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

  1. 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

  2. 导入相关模块。

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

  3. 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([

    0xE6, 0x25,
  ]);

  let certUri: string = '';
  let certScope = certificateManager.CertScope.CURRENT_USER;
  try {
    /* 在当前用户下，安装用户CA证书。 */
    let result = certificateManager.installUserTrustedCertificateSync(userCAData, certScope);
    certUri = (result.uri != undefined) ? result.uri : '';
    console.info(`Succeeded in install user ca cert, certUri is ${certUri}`);
  } catch (err) {
    console.error(`Failed to install user ca cert. Code: ${err.code}, message: ${err.message}`);
  }

  try {
    /* 获取用户CA证书详情。 */
    let result = await certificateManager.getUserTrustedCertificate(certUri);
    if (result === undefined || result.certInfo == undefined) {
      console.error('The result of getting user ca cert is undefined.');
    } else {
      let certInfo = result.certInfo;
      console.info('Succeeded in getting user ca cert.');
    }
  } catch (err) {
    console.error(`Failed to get user ca certificate. Code: ${err.code}, message: ${err.message}`);
  }

  try {
    /* 获取当前用户下的用户CA证书列表。 */
    let result = await certificateManager.getAllUserTrustedCertificates(certScope);
    if (result == undefined) { /* 用户根CA证书个数为0时，返回result为undefined。 */
      console.info('the count of the user trusted certificates is 0');
    } else if (result.certList == undefined) {
      console.error('The result of getting current user trusted certificates is undefined.');
    } else {
      let list = result.certList;
      console.info('Succeeded in getting user ca cert list.');
    }
  } catch (err) {
    console.error(`Failed to get user ca certificate. Code: ${err.code}, message: ${err.message}`);
  }

  try {
    /* 删除安装的用户CA证书。 */
    certificateManager.uninstallUserTrustedCertificateSync(certUri);
  } catch (err) {
    console.error(`Failed to uninstall user ca certificate. Code: ${err.code}, message: ${err.message}`);
  }
}

  4. 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}`);
  }
}
