MD5, a hash encrytion of texts. although it is supposed to be uncovertable it can be converted back recently. it is a very easy function to use but uesed a lot in sending encrypted data and storing it, like this forum it uses it to store passwords. this is how it works:
this will ouput 1e2db57dd6527ad4f8f281ab028d2c70. but to make it more secure like what IPB does it to double encypt it. so it looks like this:
this will output: a932721fa7514980123ca95f1e94cb47 which is harder to crack becuase it is an encrytption of an encryptiom.
hope that helps.
PHP:
$text="test text";
$encrypted= md5($text);
echo $encrypted;
PHP:
$text="test text";
$encrypted= md5(md5($text));
echo $encrypted;
hope that helps.
