1.验证域名、有效期等信息是否正确。证书上都有包含这些信息,比较容易完成验证;

2.判断证书来源是否合法。每份签发证书都可以根据验证链查找到对应的根证书,操作系统、浏览器会在本地存储权威机构的根证书,利用本地根证书可以对对应机构签发证书完成来源验证;

3.判断证书是否被篡改。需要与 CA 服务器进行校验;

4.判断证书是否已吊销。通过CRL(Certificate Revocation List 证书注销列表)和 OCSP(Online Certificate Status Protocol 在线证书状态协议)实现,其中 OCSP 可用于第3步中以减少与 CA 服务器的交互,提高验证效率
