DXT builds a multi-layer security protection system: in the distribution process, it verifies the integrity of the .dxt file through SHA-256 and other encryption algorithms to prevent man-in-the-middle attacks; it supports optional digital signature verification at installation time; and it carries out sandbox isolation based on the permissions declared in the manifest.json at runtime to strictly limit the scope of file system/network access. The tool chain also provides dxt verify/dxt sign and other CLI commands, enterprise users can integrate their own CA system to achieve extended signature verification.
