使用OpenSSL C安全的客戶端/服務器程序

我想用C語言編寫安全的客戶端/服務器程序與OpenSSL。我發現了一個代碼示例在http://www.rtfm.com/openssl-examples/但我得到這個錯誤：服務器：SSL閱讀問題客戶端：證書不驗證使用OpenSSL C安全的客戶端/服務器程序

我認爲這個問題是與證書的產生，但我不能找到它。

有什麼想法？

感謝

我下載的例子，驗證了錯誤：

「10 X509_V_ERR_CERT_HAS_EXPIRED：證書已過期」

使用這個命令：

openssl x509 -in client.pem -noout -text

我得到這樣的輸出：
