}I am looking at the "crypt(3X)" routines "setkey()" and "encrypt()",
}in SysV Rel 3.2, and it's not clear to me how they're supposed to be
}used. The manual page says:
}
I have already received a VERY helpful reply to this from
Mike Oliver at Pyramid, so no need for more follow-ups.
Briefly, the 64 character arrays passed to setkey() and
encrypt() are "encoded" versions of the binary representations
of the characters; for example, if the first character is
'A', then 'A' = 0x41 = 01000001 which leads to:
setargs[0] = 0
setargs[1] = 1
setargs[2] = 0
and so on... based on the manual page, I hadn't figured this
part of it out, and didn't understand what was supposed to
go into the argument arrays to setkey() and encrypt().
