Windows 记事本(Windows Notepad)是每个版本的Windows中都包含的多功能文本编辑器。您可以将其用于记笔记和列表制作等基本任务，或创建批处理文件以在计算机上自动执行命令等更高级的任务。
有时，您可能会在记事本(Notepad)中写一些需要额外安全性的重要内容。加密记事(Notepad)本文本文件是提高安全性的最佳选择。因此，这是您在Windows 10中加密和解密文本文件的方法。
1.Windows加密文件系统(1. Windows Encrypting File System)
Windows 加密文件系统(Windows Encrypting File System)( EFS ) 是一个集成的文件加密工具，适用于除家庭版以外的所有(Home)Windows 10版本。EFS与可用于全盘加密的Bitlocker不同。相反，EFS在逐个文件的基础上工作，这使得它非常适合加密文本文件。
要使用EFS加密文件，请右键单击文本文件并选择Properties。现在，选择“高级”，然后选中“(Advanced, )加密内容以保护数据(Encrypt contents to secure data)”复选框。按OK，然后按应用。(Apply.)
将出现加密警告(Encryption Warning)，说明在某些情况下加密单个文件可能会导致问题，并且加密整个文件夹可提供更多保护。如果该文件位于经常访问的文件夹中，这意味着您每次要访问任何其他文件时都必须解锁该文件夹。解决此问题的一种方法是将文本文件放在单独的文件夹中，并将其用作安全文件夹。
确认您的选择后，加密文件系统(Encrypting File System)将询问您是否要备份加密密钥。如果您忘记了解密密码，您可以使用加密密钥备份。
导出您的加密密钥备份(Exporting Your Encryption Key Backup)
如果您选择导出加密密钥备份以提高安全性，Microsoft 证书导出向导(Microsoft Certificate Export Wizard)将运行。该向导将指导您创建加密密钥并将其导出到外部媒体源，例如USB闪存驱动器。
从第一页中选择个人信息交换，然后选中(Personal Information Exchange)导出所有扩展属性(Export all extended properties)。在下一页上，您必须输入一个安全且唯一的密码(input a secure and unique password)来保护您的文本文件。将加密类型切换为AES256-SHA256（extremely strong encryption!），然后给您的加密密钥备份一个文件名。按完成(Finish)以完成该过程。
该过程完成后，您会在文本文件图标上看到一个小锁图标，指示其加密状态。
2. 7-Zip
您(Did)知道存档工具7-Zip还具有加密工具( also features an encryption tool)吗？对于无法使用Windows 加密文件系统(Windows Encrypting File System)但仍希望快速加密文本文件的Windows 10 家庭(Home)用户， 7-Zip 选项非常方便。
7 -Zip(7-Zip)加密过程不同于EFS选项。首先(First)，您必须下载并安装最新版本的7-Zip。安装后，右键单击要加密的文本文件。(Once)选择7-Zip > Add to Archive以打开 7-Zip 存档选项。
找到右侧的加密部分。(Encryption)输入一个强大且唯一的密码，然后按OK。
现在，当您要访问该文件时，您必须输入密码才能解密文本文件（或存档中的任何其他文件）。7-Zip 的加密工具是一种轻松加密多个文本文件的便捷方式。
3. AES 加密(3. AES Crypt)
AES Crypt是一个免费的开源工具，可用于加密文本文件。AES Crypt的最大优点之一就是易于使用。
您照常安装AES Crypt。安装后，右键单击要加密的文本文件，然后从上下文菜单中选择AES Crypt 。输入一个强大且唯一的密码，然后按OK。AES Crypt创建文本文件的加密副本。
唯一要记住的是删除原始文件。这有两个原因。首先(First)，如果有人可以访问未加密的原件，则加密的副本将毫无用处。其次，如果AES Crypt(AES Crypt)检测到它仍然存在，您将无法解密您的文本文件。
供您考虑的最后一个单文件加密工具是AxCrypt，这是一款功能强大的加密工具，具有广泛的功能。但是，您无需担心所有功能——只需担心AxCrypt将如何加密和解密您的文本文件。
下载并安装AxCrypt。第一次启动AxCrypt时，您必须运行设置。您必须提供有效的电子邮件地址才能接收验证码（本质上是您的免费AxCrypt许可证），然后在确认之前复制并粘贴代码。
接下来，您需要创建您的AxCrypt加密密码。这将加密和解密您的个人文本文件，因此请确保创建一个强大且唯一的密码。如警告所述，密码重置将使您重新进入您的帐户，但它不会解密使用旧密码保护的文本文件。
准备好后，将文本文件拖放到AxCrypt中。AxCrypt将自动加密文件。如果您登录到AxCrypt，您将不会收到用于解密文本文件的密码提示。关闭AxCrypt 后(AxCrypt)，您将收到密码提示。
AxCrypt是一个免费的加密工具，这就是为什么它出现在我们的最佳 Windows 免费软件程序列表中(list of the best Windows freeware programs)。

How To Encrypt & Decrypt a Text File In Windows 10
The Windows Notеpad is a vеrsatile text editor included іn every version оf Windows. You can use it for basic tasks such as note-taking and list-making, or mоre advanced tаsks such as creatіng a batch file to aυtomate commands on your comрuter.
At times, you might write something important in Notepad that requires extra security. Encrypting your Notepad text file is the best option to increase your security. So, here’s how you encrypt and decrypt a text file in Windows 10.
1. Windows Encrypting File System
The Windows Encrypting File System (EFS) is an integrated file encryption tool available to all Windows 10 versions except Home. EFS is not the same as Bitlocker, which you can use for full disk encryption. Instead, EFS works on a file-by-file basis, which makes it perfect for encrypting a text file.
To use EFS to encrypt your file, right-click the text file and select Properties. Now, select Advanced, then check the box to Encrypt contents to secure data. Press OK, then Apply.
The Encryption Warning will appear, explaining that encrypting the single file can cause an issue under certain circumstances and that encrypting the entire folder offers more protection. If the file is in a frequently accessed folder, this means you’ll have to unlock the folder each time you want to access any other file. One way around this is to place your text file in a separate folder and use this as your secure folder.
After confirming your selection, the Encrypting File System will ask you if you want to take a backup of the encryption key. You can use the encryption key backup if you forget your decryption password.
Exporting Your Encryption Key Backup
If you choose to export your encryption key backup for additional security, the Microsoft Certificate Export Wizard will run. The wizard will guide you through the creation and export of your encryption key to an external media source, such as a USB flash drive.
Select Personal Information Exchange from the first page, and check Export all extended properties. On the next page, you must input a secure and unique password to protect your text files. Switch the encryption type to AES256-SHA256 (extremely strong encryption!), then give your encryption key backup a filename. Press Finish to complete the process.
Once the process is complete, you’ll see a small lock icon on the text file icon, indicating its encryption status.
2. 7-Zip
Did you know that the archive tool, 7-Zip, also features an encryption tool? The 7-Zip option is handy for Windows 10 Home users who cannot use the Windows Encrypting File System and still want a quick way to encrypt text files.
The 7-Zip encryption process is different from the EFS option. First, you must download and install the latest version of 7-Zip. Once installed, right-click the text file you want to encrypt. Select 7-Zip > Add to Archive to open the 7-Zip archive options.
Find the Encryption section on the right. Enter a strong and unique password, then press OK.
Now, when you want to access the file, you must input your password to decrypt the text file (or any other file in the archive). 7-Zip’s encryption tool is a handy way to encrypt several text files with minimal fuss.
3. AES Crypt
AES Crypt is a free and open-source tool you can use to encrypt text files. One of the best things about AES Crypt is the ease of use.
You install AES Crypt as normal. Once installed, right-click the text file you want to encrypt and select AES Crypt from the context menu. Enter a strong and unique password, then press OK. AES Crypt creates an encrypted copy of the text file.
The only thing to remember is to delete the original file. This is for two reasons. First, the encrypted copy is useless if someone can access the unencrypted original. Second, you won’t be able to decrypt your text file if AES Crypt detects that it still exists.
The final single-file encryption tool for you to consider is AxCrypt, a powerful encryption tool with extensive features. However, you don’t need to worry about all of the features—just how AxCrypt will encrypt and decrypt your text file.
Download and install AxCrypt. The first time you launch AxCrypt, you have to run through the setup. You must provide an active email address to receive a verification code (which is essentially your free AxCrypt license), then copy and paste the code before confirming.
Next, you need to create your AxCrypt encryption password. This will encrypt and decrypt your personal text files, so make sure to create a strong and unique password. As the warning states, a password reset will let you back into your account, but it will not decrypt text files secured with the old password.
When you’re ready, drag and drop your text file into AxCrypt. AxCrypt will encrypt the file automatically. If you are logged into AxCrypt, you will not receive a password prompt to decrypt the text file. Once you close AxCrypt, you will receive a password prompt.
AxCrypt is a free encryption tool, which is why it features in our list of the best Windows freeware programs.
What’s The Best Way To Encrypt Text Files?
You have four options for encrypting your text files. The easiest option is 7-Zip, which is free, easy to use, and provides strong protection. That said, none of the other options are difficult to use—so long as you don’t forget your password!
Password creation can seem daunting. If you’re struggling, check out these easy ways to create a password you’ll always remember.
