Apache https certificate generation

The concept: cer == == public key certificate private key ==; pem == cer + key

The steps of:
generating different types of keys:

• 1. Generate RSA private key (unencrypted)

openssl genrsa -out rsa_private.key 2048

• 2. Generate the RSA public key

openssl rsa -in rsa_private.key -pubout -out rsa_public.key

• 3. Generate RSA private key (encrypted using aes256)

openssl genrsa -aes256 -passout pass:111111 -out rsa_aes_private.key 2048

Generate a self-signed certificate:

openssl req -new -x509 -days 3650 -key rsa_private.key -out cert.crt -config ..\conf\openssl.cnf
