as it uses mbedtls, please make sure that is uses the new psa crypto api, as zephyr is soon switching to https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-4.0.0 where support for the legacy mbedtls api was dropped. |

This contribution is to add support for SRTP protocol. The original library named libSRTP is developed by Cisco here.
Dependencies for this module are:
libSRTP
mbedTLS
The mbedTLS integration is made by linking its library to the libSRTP. The libSRTP can use different encryption libraries including openSSL, NSS, mbedTLS, etc. As mbedTLS is available for Zephyr RTOS, I used this library.
The original libSRTP needed just a little modification to be used in Zephyr RTOS. Just adding a file
zephyr/module.ymlwith contentcmake-ext: TrueandKconfig-ext: Trueinside it. I pushed the modified repository into my GitHub account.To test the result, for simplicity, I modified rtpw example. To test the sample, I used a PC as a sender/receiver and a Zephyr application as a receiver/sender. The original rtpw sample provided by Cisco only sends/receives text instead of Audio/Image. So, I did the same.
How can I integrate it in Zephyr RTOS as an internal or external module?
