I'm creating a certificate using this command:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout localhost.key -out localhost.crt -config localhost.conf

with this config:

[req]
default_bits       = 2048
default_keyfile    = localhost.key
distinguished_name = req_distinguished_name
req_extensions     = req_ext
x509_extensions    = v3_ca

[req_distinguished_name]
commonName                  = Common Name (e.g. server FQDN or YOUR name)
commonName_default          = localhost
commonName_max              = 64


[req_ext]
subjectAltName = @alt_names


[v3_ca]
subjectAltName = @alt_names
basicConstraints = critical, CA:false
keyUsage = keyCertSign, cRLSign, digitalSignature,keyEncipherment


[alt_names]
DNS.1   = localhost

But the command asks for a Common name and password, How can I send them as the parameter to openssl. I tried other solutions but none of them worked.

You can use -subj on the command line to pass the certificate's Subject.

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout localhost.key -out localhost.crt -config localhost.conf -subj "/O=My Org/OU=My Dept/CN=My Service"
