Certification Authority

CA即Certification Authority,是一些值得信赖的组织。他们负责颁发个人或者团体的公钥。这些个人或团体被称为subject of that certificate。

发布的certificate中包括:公钥/私钥对中的公钥。

Hash的校验可以保证数据的完整性,数据是否被篡改依赖于数字认证。

 

A digital certificate is a credential issued by a trusted organization or entity called a certification authority (CA). This credential contains a public key (see Public/Private Key Pairs) and data that identifies the certificate's subject. A certificate is issued by a CA only after the CA has verified the certificate subject's identity and has confirmed that the public key included with the certificate belongs to that subject.

数字证书包括解密用的公钥,同时还有一个CA用私钥处理过的签字,来保证这个公钥是属于某公司或某团体的。这样可以证明证书是由CA颁发的。
