How could a hacker exploit a cookie encrypted with 64 bit encryption?
I suppose the entire cookie is encrypted so a hacker could run that cookie through his decryption program until I starts finding patterns which match the English language. Is this how a hacker would crack it?
Or are there key terms the software would be looking for?
How long could this process take and wouldn't he need a pretty high powered machine for that?
Conversely, what is the highest number of bits as the best practices alternative? And how long would it take that same PC to crack it?
