openssl req
命令在 MinGW 环境下无法正确生成证书的 Bug。
以下面的命令为例
1openssl req -new -newkey rsa:2048 -sha256 -nodes \
2 -out sample.com.csr \
3 -keyout sample.com.key \
4 -subj "/C=CountryShortName/ST=ProvinceName/L=CityName/O=Example Inc./OU=Web Security/CN=sample.com"
执行后报错
1Generating a 2048 bit RSA private key
2...............................................................................+++
3................................................................................................................+++
4writing new private key to 'sample.com.key'
5-----
6Subject does not start with '/'.
7problems making Certificate Request
问题出在 MingW 身上,需要在 -subj 的参数前面加一个斜杠 /
:
1openssl req -new -newkey rsa:2048 -sha256 -nodes \
2 -out sample.com.csr \
3 -keyout sample.com.key \
4 -subj "//C=CountryShortName/ST=ProvinceName/L=CityName/O=Example Inc./OU=Web Security/CN=sample.com"
但是第一个 /
使得后面的 /
被认为是 NID 的一部分,这又会导致第一段主题信息被视为
/C=CountryShortName
而不是 C=CountryShortName
。
结果得到下面的错误:
1Generating a 2048 bit RSA private key
2.+++
3................................................................................................................................................+++
4writing new private key to 'sample.com.key'
5-----
6Subject Attribute /C has no known NID, skipped
为了解决这个问题,可以在 /C=CountryShortName
,前面再加一段 /skip=yes
。
1openssl req -new -newkey rsa:2048 -sha256 -nodes \
2 -out sample.com.csr \
3 -keyout sample.com.key \
4 -subj "//skip=yes/C=CountryShortName/ST=ProvinceName/L=CityName/O=Example Inc./OU=Web Security/CN=sample.com"
就保护了 C=CountryShortName
不被影响。
