Question

我使用以下命令生成一对dsa键：

openssl gendsa -out myDSAkey.pem sharedDSA.pem

然后，我可以＆＃34;提取＆＃34;我的私钥和公钥以及命令：

openssl dsa -in myDSAkey.pem -aes128 -out myDSApriv.pem
openssl dsa -in myDSAkey.pem -out myDSApub.pem -outform PEM -pubout

执行以下任一操作时：

openssl dsa -text -inform PEM -in myDSAkey.pem
openssl dsa -text -inform PEM -in myDSApriv.pem

我从系统中获取了所需的所有信息：

这很奇怪，因为我认为在myDSApriv.pem文件中我提取了与私钥相关的myDSAkey.pem的内容。更令人惊讶的是，我没有myDSApub.pem的这些信息。执行命令：

openssl dsa -inform PEM -pubin -in nombreDSApub.pem

仅提供

虽然我希望它能给出之前给出的十六进制格式。

有没有办法在myDSApriv.pem和myDSApub.pem上显示十六进制信息而没有别的？为什么myDSApriv.pem包含有关所有参数的信息？

Answer 1

打印公钥时没有使用-text标志，因此它不会以人类可读的形式打印出来。您可以进一步添加-noout以避免在最后打印PEM编码的密钥。

另外，请注意您已将此私钥发布到Internet，因此请确保在执行任何您关心的操作之前生成新的密钥对：）。

从openssl密钥文件中提取公钥和私钥
