Exception when code type is integer (expected string) #38

Actual behavior

While passing code parameter to verifyCode function and the code parameter is integer type the function crashes.

Expected behavior

verifyCode function verifies the code which is provided as integer.

Code to reproduce

$tfa = new RobThree\Auth\TwoFactorAuth("TEST");
$tfa->verifyCode("USJNHRTSCEAY2OME6IB7CLEE6HACYQGN", 123123);


$tfa = new RobThree\Auth\TwoFactorAuth("TEST");
$tfa->verifyCode("USJNHRTSCEAY2OME6IB7CLEE6HACYQGN", (string) 123123);


In case of the code starting by 0 the verifyCode function should prepend missing zeros based on the code generation length or drop the leading zeros from internal code generation. OR maybe just switch completely to integers as working with them is faster than strings = less cpu ticks = less co2 emission 🚭

Uh, no. The code is, and should be, a string. Just because it only contains digits doesn't make it an integer. You already discovered that leading zeroes will become a problem. Just like a phone number (which also, usually, only contains numbers) is a string, this verification code is supposed to be a string as well.

Also your argument about less cpu ticks is questionable at best. If we're measuring CPU cycles than the hash functions will use orders of magnitude more; switching to integers as an 'optimisation' is a micro-optimisation at best.

If anything, I should probably add typehinting someday and ensure all arguments are of the correct type.
