ssl:certificate:self-signed:create
Generate a self-signed SSL certificate
$ openssl req -x509 -newkey rsa:4096 -keyout ${key_file} -out ${cert_file} -sha256 -days ${expiration_days}
try on your machine
This command is used to generate a self-signed X.509 certificate using OpenSSL.
Here's a breakdown of the command and its options:
openssl req
: Invokes the OpenSSL command-line tool for certificate requests and certificate generation.-x509
: Specifies that an X.509 certificate should be created instead of a certificate signing request (CSR).-newkey rsa:4096
: Generates a new RSA private key with a bit length of 4096.-keyout ${key_file}
: Specifies the output file for the generated private key. The${key_file}
is a placeholder that should be replaced with the actual filename and path.-out ${cert_file}
: Specifies the output file for the generated X.509 certificate. The${cert_file}
is a placeholder that should be replaced with the actual filename and path.-sha256
: Specifies the message digest algorithm (SHA-256) to be used for the certificate.-days ${expiration_days}
: Specifies the validity period (in days) for the generated certificate. The${expiration_days}
is a placeholder that should be replaced with the desired number of days.
By executing this command with the appropriate values provided for ${key_file}
, ${cert_file}
, and ${expiration_days}
, you will generate a new RSA private key and a corresponding X.509 certificate with the specified configuration.
