I am using PGPTools to handle all the crypto functions in the second generation remailer that I have written. All the copies of PGPTools that I have found seem to be set up to compile on SUN workstations only.

That's interesting, because I developed it under Linux and MS/DOS, and there was a lot of trouble at the beginning with it not running on big-endian machines. It sounds like whoever "fixed" it for sparcs broke it for little-endian machines. The original should still be on ftp.csn.net; get it there and it should work.

Mixmaster is both a remailer and a front end, and therefor must run on many different platforms. I have been able to compile PGPTools on Linux and FreeBSD, but PGPTools produces invalid RSA blocks. If you (or anyone else reading this) have ported PGPTools to other platforms could you send me the source and makefile, or point me to them. If not, could you help me do it, the source code is a tangle, and it will take me a long time to do on my own (I am a brute force programer, not a C wizard).

Get the original, test it, and post the results.

Ok, I grabbed second oldest version (this included a bugfix). I compiles and seems to work fine when I use it with PTD. It fails when run under Mixmaster. The failure is deep inside pgptools. When I call pgpk_findkey to get a key from a public key ring (by name not number), it chugs along checking each key id in the ring. Each time it checks a key, it uses a pair of fifo's which it then destroys. After checking the second id, when it is destroying kc (k is destroyed without problems both times), I get a segmentation violation in the line nfb=fb->next; Since kc was simply a copy of k kc=fifo_copy(k); I suspect the problem lies in fifo_copy. These are all mem fifo's. If you want to look at the source code I am playing with (with tons of debugging printfs in it) let me know and I will stick it on my ftp. -----BEGIN PGP SIGNATURE----- Version: 2.6 iQCVAwUBLuOBVFVkk3dax7hlAQGYNAP9GvDMvdSKA1vUsmJB/xitPVsiazNeZjXJ NrjwouMg85VR1ri1rm1y2NuKbHEljGfwNB7z8euy7e1clptRsN4WWrP+ASSfrire 9Clan80Ep4lEA+83caArQv3Hcdb8+8FnLpXd/zrPI2V/3TVM2OrfU7/RtUo+3Pr3 JE2d0s6Jn+E= =jlbs -----END PGP SIGNATURE----- -- Lance Cottrell <lcottrell@popmail.ucsd.edu> http://nately.ucsd.edu/~loki/ Home of the remailer chaining script "chain".
