This is annoying to start the apache webserver with SSL. After hours of research, I found the following procedures can create a certificate that does not require to type passphrase.
It could be less secured – so use it at your own risk!!
This is how we can generate a DSA Certificate without a passphrase.
openssl dsaparam 1024 -out dsaparams
openssl gendsa -out ca.key dsaparams
openssl req -new -key ca.key -out ca.csr
openssl x509 -req -days 365 -in ca.csr -signkey ca.key -out ca.crt
