openssl pem ファイルから証明書部分だけを取得する
OpenSSL を使用しないでください。代わりに、、、およびリダイレクトを使用cat
しawk
てsed
ください。
例えば:
$ ls *.pem
DigiCertHighAssuranceEVRootCA.pem
$ cat DigiCertHighAssuranceEVRootCA.pem
-----BEGIN CERTIFICATE-----

次に、最初の行を叩きます。
$ cat DigiCertHighAssuranceEVRootCA.pem | sed '1,1d'

...
そして最後の行を叩きます:
$ cat DigiCertHighAssuranceEVRootCA.pem | sed '$ d'
...

それらをまとめる:
$ cat DigiCertHighAssuranceEVRootCA.pem | sed '1,1d' | sed '$ d'

最後に、sed
セミコロンで個別のコマンドを分離することにより、コマンドを折りたたむことができます。

さて、あなたが何をしようとしていたのかわからない-certopt X
ので、これを一粒の塩で取ってください... 証明書を読み取り可能な形式で印刷するには、次を使用します-text -noout
。

OpenSSL を使用してエンコードされた証明書だけを出力する方法はありますか? それはどのように行われますか?
いいえ。OpenSSL に-outform
は-inform
. DER、PEM、NET の 3 つのインフォームとアウトフォームが利用可能です。それらのどれも裸の Base64 ではありません。
