hi friends
I need a hash function to build a Unique serial number by mixing a request
code and a user name
request codes are strings like this: They are literally HEX codes of MAC mac
addresses.
"002314EFD000544AB05345300045675609782123C3254B312123D12312EE13123F123D123123E00000000E00000000E0000000E0000000E0000000E00000000E00000000"
i want to create a function that mix together this request code with user
name that user entered and create new serial number.
What implications i have to satisfy to create such hash function in php?
Thanks for any suggestion
