Very nice. Nice plausible set of candidate authors also: pub 1022/5AC7B865 1992/12/01 loki@obscura.com pub 1024/2B48F6F5 1996/04/10 Ian Goldberg <iang@cs.berkeley.edu> pub 1024/97558A1D 1994/01/10 Pr0duct Cypher <alt.security.pgp> pub 1024/2719AF35 1995/05/13 Ben Laurie <ben@gonzo.ben.algroup.co.uk> pub 1024/58214C37 1992/09/08 Hal Finney <74076.1041@compuserve.com> pub 1024/C8002BD1 1997/03/04 Eric Young <eay@cryptsoft.com> pub 1024/FBBB8AB1 1994/05/07 Colin Plumb <colin@nyx.cs.du.edu> Wonder if we can figure out who is most likely author based on coding style from such a small set. It has (8 char) TABs but other wise BSD indentation style (BSD normally 4 spaces). Also someone who likes triply indirected pointers ***blah in there. Has local variables inside even *if code blocks* eg, inside main() (most people avoid that, preferring to declare variables at the top of a function, and historically I think some older gcc / gdb couldn't debug those variables if I recall). Very funky use of goto in getpgppkt, hmmm. Somewhat concise coding and variable names. Off the cuff guess based on coding without looking at samples of code to remind, probably Colin or Ian. Of course (Lance Cottrell/Ian Goldberg/Pr0duct Cypher/Ben Laurie/Hal Finney/Eric Young/Colin Plumb) possibly deviated or mimicked one of their coding styles. Kind of interesting to see a true nym in there also. Also the Cc -- Coderpunks lives? I think the Cc coderpunks might be a clue also, I think some of these people would know it died. I think that points more at Colin. Other potential avenue might be implementation mistake leading to failure of the scheme to robustly make undecidable which of the set is the true author, given alpha code.

This program can be used by anonymous contributors to release partial information about their identity - they can show that they are someone from a list of PGP key holders, without revealing which member of the list they are. Maybe it can help in the recent controvery over the identity of anonymous posters. It's a fairly low-level program that should be wrapped in a nicer UI. I'll send a couple of perl scripts later that make it easier to use.
