Description

English:
Certificate type identifier for Extended Validation (EV) Secure Sockets Layer / Transport Layer Security (SSL/TLS) server certificates. The strictest validation level is applied; it is used for high-trust scenarios such as finance and e-commerce.
Status: registered but unused. No certificate profile or CPS document has referenced this type identifier; when used, map it to the EV policy (1.3.6.1.4.1.59719.5.1.120) and follow the CA/Browser Forum EV Guidelines. The unused state shall be re-verified at each revision of this file.
Recommendation: EV certificates require the full validated subject information to be present; validate the subject fields at issuance time because inconsistent EV subjects may be rejected by relying parties.

Verification: 2026-10-22 — this arc and all its sub-ordinates are confirmed unused; re-verify the unused state at each revision of this file.

扩展验证（Extended Validation，EV）安全套接层/传输层安全（SSL/TLS）服务器证书的证书类型标识。采用最严格的验证等级，用于金融、电商等高可信场景。
状态：已注册但未使用。尚无证书模板或 CPS 文档引用本类型标识；使用时应映射到 EV 策略（1.3.6.1.4.1.59719.5.1.120）并遵循 CA/Browser Forum EV 规范。本文件每次修订时须重新核验该未使用状态。
建议：EV 证书要求主体信息完整且经过验证，签发时应校验主体字段一致性，因为不一致的 EV 主体可能被依赖方拒绝。
