 To ensure the integrity and secure source of OpenHarmony applications, the applications must be signed during the build process. Only signed applications can be installed, run, and debugged on real devices. [developtools_hapsigner](https://gitee.com/openharmony/developtools_hapsigner) provides the source code of the OpenHarmony Ability Package (HAP) signing tool - hapsigner. This tool can be used to generate key pairs, certificate signing requests (CSRs), certificates, profile signatures, and HAP signatures.
