Create and manage key pair

info

This guide contains information about GPU and NPU instances.
Video transcoding instances are provided in Virtual Machine, for more details refer to Virtual Machine > Manage key pair.

Key pair is a key used to prove credentials when connecting to an instance, consisting of a public key and a private key. Key pairs can be registered and managed to protect instance access information.
The public key is stored in the instance, while the private key is stored and managed by the user. Anyone with the private key can connect to the instance, so it is important to keep the private key in a secure location.
The method of managing key pairs in GPU services is as follows:

Public and Private Keys

Category	Description
Public key	A publicly managed key registered and managed in the instance for access security - Check on GPU > Key Pair menu > [More] icon > View public key
Private key	A key stored and managed by the user to connect to the instance - Required for instance connection (SSH access) - Downloadable only once at creation - Anyone owning the private key can connect to the instance, so be cautious with its security and management

Create key pair

Create key pair

Create a new key pair.

1. Go to KakaoCloud Console > Beyond Compute Service > GPU.

2. Click the [Create key pair] button in the Key Pair menu.

3. Select Create key pair and enter the required information, then click [Create].

   Create key pair

4. Once the key pair is created, the {key pair name}.pem private key file will be automatically downloaded.

   Category	Description
   Name	Enter key pair name - e.g. instance-01_01 - Duplicate Key Pair names within the same project are not allowed.
   Type	Both types consist of a pair of public and private keys - SSH: Authentication key used in systems employing the SSH protocol - X509: Digital certificates used in SSL/TLS protocols, a public key encryption technology (support planned)

Upload existing key

Create a key pair using existing key information.

1. Go to KakaoCloud Console > Beyond Compute Service > GPU.

2. Click the [Create key pair] button in the Key Pair menu.

3. Select Upload existing key for the creation method.

4. Enter the Key information directly in the registration information or upload the Key file by clicking the [Upload file] button.

   Category	Description
   Name	Key pair name - e.g. instance-01_01 - Duplicate key pair names within the same project are not allowed
   Type	Both types consist of a pair of public and private keys - SSH: Authentication key used in systems employing the SSH protocol - X509: Digital certificates used in SSL/TLS protocols, a public key encryption technology (coming soon)
   Registration	Upload file: Register the downloaded key file - Supported extensions: pub, crt, cer, der, pem, p7b, p7c, pfx, p12 - Enter the content of the key file directly in the Enter directly box.
