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 suggestionHow about using sha1 to hash your string. If the data is unique then the hash will be unique as well. $string = $request_code.$user_name; $hash = sha1($string); -- John Jeder hat soviel Recht, wie er Macht hat. [Spinoza]
