Let's dive into the world of JuiceSSH and SSH keys for secure and streamlined server management on Android.

Understanding JuiceSSH

JuiceSSH is a robust SSH client application specifically designed for Android devices. Given that Android lacks a built-in SSH client, JuiceSSH steps in to offer a secure and feature-rich command-line interface for effectively managing Linux VPS instances. Unlike the common assumption, JuiceSSH provides the valuable capability to generate SSH keys within its interface. This empowers users to create SSH key pairs directly from the application, streamlining the process and enhancing security. Additionally, JuiceSSH allows you to import existing keys generated on your computer. This functionality facilitates the effortless establishment of secure connections to your servers without the need for passwords. By exploring the capabilities of JuiceSSH, including its SSH key generation feature, you will unlock the potential of seamless and secure server management directly from your Android device.

Installing JuiceSSH

To connect to your Linux VPS with SSH keys on your Android device, install JuiceSSH from the Google Play Store.

Generating SSH Keys

Before utilizing JuiceSSH to connect to your Linux VPS securely, you must first generate SSH keys. So, follow these steps:

Open JuiceSSH and navigate to the Manage Connections section.
Swipe to the right to access the Identities page.
Tap the + button located in the lower right corner.
In the New Identity section, assign a descriptive Nickname for your key and input your desired username (e.g., root).

In the Private Key section, tap on SET (OPTIONAL) and select your preferred key format from the available options (ed25519, ECDSA, or RSA).
Enhance the security of your private key by setting a passphrase.
Confirm your choices by tapping on OK.

⚠️ Important: Never share your private key with anyone!

Exporting SSH Public Keys

To export your SSH public keys from JuiceSSH and prepare for their import into the Cloudzy portal (covered in the following section), you can follow these steps:

Open JuiceSSH and go to the Manage Connections section.
Swipe to the right to access the Identities page.
Long-press on the identity that corresponds to the SSH keys you want to export. This identity contains crucial information like SSH Keys and usernames.

Select the option labeled Export Public Key.

Input the passphrase for your Private Key when prompted.
The next steps can vary depending on your preferences. One approach is to send the SSH Public Key contents to your Notes App or email it to yourself. Alternatively, you can choose other methods that are convenient for saving the SSH Public Key contents.

By carrying out these steps, you'll export your SSH public keys from JuiceSSH, enabling you to proceed with their import into the Cloudzy portal in the upcoming section. This process will be integral for securing and streamlining your server management activities.

Importing Your SSH Key to the Cloudzy Portal

Now, import the copied SSH key to the Cloudzy Portal for secure server management:

After copying the SSH key to the clipboard, return to your Cloudzy account page.
In the left sidebar, choose SSH Keys and click on NEW SSH KEY in the top right corner.
Name your key descriptively and paste the SSH Public Key contents into the Public Key area.

With your SSH key successfully imported, you're well-prepared for streamlined VPS creation and heightened server security.

Connecting to Your VPS

To connect to your VPS via JuiceSSH after importing the public key to the Cloudzy Portal, follow these steps:
