The documentation for CERT_NONE, CERT_OPTIONAL, and CERT_REQUIRED were misleading and partly wrong. It fails to explain that OpenSSL behaves differently in client and server mode. Also OpenSSL does validate the cert chain everytime. With SSL_VERIFY_NONE a validation error is not fatal in client mode and does not request a client cert in server mode. Also discourage people from using CERT_OPTIONAL in client mode. (cherry picked from commit ef24b6c) Co-authored-by: Christian Heimes <[email protected]>
