An SSH keypair is needed to create a cloudlink of the type SFTP. The keypair consists of a private key, which is used in your SFTP client, and a public key, which is uploaded during the creation of an STFP cloudlink in the app B2B Directory.

To create an SSH keypair, follow these steps:

1. Download and install the free tool PuTTY.

   > Go to PuTTYgen

2. Open the PuTTY Key Generator.

3. Set the type of key to RSA or DSA.

4. In the field Number of bits in a generated key, set the length to at least 2048.

5. Click Generate to create the SSH key.

   After the key has been created, it will be visible in the preview.

6. In the field Key comment, enter a description to identify this key.

7. In the fields Key passphrase and Confirm passphrase, enter a password to save your private key.

8. Click Save public key to save the created public key.

9. Click Save private key to save the created private key.
