### Security
By default, Harbor uses HTTPS for secure communication. A self-signed certificate is generated at first boot. A Docker client or a VCH (Virtual Container Host) needs to trust the certificate of Harbor's CA in order to interact with Harbor.
Harbor uses HTTPS for secure communication by default. A self-signed certificate is generated at first boot based on its FQDN (Fully Qualified Domain Name) or IP address. A Docker client or a VCH (Virtual Container Host) needs to trust the certificate of Harbor's CA (Certificate Authority) in order to interact with Harbor.
The self-generated certificate can be replaced by supplying a certificate signed by other CAs in OVA's settings.
Harbor always tries to generate a self-signed certificate based on its FQDN. Therefore, its IP address must have a FQDN associated with it in the DNS server. If Harbor cannot resolve its IP address to a FQDN, it generates the self-signed certificate using its IP address. In this case, Harbor can only be accessed by IP address. When Harbor's IP address or FQDN is changed, the self-signed certificate will be re-generated.
Harbor's self-generated certificate can be replaced by supplying a certificate signed by other CAs in OVA's settings.
Harbor can be configured to use plain HTTP for some environments such as testing and continuous integration (CI). However, it is **NOT** recommended to use HTTP for production because the communication is never secure.
### Networking
Harbor can obtain IP address by DHCP. This is convenient for testing purpose. For a production system, it is recommended that static IP address and host name be used.
Harbor can obtain IP address by DHCP. This is convenient for testing purpose. For a production system, it is recommended that static IP address and FQDN be used.
For the purpose of generating a self-signed certificate, it is recommended that a DNS record be added to associate Harbor's IP address with a FQDN. This is necessary for both static IP address and dynamic IP address acquired from DHCP. If a DNS record is missing for Harbor's IP address, Harbor can only be accessed by its IP address.

4. Copy the certificate file to a Docker host, put it under the below directory. Replace **host_name_or_IP_of_Harbor** with the actual host name or IP address of Harbor instance. You may need to create the directory if it does not exist:
4. Copy the certificate file `ca.crt` to a Docker host. To access Harbor using its FQDN, run the below commands, replace `<Harbor_FQDN>` with the actual FQDN of the Harbor instance:
```
/etc/docker/certs.d/host_name_or_IP_of_Harbor/ca.crt
mkdir -p /etc/docker/certs.d/<Harbor_FQDN>
cp ca.crt /etc/docker/certs.d/<Harbor_FQDN>/
```
5. Restart Docker service.
6. Run `docker login` to verify that HTTPS is working.
To access Harbor using its IP address, run the below commands, replace `<Harbor_IP>` with the actual IP address of the Harbor instance:
```
mkdir -p /etc/docker/certs.d/<Harbor_IP>
cp ca.crt /etc/docker/certs.d/<Harbor_IP>/
```
**Note:** If you run the above two sets of commands, Harbor can be accessed by both FQDN and IP address.
5. Run `docker login` command to verify that HTTPS is working.
To import the CA's certificate into VCH, complete Step 1-3 and refer to VCH's document for instructions.

2. The initial admin password, root password of the virtual appliance, MySQL root password, and all networking properties can not be modified using this method after Harbor's first launch. Modify them by the following approach:
* **Harbor Admin Password**: Change it in Harbor admin portal.
* **Root Password of Virtual Appliance**: Change it by logging in the virtual appliance and doing it in the Linux operating system.
* **MySQL Root Password**: Change it by logging in the virtual appliance and doing it in the Linux operating system.
