OK Sir

can you tell me did you create your certificates on windows?
or on linux machine?

openssl req -x509 -config openssl.cnf -newkey rsa:2048 -days 365 \
     -out cacert.pem -outform PEM -subj /CN=MyTestCA/ -nodes

i executed above as
openssl req -x509 -config openssl.cnf -newkey rsa:2048 -days 365 -out cacert.pem -outform PEM -subj /CN=MyTestCA/ -nodes

because as you told me that i need to do it similarly as in the website i skipped the '\' since it wasn't a valid element in openssl.

does that caused the error?

Thanks and Regards,
Abhijit
