Configuring SSH and SSL

Connect to a database with SSL

1. In the Database tool window (View | Tool Windows | Database), click the Data Source Properties icon .

2. On the Data Sources tab, select a data source that you want to modify.

3. Click the SSH/SSL tab and select the Use SSL checkbox.

4. In the CA file field, navigate to the CA certificate file (for example, mssql.pem).

5. In the Client certificate file field, navigate to the client certificate file (for example, client-cert.pem).

6. In the Client key file field, navigate to the client key file (for example, client-key.pem).

7. From the Mode list, select the verification mode:

   • Require: verifies that the server accepts SSL connections for this IP address and recognizes the client certificate.

   • Verify CA: verifies the server by checking the certificate chain up to the root certificate that is stored on the client.

   • Full Verification: verifies the server host to ensure that it matches the name stored in the server certificate. The SSL connection fails if the server certificate cannot be verified.

8. To ensure that the connection to the data source is successful, click Test Connection.

   

Disable SSL connection to a database

1. In the Database tool window (View | Tool Windows | Database), click the Data Source Properties icon .

2. On the Data Sources tab, select a data source that you want to modify.

3. Click the SSH/SSL tab and clear the Use SSL checkbox.

4. Click Apply.

Copy SSL settings from other data sources

If you configured SSL settings for one data source, you can copy them for another data source.

1. In the Database tool window (View | Tool Windows | Database), click the Data Source Properties icon .

2. On the Data Sources tab, select a data source that you want to modify.

3. Click the SSH/SSL tab and select the Use SSL checkbox.

4. Click the Copy from … link and select the configuration that you want to copy.

Connect to a database with SSH

1. In the Database tool window (View | Tool Windows | Database), click the Data Source Properties icon .

2. Select a data source profile where you want to change connection settings.

3. Click the SSH/SSL tab and select the Use SSH tunnel checkbox.

4. Click the Add SSH configuration button ().

5. In the SSH dialog, click the Add button.

6. If you do not want to share the configuration between projects, select the Visible only for this project checkbox.

7. In Host, Username, and Port fields, specify your connection details.

8. From the Authentication type list, you can select an authentication method:

   • Password: to access the host with a password. To save the password in PyCharm, select the Save password checkbox.

   • Key pair (OpenSSH or PuTTY): to use SSH authentication with a key pair. To apply this authentication method, you must have a private key on the client machine and a public key on the remote server. PyCharm supports private keys that are generated with the OpenSSH utility.

     Specify the path to the file where your private key is stored and type the passphrase (if any) in the corresponding fields. To have PyCharm remember the passphrase, select the Save passphrase checkbox.

   • OpenSSH config and authentication agent: to use SSH keys that are managed by a credentials helper application (for example, Pageant on Windows or ssh-agent on macOS and Linux).

   

Disable SSH connection to a database

1. In the Database tool window (View | Tool Windows | Database), click the Data Source Properties icon .

2. Select a data source profile where you want to change connection settings.

3. Click the SSH/SSL tab and clear the Use SSH tunnel checkbox.

4. Click Apply.

Create the SSH tunnel with PuTTY (Windows)

1. Download and run the latest version of the PuTTY SSH and Telnet client (download the client from https://www.putty.org/).

2. In the PuTTY Configuration dialog, navigate to Connection | SSH | Auth.

3. In the Private key file for authentication field, specify the path to your private key file and click Open.

4. In the command line window, specify the username that you use for the SSH tunnel and press Enter. Do not close the command line window.

5. In the Database tool window (View | Tool Windows | Database), click the Data Source Properties icon on the toolbar.

6. Select a data source profile where you want to change connection settings.

7. Click the SSH/SSL tab and select the Use SSH tunnel checkbox.

8. From the Auth type list, select OpenSSH config and authentication agent.

9. In Proxy host, Proxy user, and Port fields, specify connection details.

10. To ensure that the connection to the data source is successful, click Test Connection.

Create the SSH tunnel with Pageant (Windows)

Pageant is an SSH authentication agent for PuTTY, PSCP, PSFTP, and Plink. Pageant stores your private key, and as long as it is running, it provides the unlocked private key to PuTTY or other tools like PyCharm. You can find the Pageant icon in the Windows taskbar.

1. Download the latest version of Pageant (download the client from https://www.putty.org/).

2. In the Windows taskbar, right-click the Pageant icon and select Add Key.

3. In the Select Private Key File dialog, navigate to the private key file (the PPK file) and click Open.

4. (Optional) Enter the private key passphrase and press Enter.

5. In the Database tool window (View | Tool Windows | Database), click the Data Source Properties icon on the toolbar.

6. Select a data source profile where you want to change connection settings.

7. Click the SSH/SSL tab and select the Use SSH tunnel checkbox.

8. From the Auth type list, select OpenSSH config and authentication agent.

9. In Proxy host, Proxy user, and Port fields, specify connection details.

10. To ensure that the connection to the data source is successful, click Test Connection.

Create the SSH tunnel with the ssh-agent (macOS and Linux)

Run all commands for ssh-agent in the command line.

1. Ensure that ssh-agent is running.

   ssh-agent

2. Add your key to the agent (in the following example, the key path is ~/.ssh/id_rsa).

   ssh-add ~/.ssh/id_rsa

3. (Optional) On macOS, you can add -K option to the ssh-add command to store passphrases in your keychain. On macOS Sierra and later, you need to create the config file in ~/.ssh/ with the following text:

   Host *
   UseKeychain yes
   AddKeysToAgent yes
   IdentityFile ~/.ssh/id_rsa

   If you have other private keys in the .ssh directory, add an IdentityFile line for each key. For example, if the second key has the id_ed25519 name, add IdentityFile ~/.ssh/id_ed25519 as an additional line for the second private key.

4. List all added keys.

   ssh-add -L

5. In the Database tool window (View | Tool Windows | Database), click the Data Source Properties icon on the toolbar.

6. Select a data source profile where you want to change connection settings.

7. Click the SSH/SSL tab and select the Use SSH tunnel checkbox.

8. From the Auth type list, select OpenSSH config and authentication agent.

9. In Proxy host, Proxy user, and Port fields, specify connection details.

10. To ensure that the connection to the data source is successful, click Test Connection.
