as3-otp

ActionScript3 implementation of the OTP/TOTP protocols. RFC4226 and RFC628 compliant, minus the error handling.

The only requirement is the as3crypto library for computing SHA-HMACS.

Examples

OTP (one-time-password)

var otp: OTP = new OTP(); // an optional secret key, period and output digit count can be passed here

var secret: String = otp.getSecret(); // the secret key used by the class
var digits: int = otp.getDigits(); // the amount of digits used in the output code

var code: String = otp.at(1337); // generate an OTP code with a given integer counter

TOTP (time-based one-time-password)

var totp: TOTP = new TOTP(); // an optional secret key, period and output digit count can be passed

var secret: String = otp.getSecret(); // the secret key used by the class
var digits: int = otp.getDigits(); // the amount of digits used in the output code

var codeNow: String = totp.now(); // get the generated code at the current time period
var codeCustom: String = totp.at(1605830400); // get the generated code for a custom unix timestamp
