Might I suggest the standard 'message digest' algorithm, md5, described =
in
rfc1321? An md5 header line is even (officially) part of HTTP, although =
I
haven't seen too many servers that return it. . . yet. There's a =
standard C
implementation, and Neil Winton even put together a Perl implementation. =
See
<http://www.gl.umbc.edu/~mabzug1/md5/md5.html> for (marginally) more
information.
I agree totally. This was actually the crypto algorithm I was thinking =
of but couldn't think of the name. The fact that HTTP already specifies =
it's use (which I didn't know) doesn't really leave any other logical =
alternative.
Guess this means I've got more work to do now :-(
Thanks,
David
