CRYPT-CR

  Server: uniq, salt
  Client: SHA256(uniq ":" crypt(salt, passwd)) XOR passwd

SETTING UP DNS

  You need a record like this in your DNS server configuration:

    _xmpp-server._tcp IN SRV 0 10 5222 xmpp

  xmpp is the hostname of the server the vink daemon is running on.  If your
  domain is "example.org", this would mean "host.example.org" handles the
  "user@example.org" addresses.

SETTING UP TLS

  A TLS server needs a private key and a certificate that verifies the owner
  of this private key.  The certificate is usually provided by a Certificate
  Authority (CA).

  To create the private key, run:

    openssl genrsa -out /etc/vink.d/privkey.pem

  To create a certificate signing request for this key, run:

    openssl req -key /etc/vink.d/privkey.pem -new -out key.csr

  The "Common Name" certificate parameter is what software will look at to
  verify host names.  If your server is hosting "user@example.org", you need to
  enter "example.org" as your Common Name.

  Now you submit the "key.csr" file to a Certificate Authority, and you will
  get a certificate chain in return.  Save that file as
  "/etc/vink.d/certiciates.pem".  The reason why we call it a chain, is that
  there may be a series of certificates verifying each other, before ultimately
  ending up with a signature from someone trusted by all the major operating
  systems.

  You do not need the certificate from a Certificate Authority if you're only
  doing testing, or running on a closed network.  To sign your own certiicate,
  run this command instead of the second command:

    openssl req -key /etc/vink.d/privkey.pem -new -x509 -out /etc/vink.d/certificates.pem

SSL test:

  openssl s_client -CAfile /etc/ssl/certs/ca-certificates.crt -host wave.rashbox.org -port 5222
