### validate

validate(certChain : CertChainData, callback : AsyncCallback\<void>) : void

表示校验X509证书链，使用Callback回调异步返回结果。
由于端侧系统时间不可信，证书链校验不包含对证书有效时间的校验。如果需要检查证书的时间有效性，可使用X509证书的[checkValidityWithDate](#checkvaliditywithdate)方法进行检查。详见[证书规格](../../security/DeviceCertificateKit/certificate-framework-overview.md#证书规格)。
