Encryption is mostly used to remove clear passwords from settings (database or SCM credentials for instance). The implemented solution is based on a symetric key algorithm. The key point is that the secret key is stored in a secured file on disk. This file must owned by and readable only by the system account that runs the SonarQube server, the analysis with SonarQube Runner, SonarQube Ant Task, Maven or from the Continuous Integration server.
The algorithm is AES 128 bits. Note that 256 bits cipher is not used because it's not supported by default on all Java Virtual Machines (see this article).
1. Generate the secret key
A unique secret key must be shared between all parts of the SonarQube infrastructure (server and analyzers). To generate it, go to Administration > Configuration > Encryption and click on Generate Secret Key:
2. Store the secret key on the SonarQube server
Copy the generated secret key to a file:
sonar-secret.txtbIOVA1TybepjqLH+uYxuNh==
Store this file on the machine hosting the SonarQube server (default location:
~/.sonar/sonar-secret.txt
). If you want to store it somewhere else, set its path through thesonar.secretKeyPath
property in SONARQUBE_HOME/conf/sonar.properties:SONARQUBE_HOME/conf/sonar.properties... # On Linux sonar.secretKeyPath=/path/to/my/secure/location/my_secret_key.txt # On Windows # (use / or \\ as directory separator) sonar.secretKeyPath=C:/path/to/my/secure/location/my_secret_key.txt ...
- Restrict its access to the system account running the SonarQube server (ownership and read-access only).
- Restart your SonarQube server.
3. Generate the encrypted values of your settings
Go back to Administration > Configuration > Encryption and generate the encrypted values of your settings:
4. Use these encrypted values in SonarQube server configuration
Simply copy these encrypted values into SONARQUBE_HOME/conf/sonar.properties:
sonar.jdbc.url=jdbc:oracle:thin:@172.16.199.130/XE sonar.jdbc.username=sonar sonar.jdbc.password={aes}CCGCFg4Xpm6r+PiJb1Swfg== # Encrypted password for the database ... sonar.secretKeyPath=C:/path/to/my/secure/location/my_secret_key.txt
Restart your SonarQube server.
