--   **OpenHarmony Application Self-Signing**
-
-After an OpenHarmony application is compiled, it needs to be signed. The signature will be verified during the application installation.
-
-Self-signing requires the application HAP, profile (*.p7b), self-signed certificate (*.cer), and public-private key pair (*.jks).
-
-1.  The self-signed certificate and public-private key pair are stored in the tools repository.
-
-2.  The application profile is stored in the code directory.
-
-3.  The application HAP is generated during application compilation.
-
-4.  The signing command is integrated into the compilation process. The following is an example:
-
-java -jar hapsigntoolv2.jar sign -mode localjks -privatekey "OpenHarmony Software Signature" -inputFile camera.hap -outputFile signed_camera.hap -signAlg SHA256withECDSA -keystore OpenHarmony.jks -keystorepasswd 123456 -keyaliaspasswd 123456 -profile camera_release.p7b -certpath OpenHarmony.cer -profileSigned 1
-
-Key fields:
-
--jar: signing tool, which is hapsigntoolv2.jar stored in the tools directory
-
--mode: local signature flag, which is fixed at localjks
-
--privatekey: alias of the public-private key pair, which is OpenHarmony Software Signature
-
--inputFile: application to be signed
-
--outputFile: signed application
-
--signAlg: signing algorithm, which is fixed at SHA256withECDSA
-
--keystore: public-private key pair used for signing the application
-
--keystorepasswd: password of the public-private key pair, which is 123456
-
--keyaliaspasswd: password of the public-private key pair alias, which is 123456
-
--profile: application profile, which is stored in the code directory
-
--certpath: self-signed certificate
-
--profileSigned: whether the signing block contains the profile, which is fixed at 1
