Hi,

> - Incorporated RFC 6637 (ECDSA and ECDH, using NIST curves)

  # Security Considerations

  A compliant application MUST only use iterated and salted S2K to
  protect private keys, as defined in {{iterated-and-salted-s2k}},
  "Iterated and Salted S2K".

This precludes the use of private S2K algorithms (algos 100 to 110).

  https://tools.ietf.org/html/rfc4880#section-3.7

Would a MUST NOT use Simple S2K and MUST NOT use Salted S2K be better?

:) Neal
