 dir-spec.txt says
 {{{
    "extra-info-digest" digest NL

        [At most once]

        "Digest" is a hex-encoded digest (using upper-case characters) of
 the
        router's extra-info document, as signed in the router's extra-info
        (that is, not including the signature).  (If this field is absent,
 the
        router is not uploading a corresponding extra-info document.)
 }}}

 But the reality is that these lines look like
 {{{
 extra-info-digest 9A0DC5BE9F00423F1929B10E9FEF7942481215AB
 HjMoC57FJUUXJ7Gwv/ouFb+otnZIfxu9cj1sh6Nd618
 }}}

 It looks like that second digest is a sha256, and it is related to the
 introduction of the extra_info_digest256 element in routerinfo_t.

 I'm guessing the fix is to update the spec -- and maybe figure out what
 went wrong in the earlier proposal and ticket process that updating the
 spec got skipped. :)
