jabber:x:encrypted
You can use the relatively new jabber:x:encrypted namespace to
implement message-level security. It allows the attachment of
encrypted data Public Key Infrastructure (PKI) techniques, meaning
that the data is encrypted using the message sender’s private key
and decrypted by the recipient using the sender’s public key.
