Copy the server certificate

You need a server certificate to support HTTPS connections. QRadar supports certificates with the .crt, .cert, or .der file extensions.

To copy a certificate to the /opt/qradar/conf/trusted_certificates directory, choose one of the following options:

Manually copy the certificate to the /opt/qradar/conf/trusted_certificates directory by using SCP or SFTP.
Use SSH to log in to the QRadar Console or managed host and retrieve the certificate by typing the following command:
```
/opt/qradar/bin/getcert.sh <IP or Hostname for RabbitMQ> <Port for RabbitMQ>
```
A certificate is downloaded from the specified host name or IP address and placed into the /opt/qradar/conf/trusted_certificates directory in the appropriate format.
