提取從OpenSSL的密鑰文件的公鑰和私鑰

-1

openssl gendsa -out myDSAkey.pem sharedDSA.pem

然後，我可以「提取」我的私人和公共密鑰使用以下命令：

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

當我執行下列操作之一：

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

，我感到我從SYSTE需要的所有信息L：

這是奇怪的，因爲我認爲在文件myDSApriv.pem我提取myDSAkey.pem與私鑰相關內容。更令人驚訝的是，我沒有myDSApub.pem的這些信息。執行命令：

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

只給

，而我想它給前給出的十六進制格式。

有沒有辦法顯示myDSApriv.pem和myDSApub.pem上的十六進制信息，而不是別的？爲什麼myDSApriv.pem包含有關所有參數的信息？

Stack Overflow是編程和開發問題的網站。這個問題似乎與題目無關，因爲它不涉及編程或開發。請參閱幫助中心的[我可以詢問哪些主題]（http://stackoverflow.com/help/on-topic）。也許[超級用戶]（http://superuser.com/），[Unix＆Linux堆棧交換]（http://unix.stackexchange.com/）或[信息安全堆棧交換]（http：//security.stackexchange .com /）將是一個更好的地方問。 – jww

打印公鑰時，您沒有使用-text標誌，因此它沒有以人類可讀的形式打印它。您可以進一步添加-noout以避免在最後打印PEM編碼密鑰。

此外，請注意，您已將此私鑰發佈到Internet，因此請確保在執行任何您關心的任何事情之前生成新的密鑰對。
