seems to be just ciphers that the hifn handle who have the trouble.
received a suggestion that it might be whenever the hifn is being
used by >1 things at once; tried a test involving setting
'-o MACs=blahblah' or '-c blahblah' on the commandline. verified
with -v that the stuff actually was doing what i told it to.
changing the MACs= didn't affect the results.
hmac-{md5,sha1}{,-96} and hmac-ripemd160 all give corrupt MAC on input
if i am using a cipher of either aes{128,192,256}-cbc or 3des-cbc.
the arcfour jobs, blowfish, and the aes*-ctr ones (who don't use hifn)
never exhibit the issue regardless of using hmac-{md5,sha1}.
so for now, yeah, the '-c blowfish-cbc', is keeping this problem at
a lower priority than all the other problems i'm working on <BG>
