Some services (such as OpenVPN, MQTT, etc.) on Teltonika Networks devices can be secured using TLS for encryption and authentication. This page discusses where one can obtain TLS certificates and key for this purpose.
Certificate generation
If you are using a third party service that requires TLS, all necessary files should be provided by the provider of that service. However, if you are setting up your own solution you may find use in of the TLS certificate generation methods described below.
Teltonika Networks device
The easiest way to generate certificates and keys is by using the Certificate Generation page that is available in the device's WebUI:
- System → Administration → Certificates
Certificate of Authority (CA)
The first step is to generate a Certificate Authority (CA) certificate, which will be used to sign both server and client certificates.
- Choose the file type as CA.
- On Teltonika routers, users can select from four Key Size options, ranging from 512 bits to 4096 bits.
- Enter the Common Name. This usually represents the fully qualified domain name (FQDN) of the server (e.g., example.com), but it can be any name of your choice.
- By enabling Subject Information, you can provide details about the entity to which the certificate is issued (Optional):
- A. Country Code (CC): The two-letter country code (e.g., LT for Lithuania).
- B. State or Province Name (ST): The name of the state or province (e.g., California).
- C. Locality Name (L): The city or locality (e.g., San Francisco).
- D. Organization Name (O): The name of the organization or company (e.g., Teltonika).
- E. Organizational Unit Name (OU): The name of the department or unit within the organization (e.g., IT Department).
- These fields help to clearly identify the organization or individual associated with the certificate.
- Select the "On" option next to "Sign the Certificate." If not enabled, the Root CA will not sign or generate the new CA.
- Enter the period of how long CA certificate will be valid
- "Delete Signing Request" can be enabled, as it is not required after generation.
- Click

You can also use third party software to generate the certificates on your computer. Guides are available for:
