签名和加密几乎成了一些用户的日常工作。虽然加密使未经授权的用户无法读取您的文件，但签名可帮助您声明和验证文件的完整性。有大量适合此任务的工具可用。但是，在签署或加密文件时要遵循的最佳方法和最佳实践是什么？什么是行业公认的最佳标准？在这篇文章中，我们介绍了一个名为Kleopatra的工具，它可以让您使用OpenPGP标准对文件进行加密或签名。
什么是 OpenPGP
OpenPGP是一种协议，最初用于加密电子邮件等通信。该协议/标准定义了加密数据和证书的技术、方法和格式。GnuPG是(GnuPG)OpenPGP标准的开源实现，它允许您对文件进行签名和加密。它基本上是一个命令行工具，有点难以相处。我们今天要讨论的工具，Kleopatra是 GnuPG 的 GUI 实现。

该工具是GnuPG的证书管理器和GUI。它使您只需单击几下即可创建证书、签名和加密文件。鉴于其功能，该工具非常易于使用和理解。它隐藏了签名和加密等操作所涉及的所有复杂性。
在执行任何签名和加密之前，您需要创建自己的证书或密钥对。您可以简单地Ctrl+N来创建一个新的密钥对，或者您可以导入现有的证书文件（如果有的话）。该程序支持几乎所有的证书格式。
如果您正在创建一个新的密钥对，Kleopatra将通过其(Kleopatra)密钥对创建向导(Key Pair Creation Wizard. )使其变得非常简单明了。在第一步中，您可以选择是要创建OpenPGP还是 X.509 密钥。然后，您可以选择在下一步中输入您的姓名和电子邮件。虽然大多数用户可能会从这里开始下一步，但该工具还为您提供了一些高级设置。
您可以决定加密算法并指定在什么情况下使用此证书。最后，您还可以创建一个仅在一段时间内有效的证书。在最后一步中，您可以输入您的密码，请务必记住这一点，因为没有密码您将无法对此证书进行任何操作。
签名和加密
这是关于生成您的密钥对或证书的问题。现在是时候签署或加密您的文件了。通过引入右键单击上下文菜单， Kleopatra(Kleopatra)使执行此操作变得非常简单。因此，您可以右键单击任何文件并选择“签名和加密(Sign and encrypt)”。或者，如果您只想签名并跳过加密，您可以单击更多 GpgEX 选项(More GpgEX Options)并选择相关选项。
您还可以从主应用程序加密或签署文件。您可以使用之前创建或导入的任何证书对文件进行签名。签名完成后，将在同一目录中创建一个.sig文件。(.sig)此文件可用于验证您签署的文件的完整性。如果文件在您签名后被修改，.sig文件将显示无效签名。
Kleopatra是管理文件签名和加密的绝佳工具。它在许多测试用例中很有用，可以帮助您保护文件和信息。它使用了一些底层的最佳标准，而GUI使得处理如此复杂的操作变得非常简单。点击(Click) 这里(here)(here)下载克娄巴特拉。
Sign and Encrypt files using OpenPGP certificates with Kleopatra.
Signing and encryption have almost become a day to day task of some users. While encrурtion makes your file unreadаble to unauthorized users, signing helps you in claiming and verifying the integrity of a file. A plethora of tools are available that are ѕuited to this task. But what is the best ways and best practіceѕ to follow while signing or encrypting your file? Whаt is the best industry accepted standards? In this post, we’ve covered a tоol called Kleopatra that lets you encrypt or sign your files using the OpenPGP standards.
What is OpenPGP
OpenPGP is a protocol which was originally meant for encrypting communications such as emails. This protocol/standard defines techniques, methods, and formats of encrypted data and certificates. GnuPG is an open source implementation of OpenPGP standards, and it allows you to sign and encrypt your files. It is basically a command line tool and a little difficult to get along. The tool that we are going to talk about today, Kleopatra is a GUI implementation of GnuPG.
Sign & Encrypt files using Kleopatra
The tool is a certificate manager and a GUI for GnuPG. It allows you to create certificates, sign and encrypt your files with just a few clicks. Given its capabilities, the tool is quite simple to use and understand. It hides all the complexities involved in operations such as signing and encryption.
Before performing any signing and encryption, you need to create your own certificate or key pair. You can simply hit Ctrl+N to create a new key pair, or you may import existing certificate files if any available. The program supports almost all certificate formats.
If you are creating a new key pair, Kleopatra will make it very simple and straightforward with its Key Pair Creation Wizard. In the first step, you can choose whether you want to create an OpenPGP or an X.509 key. Then you can optionally enter your name and email in the next step. While most of the users might go the next step from here but the tool also provides you with some advanced settings.
You can decide the encryption algorithm and specify in what cases will this certificate be used. Lastly, you can also create a certificate that is only valid until a certain period. In the last step, you can enter your passphrase, make sure you remember this as you will not be allowed to carry out any operations on this certificate without the passphrase.
Signing and Encryption
So that was about generating your key pair or your certificate. Now it is time to sign or encrypt your files. Kleopatra makes it very simple to do that by introducing a right-click context menu. So, you can right-click any file and select ‘Sign and encrypt’. Or if you just want to sign and skip encryption, you can click on More GpgEX Options and select a relevant option.
You can also encrypt or sign your files from the main application. You can sign a file using any of the certificates that you previously created or imported. After signing is complete, a .sig file will be created in the same directory. And this file can be used to validate the integrity of the file you signed. If the file were modified after you’ve signed it, the .sig file would show you an invalid signature.
Kleopatra is a great tool to manage file signing and encryption. It is useful in many test cases and can help you secure your files and information. It uses some of the best standards underneath, and the GUI makes it quite simple to deal with such complex operations. Click here to download Kleopatra.
