What’s the Difference Between DV, OV, IV, and EV Certificates?
DV，OV，IV和EV证书之间有什么区别？
Although all X.509 certificates use similar methods to assure encryption, authentication, and integrity, they vary significantly in the information they include about the identities that they secure. A useful way to categorize certificates is by the method used by the certificate authority (CA) to validate the subject information included in the certificate: Domain Validation (DV) is the lowest level of validation, and verifies that whoever requests the certificate controls the domain that it protects. Organization Validation (OV) verifies the identity of the organization (e.g. a business, nonprofit, or government organization) of the certificate applicant. Individual Validation (IV) verifies the identity of the individual person requesting the certificate. Extended Validation (EV), like OV, verifies the identity of an organization. However, EV represents a higher standard of trust than OV and requires more rigorous validation checks to meet the requirements set by the CA/Browser Forum.
虽然所有 X.509证书 使用类似的方法来确保加密，身份验证和完整性，但是它们所包含的有关所保护身份的信息差异很大。 证书分类的一种有用方法是通过证书颁发机构（CA）用来验证证书中包含的主题信息的方法： 域验证（DV） 是最低的验证级别，并验证请求证书的人员控制其保护的域。 组织验证（OV） 验证证书申请者的组织（例如，企业，非营利组织或政府组织）的身份。 个人验证（IV） 验证请求证书的个人的身份。 扩展验证（EV）与 OV 一样，验证组织的身份。 但是，EV 代表了比 OV 更高的信任标准，并且需要更严格的验证检查才能满足 CA/浏览器论坛设定的要求。
