hapsigner Guide

Build

Check that Gradle 7.1 has been installed.
```
gradle -v
```
Download the code, open the file directory developtools_hapsigner/hapsigntool, and run the following command to build the code:
```
gradle build 
```
Or
```
gradle jar
```
Check that hap-sign-tool.jar (binary files) is generated in the ./hap_sign_tool/build/libs directory.

Usage Guidelines

When to Use

The OpenHarmony system has a built-in KeyStore (KS) file named OpenHarmony.p12. This file contains the root CA certificate, intermediate CA certificate, and end-entity certificate information. The hapsigner tool signs the OpenHarmony applications based on this KS file.

The usage of hapsigner varies depending on whether an application signing certificate is available.

If no application signing certificate is available:
You need to generate a key pair, generate an application signing certificate, sign the profile, and sign the application.
If an application signing certification is available:
You need to sign the profile, and use the application signing certificate and the local KS file (containing the corresponding key) to sign the application.

Signing Procedure

The process of signing a HAP is as follows:

Generate a key pair for an application signing certificate.
Generate an application signing certificate.
Sign the profile.
Sign the HAP.

Precautions

For security purposes, use ECC to generate the key pair in step 1. Do not use RSA.

You are advised to place the HAP to be signed, profile, OpenHarmony.p12, root CA certificate, intermediate CA certificate, and hapsigner in the same directory for easy operation. The developtools_hapsigner/autosign/result directory has the following files:

OpenHarmony KS file: OpenHarmony.p12

Root CA certificate: rootCA.cer

Intermediate CA certificate: subCA.cer

Profile signing certificate: OpenHarmonyProfileRelease.pem

Generate a key pair for the application signing certificate.

Generate a signing key pair and save it to the KS.

Example:

   java -jar hap-sign-tool.jar generate-keypair -keyAlias "oh-app1-key-v1" -keyAlg "ECC"  -keySize "NIST-P-256" -keystoreFile "OpenHarmony.p12" -keyPwd "123456" -keystorePwd "123456"

NOTE

Record the values of keyAlias, keyStorePwd, and keyPwd. These values will be used when the application signing certificate is generated and the HAP is signed.

The command parameters are described as follows:

   generate-keypair: Generate a key pair for the application signing certificate.
       ├── -keyAlias         # Alias of the key used to generate the application signing certificate. It is stored in the OpenHarmony.p12 file. This parameter is mandatory.
       ├── -keyAlg           # Key algorithm. It is mandatory. ECC is recommended.
       ├── -keySize          # Key length. It is NIST-P-256/NIST-P-384 if ECC is used. This parameter is mandatory.
       ├── -keyStoreFile     # KS file. OpenHarmony.p12 is recommended. This parameter is mandatory.
       ├── -keyStorePwd      # KS password. It is mandatory. The default password 123456 for OpenHarmony.p12.
       ├── -keyPwd           # Key password. It is optional. If this parameter is not specified, the generated key pair has no password.

Generate an application signing certificate.

Use the local intermediate CA certificate to issue an application signing certificate.

Example:

   java -jar hap-sign-tool.jar generate-app-cert -keyAlias "oh-app1-key-v1" -signAlg "SHA256withECDSA"  -issuer "C=CN,O=OpenHarmony,OU=OpenHarmony Team,CN= OpenHarmony Application CA" -issuerKeyAlias "openharmony application ca" -subject "C=CN,O=OpenHarmony,OU=OpenHarmony Team,CN=OpenHarmony Application Release" -keystoreFile "OpenHarmony.p12" -subCaCertFile "subCA.cer" -rootCaCertFile "rootCA.cer" -outForm "certChain" -outFile "app1.pem" -keyPwd "123456" -keystorePwd "123456" -issuerKeyPwd "123456" -validity "365"

FAQs

When the application signing certificate is generated, the console displays the result but no file is output.
- Symptom
When the tool is used to generate an application signing certificate, the certificate content is displayed on the console and no certificate is generated.
- Possible Causes
The path in the outFile parameter is incorrect, or the hyphen (-) in -outFile is not an English character.
- Solution
Check and correct the value of outFile, and ensure the hyphen (-) in -outFile is an English character.
Failed to sign the profile.
- Symptom
When the tool is used to sign a profile, any of the following information is displayed:

(1) "SIGN_ERROR, code: 107. Details: Failed to verify signature: Wrong key usage"

(2) "NOT_SUPPORT_ERROR, code: 105. Details: Profile cert 'result\profile1.pem' must a cert chain"

(3) "VERIFY_ERROR, code: 108. Details: Failed to verify signature: unable to find valid certification path to requested target"
- Possible Causes
(1) The certificate chain of the profile signing certificate is in incorrect order.

(2) The profile signing certificate is not a certificate chain.

(3) The certificate subject is in incorrect sequence, or the -issuerKeyAlias parameter set to generate the application signing certificate is incorrect.
- Solution
(1) Check that the certificate chain is in ascending or descending order of seniority.

(2) Check that the certificate is a certificate chain.

(3) Check that the certificate subject is in the C, O, OU, and CN order.
An error message is displayed when the tool is used to sign a HAP.
- Symptom
The following information is displayed after the command is executed:
NOT_SUPPORT_ERROR, code: 105. Details: SignAlg params is incorrect, signature algorithms include SHA256withECDSA,SHA384withECDSA
- Possible Causes
The signing algorithm is not supported. Check the value of signAlg.
- Solution
Use ECC to generate the key pair for the application or profile signing certificate. Use SHA256withECDSA or SHA384withECDSA as the HAP signing algorithm.
