[comp.sys.ibm.pc] Password algorithm

ray@philmtl.philips.ca (Ray Dunn) (02/13/90)

I have a need to provide a password mechanism in a particular situation,
but, for various boring reasons, have only got a couple of spare bytes in
which to store it.

My first approach would be to compute a CRC on the password, and only store
that.

Can someone point me to the best source of ideas on this subject,
particularly on how to compute the number of different passwords, say 8
characters long, which will match a given CRC value computed by various
algorithms?

Anyone have any other bright ideas?  Please accept the lack of space to
store the full password as a given.

If you email me your response I will summarize back to this newsgroup.

Thanks in advance for your assistance.
