create a key?!

[searain]

is there a simple "create a key" script there?

i am thinking like this. get some kind int values of a string and use this value as the SEED to create a random number. this random number could be the Key.

say, if you give me "[e-mail]" the key value will alway be for example 4211

if you give me "[e-mail]" the key value will always be 3231.

so a client can send me the e-mail and i return him a key.

then he can use the name and key to access the "member only" secured section.

when he came to the secured content area, i checked the e-mail and create a key value again and i will check to see if the key matchs the key he sent to me. if match, he is in.

i am thinking using this for a member only secured content area without big security requirements. no database of passwords needed here.

thanks.

thats a good question. I think the logic is pretty clear on how to do this, it just would take a complicated algorithm to assign a string of numbers to a certain letter that is inputted. I would like to see something like this if you find it 😉

you could take the MD5 hash of the email plus some secret seed characters and pick the first 5 letters. something like

$key = substr(md5($email . "SECRET SEED"), 0, 5);
