[secuity]Insecure Random Number Generation for Passwords Poses Security Risks

[cryptochecktool]

The generatePassword function currently utilizes Math.random() to generate passwords. However, Math.random() is not a secure method for generating random numbers as it is a pseudo-random number generator, which is susceptible to prediction and attacks. This can lead to security issues when generating sensitive information such as keys.

Reproduction Steps:

Inspect the implementation of the generatePassword function.
Notice that the function uses Math.random() to generate the random password.
Expected Behavior: A secure random number generation method should be used to generate passwords to ensure their strength and security.

Actual Behavior: The current implementation uses the insecure Math.random() method to generate passwords.

Suggested Fix: It is recommended to use the crypto.randomBytes() method from the crypto module to generate secure random numbers. Below is an example of the modified generatePassword function:

const crypto = require('crypto');

module.exports.generatePassword = () => {
var length = 12,
charset = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789',
retVal = '';
const bytes = crypto.randomBytes(length);
for (var i = 0; i < length; ++i) {
retVal += charset.charAt(bytes[i] % charset.length);
}
return retVal;
};
Please consider adopting the above suggestion to enhance the security of password generation. Thank you!
