Managing credentials with KeePassXC
|
|
||||||
======
|
|
||||||
|
|
||||||
![][1]
|
|
||||||
|
|
||||||
A [previous article][2] discussed password management tools that use server-side technology. These tools are very interesting and suitable for a cloud installation.
|
|
||||||
In this article we will talk about KeePassXC, a simple multi-platform open source software that uses a local file as a database.
|
|
||||||
The main advantage of this type of password management is simplicity. No server-side technology expertise is required and can therefore be used by any type of user.
|
|
||||||
|
|
||||||
### Introducing KeePassXC
|
|
||||||
|
|
||||||
KeePassXC is an open source cross platform password manager: its development started as a fork of KeePassX, a good product but with a not very active development. It saves the secrets in an encrypted database with AES algorithm using 256 bit key, this makes it reasonably safe to save the database in a cloud drive storage such as pCloud or Dropbox.
|
|
||||||
|
|
||||||
In addition to the passwords, KeePassXC allows you to save various information and attachments in the encrypted wallet. It also has a valid password generator that helps the user to correctly manage his credentials.
|
|
||||||
|
|
||||||
### Installation
|
|
||||||
|
|
||||||
The program is available both in the standard Fedora repository and in the Flathub repository. Unfortunately the integration with the browser does not work with the application running in the sandbox, so I suggest to install the program via dnf:
|
|
||||||
```
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
sudo dnf install keepassxc
|
|
||||||
```
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
### Creating your wallet
|
|
||||||
|
|
||||||
To create a new database there are two important steps:
|
|
||||||
|
|
||||||
* Choose the encryption settings: the default settings are reasonably safe, increasing the transform rounds also increases the decryption time.
|
|
||||||
* Choose the master key and additional protections: the master key must be easy to remember (if you lose it your wallet is lost!) but strong enough, a passphrase with at least 4 random words can be a good choice. As additional protection you can choose a key file (remember: you must always have it available otherwise you cannot open the wallet) and / or a YubiKey hardware key.
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
![][3]
|
|
||||||
|
|
||||||
![][4]
|
|
||||||
|
|
||||||
The database file will be saved to the file system. If you want to share with other computers / devices you can save it on a USB key or in a cloud storage like pCloud or Dropbox. Of course, if you choose a cloud storage, a particularly strong master password is recommended, better if accompanied by additional protection.
|
|
||||||
|
|
||||||
### Creating your first entry
|
|
||||||
|
|
||||||
Once the database has been created, you can start creating your first entry. For a web login specify a username, password and url in the Entry tab. Optionally you can specify an expiration date for the credentials based on your personal policy: also by pressing the button on the right the favicon of the site is downloaded and associated as an icon of the entry, this is a nice feature.
|
|
||||||
|
|
||||||
![][5]
|
|
||||||
|
|
||||||
![][6]
|
|
||||||
|
|
||||||
KeePassXC also offers a good password / passphrase generator, you can choose length and complexity and check the degree of resistance to a brute force attack:
|
|
||||||
|
|
||||||
![][7]
|
|
||||||
|
|
||||||
### Browser integration
|
|
||||||
|
|
||||||
KeePassXC has an extension available for all major browsers. The extension allows you to fill in the login information for all the entries whose URL is specified.
|
|
||||||
|
|
||||||
Browser integration must be enabled on KeePassXC (Tools menu -> Settings) specifying which browsers you intend to use:
|
|
||||||
|
|
||||||
![][8]
|
|
||||||
|
|
||||||
Once the extension is installed, it is necessary to create a connection with the database. To do this, press the extension button and then the Connect button: if the database is open and unlocked the extension will create an association key and save it in the database, the key is unique to the browser so I suggest naming it appropriately :
|
|
||||||
|
|
||||||
![][9]
|
|
||||||
|
|
||||||
When you reach the login page specified in the Url field and the database is unlocked, the extension will offer you all the credentials you have associated with that page:
|
|
||||||
|
|
||||||
![][10]
|
|
||||||
|
|
||||||
In this way, browsing with KeePassXC running you will have your internet credentials available without necessarily saving them in the browser.
|
|
||||||
|
|
||||||
### SSH agent integration
|
|
||||||
|
|
||||||
Another interesting feature of KeePassXC is the integration with SSH. If you have ssh-agent running KeePassXC is able to interact and add the ssh keys that you have uploaded as attachments to your entries.
|
|
||||||
|
|
||||||
First of all in the general settings (Tools menu -> Settings) you have to enable the ssh agent and restart the program:
|
|
||||||
|
|
||||||
![][11]
|
|
||||||
|
|
||||||
At this point it is required to upload your ssh key pair as an attachment to your entry. Then in the “SSH agent” tab select the private key in the attachment drop-down list, the public key will be populated automatically. Don’t forget to select the two checkboxes above to allow the key to be added to the agent when the database is opened / unlocked and removed when the database is closed / locked:
|
|
||||||
|
|
||||||
![][12]
|
|
||||||
|
|
||||||
Now with the database open and unlocked you can log in ssh using the keys saved in your wallet.
|
|
||||||
|
|
||||||
The only limitation is in the maximum number of keys that can be added to the agent: ssh servers do not accept by default more than 5 login attempts, for security reasons it is not recommended to increase this value.

使用 KeePassXC 管理凭据
|
||||||
|
======
|
||||||
|
|
||||||
|
![][1]
|
||||||
|
|
||||||
|
[上一篇文章][2]我们讨论了使用服务器端技术的密码管理工具。这些工具非常有趣而且适合云安装。在本文中，我们将讨论 KeePassXC，这是一个简单的多平台开源软件，它使用本地文件作为数据库。
|
||||||
|
|
||||||
|
这种密码管理软件的主要优点是简单。无需服务器端技术专业知识，因此可供任何类型的用户使用。
|
||||||
|
|
||||||
|
### 介绍 KeePassXC
|
||||||
|
|
||||||
|
KeePassXC是一个开源的跨平台密码管理器：它是作为 KeePassX 的一个分支开始开发的，这是个不错的产品，但开发不是非常活跃。它使用 256 位密钥的 AES 算法将密钥保存在加密数据库中，这使得在云端设备（如 pCloud 或 Dropbox）中保存数据库相当安全。
|
||||||
|
|
||||||
|
除了密码，KeePassXC 还允许你在加密钱包中保存各种信息和附件。它还有一个有效的密码生成器，可以帮助用户正确地管理他的凭据。
|
||||||
|
|
||||||
|
### 安装
|
||||||
|
|
||||||
|
这个程序在标准的 Fedora 仓库和 Flathub 仓库中都有。不幸的是，沙箱程序无法使用浏览器集成，所以我建议通过 dnf 安装程序：
|
||||||
|
```
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
sudo dnf install keepassxc
|
||||||
|
```
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
### 创建你的钱包
|
||||||
|
|
||||||
|
要创建新数据库，有两个重要步骤：
|
||||||
|
|
||||||
|
* 选择加密设置：默认设置相当安全，增加转换轮次也会增加解密时间。
|
||||||
|
* 选择主密钥和额外保护：主密钥必须易于记忆（如果丢失它，你的钱包就会丢失！）但是足够强大，一个至少有 4 个随机单词的密码可能是一个不错的选择。作为额外保护，你可以选择密钥文件（请记住：你必须始终都有它，否则无法打开钱包）和/或 YubiKey 硬件密钥。
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
![][3]
|
||||||
|
|
||||||
|
![][4]
|
||||||
|
|
||||||
|
数据库文件将保存到文件系统。如果你想与其他计算机/设备共享，可以将它保存在 U 盘或 pCloud 或 Dropbox 等云存储中。当然，如果你选择云存储，建议使用特别强大的主密码，如果有额外保护则更好。
|
||||||
|
|
||||||
|
### 创建你的第一个条目
|
||||||
|
|
||||||
|
创建数据库后，你可以开始创建第一个条目。对于 Web 登录，请在“条目”选项卡中输入用户名、密码和 URL。 你可以根据个人策略指定凭据的到期日期，也可以通过按右侧的按钮下载网站的 favicon 并将其关联为条目的图标，这是一个很好的功能。
|
||||||
|
|
||||||
|
![][5]
|
||||||
|
|
||||||
|
![][6]
|
||||||
|
|
||||||
|
KeePassXC 还提供了一个很好的密码/口令生成器，你可以选择长度和复杂度，并检查对暴力攻击的抵抗程度：
|
||||||
|
|
||||||
|
![][7]
|
||||||
|
|
||||||
|
### 浏览器集成
|
||||||
|
|
||||||
|
KeePassXC 有一个适用于所有主流浏览器的扩展。该扩展允许你填写所有已指定 URL 条目的登录信息。
|
||||||
|
|
||||||
|
必须在 KeePassXC（工具菜单 -> 设置）上启用浏览器集成，指定你要使用的浏览器：
|
||||||
|
|
||||||
|
![][8]
|
||||||
|
|
||||||
|
安装扩展后，必须与数据库建立连接。要执行此操作，请按扩展按钮，然后按“连接”按钮：如果数据库已打开并解锁，那么扩展程序将创建关联密钥并将其保存在数据库中，该密钥对于浏览器是唯一的，因此我建议对它适当命名：
|
||||||
|
|
||||||
|
![][9]
|
||||||
|
|
||||||
|
当你打开 URL 字段中的登录页并且数据库是解锁的，那么这个扩展程序将为你提供与该页面关联的所有凭据：
|
||||||
|
|
||||||
|
![][10]
|
||||||
|
|
||||||
|
通过这种方式，你可以通过 KeePassXC 获取互联网凭据，而无需将其保存在浏览器中。
|
||||||
|
|
||||||
|
### SSH agent integration
|
||||||
|
|
||||||
|
KeePassXC 的另一个有趣功能是与 SSH 集成。如果你使用 ssh 代理，KeePassXC 能够交互并添加你上传的 ssh 密钥到条目中。
|
||||||
|
|
||||||
|
首先，在常规设置（工具菜单 -> 设置）中，你必须启用 ssh 代理并重启程序：
|
||||||
|
|
||||||
|
![][11]
|
||||||
|
|
||||||
|
此时，你需要作为附件上传你的 ssh 密钥对到条目中。然后在 “SSH agent” 选项卡中选择附件下拉列表中的私钥，此时公钥将自动填充。不要忘记选择上面的两个复选框，以便在数据库打开/解锁时将密钥添加到代理，并在数据库关闭/锁定时删除：
|
||||||
|
|
||||||
|
![][12]
|
||||||
|
|
||||||
|
现在打开和解锁数据库，你可以使用钱包中保存的密钥登录 ssh。
|
||||||
|
|
||||||
|
唯一的限制是可以添加到代理的最大密钥数：ssh 服务器默认不接受超过5次登录尝试，出于安全原因，建议不要增加此值。
