根据需要解密。 + +### 安装 age + +age 可以在大多数 Linux 软件库中[安装][3]。 + +要在 Fedora 上安装它： + + +``` +`$ sudo dnf install age -y` +``` + +在 macOS 上，使用 [MacPorts][4] 或 [Homebrew][5]。在 Windows 上，使用 [Chocolatey][6]。 + +### 用 age 加密和解密文件 + +age 可以用公钥或用户设置的密码来加密和解密文件。 + +#### 在 age 中使用公钥 + +首先，生成一个公钥并写入 `key.txt` 文件： + + +``` +$ age-keygen -o key.txt +Public key: age16frc22wz6z206hslrjzuv2tnsuw32rk80pnrku07fh7hrmxhudawase896m9 +``` + +### 使用公钥加密 + +要用你的公钥加密一个文件： + + +``` +`$ touch mypasswds.txt | age -r ageage16frc22wz6z206hslrjzuv2tnsuw32rk80pnrku07fh7hrmxhudawase896m9 > mypass.tar.gz.age` +``` + +在这个例子中，文件 `mypasswds.txt` 被我生成的公钥加密，放在一个叫做 `mypass.tar.gz.age` 的加密文件中。 + +### 用公钥解密 + +要解密你所保护的信息，使用 `age` 命令和 `--decrypt` 选项： + + +``` +`$ age --decrypt -i key.txt -o mypass.tar.gz mypass.tar.gz.age` +``` + +在这个例子中，age 使用存储在 `key.text` 中的密钥，并解密了我在上一步创建的文件。 + +### 使用密码加密 + +在没有公开密钥的情况下对文件进行加密被称为对称加密。它允许用户设置密码来加密和解密一个文件。要做到这一点： + + +``` +$ age --passphrase --output mypasswd-encrypted.txt mypasswd.txt +Enter passphrase (leave empty to autogenerate a secure one): +Confirm passphrase: +``` + +在这个例子中，age 提示你输入一个密码，它用这个密码对输入文件 `mypasswd.txt` 进行加密，并生成文件 `mypasswd-encrypted.txt`。 + +### 使用密码解密 + +要解密一个用密码加密的文件，可以使用 `age` 命令和 `--decrypt` 选项： + + +``` +`$ age --decrypt --output passwd-decrypt.txt mypasswd-encrypted.txt` +``` + +在这个例子中，age 提示你输入密码，然后将 `mypasswd-encrypted.txt` 文件的内容解密为 `passwd-decrypt.txt`，只要你提供的密码与加密时设置的密码一致。 + +### 不要丢失你的密钥 + +无论你是使用密码加密还是公钥加密，你都_不能_丢失加密数据的凭证。根据设计，如果没有用于加密的密钥，用 age 加密的文件是不能被解密的。所以，请备份你的公钥，并记住这些密码！ + +### 轻松实现加密 + +age 是一个真正强大的工具。我喜欢把我的敏感文件，特别是税务记录和其他档案数据，加密到 `.tz` 文件中，以便以后访问。age 是用户友好的，使其非常容易随时加密。 + +-------------------------------------------------------------------------------- + +via: https://opensource.com/article/21/7/linux-age + +作者：[Sumantro Mukherjee][a] +选题：[lujun9972][b] +译者：[geekpi](https://github.com/geekpi) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://opensource.com/users/sumantro +[b]: https://github.com/lujun9972 +[1]: https://opensource.com/sites/default/files/styles/image-full-size/public/lead-images/document_free_access_cut_security.png?itok=ocvCv8G2 (Scissors cutting open access to files) +[2]: https://github.com/FiloSottile/age +[3]: https://github.com/FiloSottile/age#installation +[4]: https://opensource.com/article/20/11/macports +[5]: https://opensource.com/article/20/6/homebrew-mac +[6]: https://opensource.com/article/20/3/chocolatey
