end to end encrypted chat with LDAP authentication

• authentication using Apache Directory Studio (LDAP)
• client generates private key and certificate signing request
• the CA (server.py) stores a signed certificate for that user
• when a client wants to send a message to another destination:
  1. first it requests the destinations certificate from the server
  2. then it encrypts the message using its public key and sends it to the server
• when a client receives an encrypted message:
  1. it decrypts it using its private key
