Subject: RACF format
Dhiru -
racf_fmt_plug.c needs a proper valid(), not just a check for $racf$.
Also, it could benefit from a prepare() - to extract the username.
Right now, the required input format is:
userid:$racf$*userid*deshash
whereas with prepare() you could make it simply:
username:$RACF$hash
and have that converted by prepare() to the representation that embeds
the username internally (for storage in john.pot).
BTW, I see no reason to have a "*" before the username. Your code could
instead assume that the username starts right after $RACF$ (of course,
if this is the encoding that you'd choose to use).
Thanks,
Alexander
