证书集合及证书吊销列表集合对象的创建和获取

从输入的证书集合和证书吊销列表集合中选择满足条件的证书或者证书吊销列表。

开发步骤

1. 导入证书算法库框架模块。

   import certFramework from '@ohos.security.cert';
   

2. 基于已有的证书数据，调用cryptoCert.createX509Cert创建X509证书的对象。

3. 基于已有的CRL数据，调用cryptoCert.createX509CRL创建X509证书吊销列表的对象。

4. 调用cryptoCert.createCertCRLCollection创建CertCRLCollection的对象，并返回相应的结果。

5. 调用CertCRLCollection.selectCerts查找所有与X509CertMatchParameters匹配的证书对象数组，并返回结果。

6. 调用CertCRLCollection.selectCRLs查找所有与X509CRLMatchParameters匹配的证书吊销列表数组，并返回结果。

import util from '@ohos.util';
