VerifiedSSL/TLS certificates establish secure channels through asymmetric encryption technology and are issued by trusted CAs (Certificate Authorities).76% similarUnverifiedCertificate pinning can defend against man-in-the-middle attacks: even if an attacker holds a valid certificate issued by a trusted CA, the connection is still rejected as long as the public key hash does not match the pinned value.75% similarUnverifiedA rejection mechanism based on public key hashes is more precise than one based on CA names or root certificates, because the same CA may issue certificates with multiple different public keys, and attackers may also abuse certificates through cross-signing and other means.74% similarUnverified中间人代理通过向系统证书库注入自定义根CA证书，使代理签发的伪造证书被客户端接受，从而实现SSL/TLS解密74% similarUnverifiedThe security of the CA trust system depends on its weakest CA — if any CA is compromised or has validation flaws, it may result in legitimate certificates being issued for domains not owned by the requester.71% similar
