CA证书开发指导

说明

本开发指导需使用API version 12及以上版本SDK。

场景说明

典型场景。

安装用户CA证书。调用者可以将用户CA证书安装在当前用户或者设备公共位置下。
- 安装在当前用户时，仅当前用户的业务可以访问该证书。
- 安装在设备公共位置下，所有用户下的业务都可以访问。
获取用户CA证书列表。可以选择获取当前用户或者设备公共位置下的用户CA证书列表。
获取用户CA证书详情。
删除指定的用户CA证书。
获取CA证书的存储路径。

接口说明

详细接口说明可参考API参考。

以上场景涉及的常用接口如下表所示。

实例名	接口名	描述
certificateManager	installUserTrustedCertificateSync(cert: Uint8Array, certScope: CertScope) : CMResult¹⁸⁺	安装用户CA证书。
certificateManager	uninstallUserTrustedCertificateSync(certUri: string) : void¹⁸⁺	删除用户CA证书。
certificateManager	getAllUserTrustedCertificates(): Promise<CMResult>	获取当前用户和设备公共位置的所有用户根CA证书列表。
certificateManager	getAllUserTrustedCertificates(scope: CertScope): Promise<CMResult>¹⁸⁺	根据证书的位置获取用户根CA证书列表。
certificateManager	getUserTrustedCertificate(certUri: string): Promise<CMResult>	获取用户根CA证书的详细信息。
certificateManager	getCertificateStorePath(property: CertStoreProperty): string¹⁸⁺	获取证书的存储路径。

开发步骤

权限申请和声明。

使用安装和删除接口需要申请权限：ohos.permission.ACCESS_ENTERPRISE_USER_TRUSTED_CERT或ohos.permission.ACCESS_USER_TRUSTED_CERT

使用获取列表和获取详情接口需要申请权限：ohos.permission.ACCESS_CERT_MANAGER

申请流程请参考：申请应用权限

声明权限请参考：声明权限
导入相关模块。

   import { certificateManager } from '@kit.DeviceCertificateKit';

安装用户CA证书、获取用户CA证书列表、获取用户证书详情、删除用户CA证书。

   async function userCASample() {
     /* 安装的用户CA证书数据需要业务赋值。 */
     let userCAData: Uint8Array = new Uint8Array([

获取系统CA证书路径、用户CA证书路径。应用可以直接通过该路径访问CA证书。

   function getUserCAPath() {
     try {
       /* 获取系统CA的存储位置。 */
       let property1: certificateManager.CertStoreProperty = {
         certType: certificateManager.CertType.CA_CERT_SYSTEM,
       }
       let systemCAPath = certificateManager.getCertificateStorePath(property1);
       console.info(`Success to get system ca path: ${systemCAPath}`);
   
       /* 获取当前用户的用户CA存储位置。 */
       let property2: certificateManager.CertStoreProperty = {
         certType: certificateManager.CertType.CA_CERT_USER,
         certScope: certificateManager.CertScope.CURRENT_USER,
       }
       let userCACurrentPath = certificateManager.getCertificateStorePath(property2);
       console.info(`Success to get current user's user ca path: ${userCACurrentPath}`);
   
       /* 获取设备公共的用户CA存储位置。 */
       let property3: certificateManager.CertStoreProperty = {
         certType: certificateManager.CertType.CA_CERT_USER,
         certScope: certificateManager.CertScope.GLOBAL_USER,
       }
       let globalCACurrentPath = certificateManager.getCertificateStorePath(property3);
       console.info(`Success to get global user's user ca path: ${globalCACurrentPath}`);
     } catch (error) {
       console.error(`Failed to get store path. Code: ${error.code}, message: ${error.message}`);
     }
   }
