I'm attempting to create a config file in Ubuntu to create a self-signed certificate, but when I attempt to create the certificate key I'm getting the following error:
Here's the actual config in the vim editor, where you can see it does have a distinguished name, so I suspect the real error is whatever is wrong with line 1 - but as you see line one just a comment?
Your [ req ] section appears to be missing the distinguished_name part. EDIT: I see you have it, it's just pointing a wrong or non-existent section. See below for what I have in my own config file, which works.
[ req ] # Options for the `req` tool (`man req`). default_bits = 4096 distinguished_name = req_distinguished_name string_mask = utf8only # SHA-1 is deprecated, so use SHA-2 instead. default_md = sha256 # Extension to add when the -x509 option is used. x509_extensions = v3_ca [ req_distinguished_name ] # See <https://en.wikipedia.org/wiki/Certificate_signing_request>. # See <https://en.wikipedia.org/wiki/Certificate_signing_request>. countryName = Country Name (2 letter code) stateOrProvinceName = State or Province Name localityName = Locality Name 0.organizationName = Organization Name organizationalUnitName = Organizational Unit Name commonName = Common Name emailAddress = Email Address Based on what you have, I believe you'll need to insert the following into your [ req ] section:
distinguished_name = root_ca_distinguished_name
