Openssl用途无效

当Openssl生成无效的\u时，会查看哪些证书字段

我正在使用OpenSSL生成证书

---

首先生成主证书，然后生成客户端证书。现在，当我尝试连接服务器时，它会生成无效的目的

有一个扩展名

keyausage

，它指定了可以对证书执行的操作。请注意，某些程序未使用此字段

从X509文档：

X509_V_ERR_INVALID_PURPOSE: unsupported certificate purpose
    the supplied certificate cannot be used for the specified purpose.

手册页列出了参数和另一个名为

extendedKeyUsage

的参数的可能值：

Key Usage.
    Key usage is a multi valued extension consisting of a list of names of
    the permitted key usages.

    The supporte names are: digitalSignature, nonRepudiation,
    keyEncipherment, dataEncipherment, keyAgreement, keyCertSign, cRLSign,
    encipherOnly and decipherOnly.

    Examples:
     keyUsage=digitalSignature, nonRepudiation
     keyUsage=critical, keyCertSign 

Extended Key Usage.
    This extensions consists of a list of usages indicating purposes for
    which the certificate public key can be used for,

    These can either be object short names of the dotted numerical form of
    OIDs.  While any OID can be used only certain values make sense. In
    particular the following PKIX, NS and MS values are meaningful:

     Value                  Meaning
     -----                  -------
     serverAuth             SSL/TLS Web Server Authentication.
     clientAuth             SSL/TLS Web Client Authentication.
     codeSigning            Code signing.
     emailProtection        E-mail Protection (S/MIME).

     msCodeInd              Microsoft Individual Code Signing (authenticode)
     msCodeCom              Microsoft Commercial Code Signing (authenticode)
     msCTLSign              Microsoft Trust List Signing
     msSGC                  Microsoft Server Gated Crypto
     msEFS                  Microsoft Encrypted File System
     nsSGC                  Netscape Server Gated Crypto

    Examples:
     extendedKeyUsage=critical,codeSigning,1.2.3.4
     extendedKeyUsage=nsSGC,msSGC

在螺母和螺栓级别，您使用的openssl.cnf值可能还有其他用途，比如电子邮件。这就是为什么它们对于您尝试建立的服务器连接无效

检查您的openssl.cnf内容，并查看openssl源中提供的示例，以了解可能与连接到传统web浏览器的stock TLS web服务器一起工作的内容。
