Convert OpenSSH ed25519 Private Key to OpenSSH Format for MySQL Workbench
OpenSSH is a widely used secure remote login protocol that uses public key cryptography for authentication. One of the key types used in OpenSSH is ed25519, which is a modern, fast, and secure elliptic curve-based algorithm. This article will guide you through the process of converting an OpenSSH ed25519 private key to OpenSSH format, which is compatible with MySQL Workbench.
Understanding OpenSSH ed25519 Private Key
An OpenSSH ed25519 private key is a file that contains the private key information used for authentication in OpenSSH. The private key is kept secret and should be protected. The private key file has the following structure:
-----BEGIN OPENSSH PRIVATE KEY-----
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-----END OPENSSH PRIVATE KEY-----
Converting OpenSSH ed25519 Private Key to OpenSSH Format
To convert an OpenSSH ed25519 private key to OpenSSH format, you can use the OpenSSH ssh-keygen command with the -m option. The -m option specifies the format of the key to be written. In this case, we want to convert the key to OpenSSH format, so we use the value PEM.
Here is an example command to convert an OpenSSH ed25519 private key to OpenSSH format:
ssh-keygen -p -N '' -m PEM -f /path/to/ed25519_private_key
In this command:
-p: prompts for a new passphrase-N '': sets the passphrase to an empty string (no passphrase)-m PEM: specifies the format of the key to be written as PEM (OpenSSH format)-f /path/to/ed25519_private_key: specifies the path to the OpenSSH ed25519 private key file
After running this command, you will be prompted to enter the current passphrase for the private key. After entering the passphrase, the private key will be converted to OpenSSH format and saved to the same file.
Using OpenSSH Private Key in MySQL Workbench
After converting the OpenSSH ed25519 private key to OpenSSH format, you can use it in MySQL Workbench for remote database connections. Here are the steps to use the private key in MySQL Workbench:
- Open MySQL Workbench and go to the
Preferenceswindow - Go to the
SSHtab - Click on the
Newbutton to create a new SSH key - Enter a name for the key and select the private key file
- Click on the
Savebutton to save the key - Go to the
Connectionwindow and select the SSH tunnel option - Select the SSH key that you created in step 3
- Enter the hostname and port for the remote MySQL server
- Click on the
Connectbutton to establish the SSH tunnel and connect to the remote MySQL server
In this article, we covered the process of converting an OpenSSH ed25519 private key to OpenSSH format for use in MySQL Workbench. We discussed the structure of the OpenSSH ed25519 private key file and provided an example command to convert the key to OpenSSH format using the OpenSSH ssh-keygen command. We also discussed the steps to use the private key in MySQL Workbench for remote database connections.
