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
