How does PrivateXMS work?
Before you can start using PrivateXMS, the software must be installed on both phones followed by a pairing process. On sending your first XMS message to another person, a pairing process under the option called “PairMe” will take place. This is normal for PKI based encryption technology. In essence, when you install XMS on your phone, two keys are generated. One key is kept secret on you phone and is called the Private key. Another key is sent out to other people and is called the Public Key. Only the Public Key can encrypt / decrypt messages by the Private Key. Thus, if you have somebody else’s public key, you can send a message that only they can decrypt with their private key. This is why you have to ‘pair up’ via PrivateXMS’s PairMe function before sending any PrivateXMS messages. Each contact only need to be paired once.
