Worked on the Graylog2/graylog2-server repository to address a security issue in configuration management by correcting the password hashing process. Focused on ensuring that password hashes were generated using the proper SHA-256 algorithm, the developer replaced the incorrect shasum -a 256 command with sha256sum within the configuration files. This adjustment aligned the system with security best practices and reduced the risk of misconfiguration in enterprise deployments. The work was implemented using Shell scripting and configuration management skills, with disciplined change management practices and clear commit traceability to support future audits and maintain the reliability of the deployment process.
