Choose the agent certificate format that matches your client programming language. You can download the agent certificate from dualshield in the following formats:
To download a PEM format certificate, in the Agents list, click the context menu of your agent and select "Downloads | Agent Certificate (PEM)". The certificate will be saved as "API.pem". This PEM certificate contains both the certificate and the private key.

If you are using some programming language, like python, you might want to extract the private key separately. You can use the OpenSSL tool:
openssl rsa -in API.pem -out apikey.pem
apikey.pem is the certificate's unencrypted private key.
To download a PKCS12 format certificate, select "Downloads | Agent Certificate (PFX)". The certificate will be saved as "API.pfx". The agent password will be used to protect the pfx certificate.

if your application code is in JAVA, you can download a JKS store directly by selecting "Downloads | Agent SSL Certificate (JKS)". The certificate will be saved as "API.jks".
