Code Examples
Compliant code
The OTP service is securely configured, verifying the uniqueness of the code generated
const otpGenerator = require('otp-generator');
const { OTP_LENGTH, OTP_CONFIG } = require('../constants/constants');
//Implement a secure version of the OTP generator
module.exports.generateOTP = () => {
const OTP = otpGenerator.generate(OTP_LENGTH, OTP_CONFIG);
return OTP;
};
OTP_CONFIG: {
upperCaseAlphabets: true,
specialChars: false,
},
Non compliant code
The OTP service is insecurely configured to allow default access
const otpGenerator = require('otp-generator');
const { OTP_LENGTH, OTP_CONFIG } = require('../constants/constants');
//The code still contains the default OTP used during development
module.exports.generateOTP = () => {
const OTP = "OneTimeValue";
return OTP;
};
OTP_CONFIG: {
upperCaseAlphabets: true,
specialChars: false,
},
