证书PKCS7签名

PKCS#7是用于存储签名或加密数据的标准语法。CMS作为PKCS#7的扩展，支持的数据类型包括数据、签名数据、信封数据、签名和信封数据、摘要数据以及加密数据。该标准常用于保护数据的完整性和机密性。目前仅支持PKCS7签名数据。

开发步骤

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

调用cert.createCmsGenerator创建cmsGenerator对象。
调用cmsGenerator.addSigner添加签名者信息。
调用cmsGenerator.addCert添加证书。
调用cmsGenerator.doFinal获取Cms最终签名数据。

异步方法示例：

import { cert } from '@kit.DeviceCertificateKit';
import { BusinessError } from '@kit.BasicServicesKit';
