Question

I have created self signed Certificated by using openssl and have mongodb.pem(mongodb.key + mongodb.cert) file generated from openssl. Also i have my mongodb-ssl.conf file as follows

storage:
 dbPath: C:\Users\rajshanb\MongoDB\data\db\
net:
 port: 27018 
 bindIp: 127.0.0.1
 ssl:
 Mode = requireSSL
 PEMKeyFile = C:\Users\rajshanb\mongodb.pem
 PEMKeyPassword = rajshanb
 CAFile = C:\Users\rajshanb\client.pem

But when i am trying to start the server from terminal :

C:\Users\rajshanb\MongoDB\mongodb\bin>mongod -f C:\Users\rajshanb\mongodb-ssl.conf
Unrecognized option: net.ssl
try 'mongod --help' for more information
