About the SSH-Key Generator

What is an SSH-Key Generator?

An SSH-Key Generator is a tool that creates secure public and private key pairs used for SSH (Secure Shell) authentication. These keys enable encrypted communication between a client and a server, commonly used in remote server management and secure file transfers.

How does the SSH-Key Generator work?

The tool generates a pair of cryptographic keys:
Private Key: Kept secret and stored securely.
Public Key: Shared with the server to enable authentication.
These keys are typically created using algorithms like RSA, ECDSA, or Ed25519.

Is the SSH-Key Generator tool secure?

Yes, our tool runs over a secure HTTPS connection. We do not store your input or generated keys.

Which algorithms does the tool support?

Commonly supported algorithms include:
RSA: Standard and widely supported.
ECDSA: Elliptic Curve Digital Signature Algorithm.
Ed25519: A faster and more secure modern alternative.

Why do I need an SSH key pair?

SSH keys eliminate the need for password-based authentication, offering enhanced security through encryption, protection against brute force attacks and easier automation for scripts and DevOps workflows.

How do I use the generated SSH keys?

Add the public key to the server’s ~/.ssh/authorized_keys file.
Use the private key to authenticate with the server using an SSH client.

Can I customize the key generation process?

Yes, our SSH-Keygen tool allows you to specify:
Key length (e.g., 2048 or 4096 bits for RSA).
Key comment to identify the key’s purpose.
Passphrase for additional security.

What is a passphrase, and should I use one?

A passphrase adds an extra layer of security by encrypting your private key. Even if the private key is stolen, the passphrase ensures it cannot be used without decryption.

Can this tool generate keys for Git or cloud services?

Yes, SSH keys generated with this tool can be used for Git services like GitHub, GitLab, and Bitbucket and cloud platforms like AWS, Azure, and Google Cloud.

How to use SSH Keys

Learn how to use SSH keys to authenticate yourself to your server.

  1. Generate an SSH Key Pair

    Use the SSH-Key Generator tool and select your preferred options:
    Algorithm: RSA (4096 bits, recommended for strong security).
    Passphrase: Optional but adds extra protection.
    Key Comment: For identification, e.g., user@example.com.
    Click the Generate button to create the key pair.

  2. Save the Keys

    The tool will provide:
    Private Key: Save this securely, e.g., in ~/.ssh/id_rsa.
    Public Key: Save or copy this, e.g., in ~/.ssh/id_rsa.pub.

  3. Add the Public Key to the Server

    Copy the public key to the server you want to access:
    ssh-copy-id user@remote-server
    Alternatively, manually append the public key to the server’s ~/.ssh/authorized_keys file.

  4. Authenticate Using the Private Key

    Connect to the server with the private key:
    ssh -i ~/.ssh/id_rsa user@remote-server

Example Use Case: Setting Up GitHub Access

  1. Generate an SSH key using the tool.
  2. Copy the public key.
  3. Add the key to your GitHub account under Settings > SSH and GPG keys > New SSH key.
  4. Test the connection:
Bash
ssh -T git@github.com  

By following these steps, you can securely generate and use SSH keys for remote access, Git integration, or other secure applications.
