Interesting note in current issue of PC Magazine about how DOS 4 and later generates volume ID numbers. Neil Rubenking describes a time/date hash of the form:
month plus seconds
day plus hundredths of seconds
high byte of the year plus hours
low byte of the year plus minutes
I've actually been thinking about such a time/date hash during idle brain cycles. Any thoughts on how secure such a hash is, as in how collision proof if the input date is from today forward 50 years?
thanks,
