Register and Manage Certificates

Register a Certificate​

To register a certificate to use with the Certificate Manager service:

  1. Go to the KakaoCloud Console > Management > Certificate Manager.

  2. Click the Register Certificate button at the top right of the Certificate tab.

  3. In the Register Certificate popup, enter the following fields.
    Each field must be entered as-is in PEM format text (including headers and footers).

    ① Certificate Private Key

    • The private key paired with the certificate, used to decrypt encrypted communication.
    • Usually provided as .pem or .key files, and should look like: 
      -----BEGIN PRIVATE KEY-----
      (Base64-encoded key)
      -----END PRIVATE KEY-----

    ② Certificate Body

    • The certificate issued by a Certificate Authority (CA).
    • Typically provided as .pem, .crt, or .cer files: 
      -----BEGIN CERTIFICATE-----
      (Base64-encoded certificate content)
      -----END CERTIFICATE-----

    ③ Certificate Chain (Optional)

    • A chain of root and intermediate CA certificates, forming the trust path for clients.
    • Provided as files such as chain.pem or ca-bundle.crt with multiple certificate blocks: 
      -----BEGIN CERTIFICATE-----
      (Intermediate CA certificate)
      -----END CERTIFICATE-----

      -----BEGIN CERTIFICATE-----
      (Root CA certificate)
      -----END CERTIFICATE-----
    caution

    If your certificate files have extensions like .crt, .key, or .cer, make sure their contents are in PEM format text (e.g., -----BEGIN CERTIFICATE-----).
    If the file is in binary (DER format), convert it to PEM using OpenSSL before registering.

  4. Click Register to add the certificate to the list.
