In the world of secure communication, SSH (Secure Shell) is a cornerstone technology, enabling encrypted connections to remote servers. For KDE Plasma users, managing SSH keys and agents can be both secure and seamless, thanks to powerful tools like ksshaskpass, KDE Wallet, and the built-in SSH agent.
This article dives into the essentials of SSH management on KDE Plasma. Whether you’re new to SSH or looking to optimize your workflow, you’ll learn how to create SSH keys, understand the role of KDE Wallet, and leverage ksshaskpass to simplify passphrase handling. By the end of this guide, you’ll have a streamlined and secure SSH setup tailored for KDE Plasma.
Prerequisites
Before diving into the details, make sure you have SSH installed on your system. On most Linux distributions, OpenSSH is the default SSH implementation and can be installed via your package manager. For example
On Arch Linux/EndeavourOS
sudo pacman -S openssh
On Fedora
sudo dnf install openssh
On Debian/Ubuntu
sudo apt install openssh-client
To verify the installation, run the following command
ssh -V
You should see the version of OpenSSH displayed.
Generating a New SSH Key
An SSH key pair consists of a public and private key used for secure authentication. You can generate a new SSH key on your local machine and use it to authenticate with services like GitHub, Gtlab or Codeberg for operations over SSH, or just use it for Authenticate against your server.
Step 1: Open a Terminal
To begin, open your terminal application.
Step 2: Generate the Key
Run the following command to create a new SSH key. Replace the email address in the command with your email, preferably the one linked to your GitHub account or the service you’ll authenticate with:
ssh-keygen -t ed25519 -C "your_email@example.com"
If you’re using an older system that doesn’t support the Ed25519 algorithm (like Azure Devops), you can use RSA instead:
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
What Do These Options Mean?
-t ed25519
or-t rsa
: Specifies the algorithm for the key pair.- Ed25519: A newer, more secure algorithm. It is faster and generates smaller keys, making it ideal for modern systems.
- RSA: An older algorithm, still widely supported but requires longer keys (e.g., 4096 bits) to achieve comparable security to Ed25519.
-b 4096
(for RSA): Specifies the key size in bits. Larger keys provide stronger security but require more computational power.-C "your_email@example.com"
: Adds a label to the key. This label helps identify the key later, especially useful if you manage multiple keys. While an email address is commonly used, the label can be any string that makes sense to you (e.g., “Work SSH Key” or “Username”).
Step 3: Choose a File Location
After running the command, you’ll see the following prompt:
Enter a file in which to save the key (/home/YOU/.ssh/id_ed25519):
Press Enter to save the key to the default location (~/.ssh/id_ed25519
for Ed25519 or ~/.ssh/id_rsa
for RSA). If you already have keys at the default location, you can create a new file name by typing a custom path, such as:
/home/YOU/.ssh/my_custom_key
Step 4: Secure Your Key with a Passphrase
Next, you’ll be prompted to set a passphrase for the private key:
Enter passphrase (empty for no passphrase):
For security, it’s highly recommended to set a passphrase. This ensures that even if your private key is stolen, the attacker would need to know your passphrase to use it.
After entering your passphrase, you’ll confirm it:
Enter same passphrase again:
Key Differences: Ed25519 vs. RSA
- Algorithm Age:
- RSA is a well-established algorithm introduced in 1977.
- Ed25519 is newer and leverages more modern cryptographic techniques, offering similar security with much smaller keys.
- Performance:
- Ed25519 is significantly faster for both signing and verification.
- Key Size:
- RSA requires larger keys (e.g., 2048–4096 bits) for strong security.
- Ed25519 uses fixed 256-bit keys, which are computationally lightweight and secure.
- Compatibility:
- RSA is universally supported, making it suitable for legacy systems.
- Ed25519 is supported on most modern systems and applications.
Why Use a Label?
The label (-C
option) helps you identify the purpose of a key. This is particularly useful when you manage multiple SSH keys. For example:
- GitHub Work Key:
-C "work@example.com"
- Personal Key:
-C "personal@example.com"
- Custom Label:
-C "Project X SSH Key"
You can view labels later to quickly recognize the key’s purpose.
Introduction to SSH Agents
An SSH agent is a program designed to manage your SSH private keys securely and conveniently. Its primary purpose is to store decrypted private keys in memory, allowing you to authenticate multiple SSH sessions without repeatedly entering your passphrase.
Why Use an SSH Agent?
Private keys used for SSH authentication are typically encrypted with a passphrase for security. Each time you want to connect to a remote server or service, you’d need to decrypt the key by entering the passphrase. While this enhances security, it can become cumbersome during frequent or automated operations.
An SSH agent solves this problem by:
- Secure Key Storage: It decrypts your private key once and keeps it securely in memory for the duration of your session.
- Convenience: With the key loaded into the agent, you can initiate SSH connections, perform Git operations, or manage remote servers without re-entering your passphrase.
How It Works
- Key Loading: After you start the SSH agent, you load your private key into it using the
ssh-add
command. During this step, you’ll be prompted to enter your passphrase to decrypt the key. - Authentication Requests: When you connect to a server or perform an SSH operation, the agent provides the necessary credentials (your private key) automatically.
- Session Persistence: The agent keeps your keys in memory until you close the agent or log out, at which point the keys are removed.
Example Workflow
Start the SSH agent
eval $(ssh-agent)
Add your private key to the agent
ssh-add ~/.ssh/id_ed25519
Connect to a remote server
ssh user@remote-server
You won’t need to enter your passphrase again since the agent handles the authentication.
By leveraging an SSH agent, you strike a balance between security and usability, making it an indispensable tool for anyone frequently working with SSH keys.
What is ksshaskpass?
ksshaskpass
is a KDE-specific SSH agent helper designed to integrate seamlessly with the KDE Plasma desktop environment. Its primary function is to provide a graphical interface for entering SSH key passphrases, enhancing the user experience for those who prefer or rely on graphical workflows.
Integration with KDE Plasma
Unlike the standard command-line ssh-agent
workflow, which requires typing passphrases in a terminal, ksshaskpass
integrates directly into KDE Plasma’s graphical environment. When an SSH key’s passphrase is needed, ksshaskpass
triggers a pop-up dialog, allowing you to enter the passphrase in a convenient GUI prompt.
This integration offers:
- System Notifications: KDE Plasma can display system-wide notifications when passphrases are required.
- Session Management: With KDE Wallet enabled,
ksshaskpass
can securely store and manage passphrases, reducing the need for repeated entry.
How It Works
- When an SSH operation requests a passphrase (e.g., connecting to a server or performing a Git operation),
ksshaskpass
intercepts the request. - A graphical dialog appears, prompting you to enter the passphrase.
- Once entered, the passphrase is forwarded to the SSH agent, allowing the operation to proceed.
Why Use ksshaskpass?
- Ease of Use: For users who prefer graphical interfaces,
ksshaskpass
eliminates the need to interact with the terminal for passphrase entry. - Enhanced Usability: Combined with KDE Wallet,

The traditional ssh-agent
approach relies on manual key management via the terminal.
- Starting the Agent: First, you need to start the
ssh-agent
:eval $(ssh-agent)
- Adding Keys: Add your private key to the agent:During this step, you’ll be prompted to enter the passphrase for the key.
ssh-add ~/.ssh/id_ed25519
- Authentication: Once the key is added, you can connect to remote servers or perform SSH operations:
ssh user@remote-server
- Repetition Required: Every time you restart your machine or the agent, you’ll need to repeat these steps unless additional automation is set up (e.g., via a
.bashrc
or.zshrc
script).
KDE Wallet + ksshaskpass Workflow
When using KDE Wallet with ksshaskpass
, the process is streamlined and integrated into KDE Plasma’s graphical environment.
- Initial Key Loading: During the first SSH operation requiring your key,
ksshaskpass
triggers a graphical prompt for your passphrase. - Passphrase Storage: If KDE Wallet integration is enabled, the passphrase is securely stored in the wallet after the initial entry.
- Automatic Key Retrieval: On subsequent SSH operations,
ksshaskpass
fetches the passphrase from KDE Wallet, eliminating the need for manual entry. - Session Management: KDE Wallet can unlock automatically upon login, ensuring that SSH operations are seamless right from the start of your session.
Configuration Examples
Manual ssh-agent
Setup:
- Add the following to your shell’s configuration file (e.g.,
.bashrc
or.zshrc
) to startssh-agent
automatically:
eval $(ssh-agent)
ssh-add ~/.ssh/id_ed25519
2. Restart your shell or source the configuration file:
source ~/.bashrc
KDE Wallet + ksshaskpass Setup:

2. Configure ssh_askpass.conf
Set the SSH_ASKPASS
environment variable to ksshaskpass
and enable its use:
mkdir -p ~/.config/environment.d
vim ~/.config/environment.d/ssh_askpass.conf
Add the following lines:
SSH_ASKPASS=/usr/bin/ksshaskpass
SSH_ASKPASS_REQUIRE=prefer
Restart your session (e.g., log out and log back in) for these changes to take effect.
Optional: Integration with zsh, oh-my-zsh, and Powerlevel10k
If you’ve followed the guide to set up zsh
, oh-my-zsh
, and Powerlevel10k
, you can further enhance your workflow by configuring the ssh
and ssh-agent
plugins instead of the ~/.config/environment.d/ssh_askpass.conf.
vim ~/.zshrc
``````ruby
plugins=(
ssh
ssh-agent
)
zstyle :omz:plugins:ssh-agent helper ksshaskpass
zstyle :omz:plugins:ssh-agent quiet yes
zstyle :omz:plugins:ssh-agent lazy yes
source $ZSH/oh-my-zsh.sh
3. First Time Use
Perform an SSH operation. You will see a graphical prompt for the passphrase. Check the “Remember password” checkbox to store it in KDE Wallet. Future passphrase requests will be handled automatically.
