openssl 1.1.0f 生成中文证书乱码的解决方案

1. openssl req 命令

openssl req -utf8 -new -config client/req.cnf -key client/client-key.pem -sha1 -out client/client-req.csr 

修改方法: 添加参数 -utf8

2. openssl x509 命令

openssl x509 -req -in client/client-req.csr -out client/client-cert.pem-extfile client/x509.cnf -sha1 -CA ca/ca-cert.pem -CAkey ca/ca-key.pem -CAcreateserial -days 365

修改方法: 修改源码文件 asn1_gen.c 

static ASN1_TYPE *generate_v3(const char *str, X509V3_CTX *cnf, int depth,int *perr);

118行: asn1_tags.format =ASN1_GEN_FORMAT_ASCII;  改为 asn1_tags.format =ASN1_GEN_FORMAT_UTF8

另外: client/req.cnf 和 client/x509.cnf 这2个配置文件保存为 utf8 编码
