TLS/DTLS implementation for Flespi using OpenSSL
Flespi is a server platform that supports Teltonika devices, with this platform, you can easily perform POCs such as sensor integration, firmware testing, capturing RAW data, and more. Because of this utility, we will use the Flespi platform as a test server. OpenSSL is open-source software with an Apache-style license, which can be used personally or commercially for free. These tools will be combined to implement TLS/DTLS encryption functionality in our Telematics devices.
Note: TLS/DTLS encryption is one of the security features of Teltonika Telematics, It protects private and sensitive information from eavesdroppers and hackers by encrypting data sent over the network.
