RSA秘密鍵と自己署名証明書を使用してp12ファイルを生成する方法

以下の具体的な手順が2週間前には効果がありましたが、今はそうではないと思います。 RSA秘密鍵で始まり、rsa.pem自己署名証明書を生成します。

openssl req -new -x509 -key rsa.pem -out rsa.cer

その後、ファイルを生成しようとしますp12。

openssl pkcs12 -export -out rsa.p12 -inkey rsa.pem -in rsa.cer

ただし、次のメッセージのみが表示されます。

Usage: pkcs12 [options]
where options are
-export       output PKCS12 file
-chain        add certificate chain
-inkey file   private key if not infile
