    Also support key exchange based on public keys. See RFC 4357 for
    details of VKO key exchange algorithm. These algorithms use
    256 bit private keys. Public keys are 1024 bit for 94 and 512 bit for
    2001 (which is elliptic-curve based). Key exchange algorithms
    (VKO R 34.10) are supported on these keys too.
