openssl req

OpenSSL command to manage PKCS#10 Certificate Signing Requests. More information: https://www.openssl.org/docs/manmaster/man1/openssl-req.html.

  • Generate a certificate signing request to be sent to a certificate authority:

openssl req -new -sha256 -key {{filename.key}} -out {{filename.csr}}

  • Generate a self-signed certificate and a corresponding keypair, storing both in a file:

openssl req -new -x509 -newkey {{rsa}}:{{4096}} -keyout {{filename.key}} -out {{filename.cert}} -subj "{{/C=XX/CN=foobar}}" -days {{365}}
