Several tools exist to generate SSH public/private key pairs. The following sections show how to generate an SSH key pair on UNIX, UNIX-like and Windows platforms.

Generating an SSH Key Pair on UNIX and UNIX-Like Platforms Using the ssh-keygen Utility

UNIX and UNIX-like platforms (including Solaris and Linux) include the ssh-keygen utility to generate SSH key pairs.

Nov 15, 2017  In this video, I show you how to setup SSH Keys in Windows with PuttyGen. This allows you to connect to your linux server without having to authenticate with a password. PuTTY does not natively support the private key format for SSH keys. PuTTY provides a tool named PuTTYgen, which converts keys to the required format for PuTTY. You must convert your private key (.pem file) into this format (.ppk file) as follows in order to connect to your instance using PuTTY. Jul 28, 2018  Step 1. Open PuTTYgen tool. This will display 'PuTTY Key Generator' window. PuTTYgen is used to generate the new key file (s) or convert the key file (s). From the 'Load private key:' dialog, select the 'All Files. After clicking OK button, key details are populated in. Download PuTTY. PuTTY is an SSH and telnet client, developed originally by Simon Tatham for the Windows platform. PuTTY is open source software that is available with source code and is developed and supported by a group of volunteers. Alternatively if you want to grab the private and public keys from a PuTTY formated key file you can use puttygen on.nix systems. For most apt-based systems puttygen is part of the putty-tools package. Outputting a private key from a PuTTY formated keyfile: $ puttygen keyfile.pem -O private-openssh -o avdev.pvk. For the public key.

1. Navigate to your home directory:
2. Run the ssh-keygen utility, providing as filename your choice of file name for the private key:

   The ssh-keygen utility prompts you for a passphrase for the private key.

3. Enter a passphrase for the private key, or press Enter to create a private key without a passphrase:

   Note:

   While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.

   The ssh-keygen utility prompts you to enter the passphrase again.

4. Enter the passphrase again, or press Enter again to continue creating a private key without a passphrase:
5. The ssh-keygen utility displays a message indicating that the private key has been saved as filename and the public key has been saved as filename.pub. It also displays information about the key fingerprint and randomart image.

I have generated and downloaded a private.pem key from AWS. However, to use Putty in order to connect to the virtual machine, I must have that key in.ppk format. The process of conversion is deta. Cyberduck is a widely used Mac OS SSH Client. Once PuTTY installed on the Mac OS, a user can convert PuTTY derived private key format to OpenSSH. To convert the private key to standard PEM format, type the following command – puttygen privatekey.ppk-O private-openssh-o privatekey.pem.

Generating an SSH Key Pair on Windows Using the PuTTYgen Program

The PuTTYgen program is part of PuTTY, an open source networking client for the Windows platform.

1. Download and install PuTTY or PuTTYgen.

   To download PuTTY or PuTTYgen, go to http://www.putty.org/ and click the You can download PuTTY here link.

2. Run the PuTTYgen program.
3. Set the Type of key to generate option to SSH-2 RSA.
4. In the Number of bits in a generated key box, enter 2048.
5. Click Generate to generate a public/private key pair.

   As the key is being generated, move the mouse around the blank area as directed.

6. (Optional) Enter a passphrase for the private key in the Key passphrase box and reenter it in the Confirm passphrase box.

   Note:

   While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.

7. Click Save private key to save the private key to a file. To adhere to file-naming conventions, you should give the private key file an extension of .ppk (PuTTY private key).

   Note:

   The .ppk file extension indicates that the private key is in PuTTY's proprietary format. You must use a key of this format when using PuTTY as your SSH client. It cannot be used with other SSH client tools. Refer to the PuTTY documentation to convert a private key in this format to a different format.
8. Select all of the characters in the Public key for pasting into OpenSSH authorized_keys file box.

   Make sure you select all the characters, not just the ones you can see in the narrow window. If a scroll bar is next to the characters, you aren't seeing all the characters.

9. Right-click somewhere in the selected text and select Copy from the menu.
10. Open a text editor and paste the characters, just as you copied them. Start at the first character in the text editor, and do not insert any line breaks.
11. Save the text file in the same folder where you saved the private key, using the .pub extension to indicate that the file contains a public key.
12. If you or others are going to use an SSH client that requires the OpenSSH format for private keys (such as the ssh utility on Linux), export the private key:
    1. On the Conversions menu, choose Export OpenSSH key.
    2. Save the private key in OpenSSH format in the same folder where you saved the private key in .ppk format, using an extension such as .openssh to indicate the file's content.

To make a connection to a database more secure, some services require SSH or SSL usage.

SSL

The following procedure describes the SSL configuration that suits most databases. For some databases, you need to use another approach for a successful connection. You can see configuration examples for Cassandra and Heroku Postgres in the DataGrip documentation.

Connect to a database with SSL

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 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.

It is recommended to use PEM certificates.

With self-signed certificates and in some cases with certificates issued by the trusted root entity, you might experience errors when you use the latest JDBC driver version. The SSL connection might fail if your Java keystore does not accept the certificate chains. As a temporary solution, try to downgrade the JDBC driver (for example, for the MySQL connector, you need to switch to the 5.1.40 version.)

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

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.

SSH

Secure Shell or SSH is a network protocol that is used to encrypt a connection between a client and a server.

All created SSH connections are shared between all the data sources that you have in a project. If you do not want to share a connection between projects, select the Visible only for this project checkbox in the SSH connection settings.

Connect to a database with SSH

1. In the Database tool window (View Tool Windows Database), click the Data Source PropertiesVmware esxi 6 key generator. 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, User name, and Port fields, specify your connection details.

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

   • Password: to access the host with a password. To save the password in RubyMine, 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. RubyMine 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 RubyMine 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).

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

See the Generating a new SSH key and adding it to the ssh-agent tutorial for details on working with SSH keys.

Ssh Pem File

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.
