CSR:

$ openssl req -new -key fd.key -out fd.csr
... (use . for the empty fields instead of the default values)

After CSR is generated, it can be used for
- sign our own certificate
- send it to the public CA asking to sign a certificate

befre that, it's good to view/check the CSR:

$ openssl req -text -in fd.csr -noout

to renew a CSR from the existing cert, use:

$ openssl x509 -x509toreq -in fd.crt -out fd.csr -signkey fd.key

We can also use a cnf-config for automating a CSR-generation:

$ openssl req -new -config fd.cnf -key fd.key -out fd.csr
