  The invention of a large-scale quantum computer would pose a serious
  challenge for the cryptographic algorithms that are widely deployed
  today.  The Cryptographic Message Syntax (CMS) supports key transport
  and key agreement algorithms that could be broken by the invention of
  such a quantum computer.  By storing communications that are
  protected with the CMS today, someone could decrypt them in the
  future when a large-scale quantum computer becomes available.  Once
  quantum-secure key management algorithms are available, the CMS will
  be extended to support them, if current syntax the does not
  accommodated them.  In the near-term, this document describes a
  mechanism to protect today's communication from the future invention
  of a large-scale quantum computer by mixing the output of key
  transport and key agreement algorithms with a pre-shared key.
