Currently, Raspbian OS features OpenSSL v1.0.1 which does not support the cipher algorithms required to run some SDK examples. Therefore, you must replace the OpenSSL with a version that has been compiled with the required ciphers. This user guide will help you to compile OpenSSL v1.1.0 on the Raspberry Pi board.

To complete this procedure, run the commands provided in the steps below.

Installing the required software

        sudo apt-
        
         get
        
        update
       

        sudo apt-
        
         get
        
        install build-essential git
       

Cloning the OpenSSL project

Clone the following Git repository:

        git clone https:
        
         //github.com/openssl/openssl.git -b OpenSSL_1_1_0-stable --depth 1
        
       

Building the library

        cd openssl
       

       

        ./config shared --release
       

        make -j5
       

        sudo make install
       

Copying the libraries

        sudo cp libssl.so* /usr/lib/arm-linux-gnueabihf/
       

        sudo cp libcrypto.so* /usr/lib/arm-linux-gnueabihf/
       

Verifying the OpenSSL version

        openssl version
