In this article you’ll find how to generate CSR (Certificate Signing Request) using OpenSSL from the Linux command line, without being prompted for values which go in the certificate’s subject field. $ openssl req -new-key (1 で作成したキーファイル)-out (出力したいCSRファイル名) コマンドを実行するとプロンプトが表示されてサーバー識別名(DN)情報の入力を求められるので、求められるがままに入力する。 入力する項目は … $ openssl req -new -key private.key-out domain.example.com.csr You are about to be asked to enter information that will be incorporated into your certificate request. openssl req -new -sha256 -key store.scriptech.io.key.pem -config /etc/ssl/openssl.cnf -out store.scriptech.io.csr Verify the CSR To view the contents of your new CSR, use the following command: openssl req -text -noout -verify -in On startup, the openssl req command reads the [ req ] section of openssl.cnf for default values that are not specified as arguments or options to the req command. To generate a self-signed SSL certificate in a single openssl command, run the following in your terminal. Create a new private key using OpenSSL with 2048-bit strength and encrypted using des3: openssl> genrsa -des3 -out c:\ssl\keys\mcafee.key 2048 Generate the Certificate Signing Request (CSR) file: openssl> req -new As of OpenSSL 1.1.1, providing subjectAltName directly on command line becomes much easier, with the introduction of the -addext flag to openssl req (via this commit). Requirement: OpenSSL platform to execute the following single line command to generate a self-signed certificate. openssl req -out geekflare.csr -newkey rsa:2048 -nodes -keyout geekflare.key The above command will generate CSR and a 2048-bit RSA key file.
