For symmetic encryption, you can use the following:

To encrypt:
openssl aes-256-cbc -salt -a -e -in plaintext.txt -out encrypted.txt

To decrypt:
openssl aes-256-cbc -salt -a -d -in encrypted.txt -out plaintext.txt


For Asymmetric encryption you must first generate your private key and extract the public key.

Raspberry Pi Raspbian 64bit headless setup

A step-by-step guide for running a headless Raspbian 64bit kernel and OS on Raspberry Pi. The provided configuration has been tested on models 3B, 3B+ and 4B.

Instructions

1. Download the Raspberry Pi Imager application.

2. Use the application to download Raspbian Lite (under Raspbian (other)) and write the image on your SD card.

3. Setup wireless connection configuration by creating wpa_supplicant.conf file in the boot folder:

SonarQube does currently not support Raspberry PI. 

This is a workaround. It compiles a armv6 compatible version of the java-wrapper and configures sonarqube to use it. 

(Testet with Raspbian, wheezy, 3.6)

Compile java-wrapper for ARMv6
============================
Download latest version of " wrapper_prerelease_XY.tar" from http://wrapper.tanukisoftware.com/downloads/ (for me 3.5.17 works)
