how to get 16 digit random password using PwdCryptoSecureAutoGenPassword() ?

[saranyavs]

Hi team,

I am using below script to generate random password, and its generating 10 digit password by default.

Can we get 16 digit random password instead of 10?

===========================

         var encr= new GlideEncrypter();

                var clearString = new PwdCryptoSecureAutoGenPassword().generatePassword();

                var encrString = encr.encrypt(clearString); 

                workflow.scratchpad.pass = encrString;  

                var decrString = workflow.scratchpad.clearpass = encr.decrypt(encrString);  

=============================

Regards,

Saranya

My thoughts

1) OOTB that function will give password between 8 to 12

2) if you want to increase to 16 then you will have to update the OOTB script include -> Not recommended way

Another way is to use that script and use directly and then enhance to generate between 8 to 16

something like this

function insertCharacterAtIndex(str, c, idx) {
    return (str.slice(0, idx) + c + str.slice(idx));
}
var encr = new GlideEncrypter();
var specialCharacters = " !\"#$%'()*+,-./:;=?@[\\]^_`{|}~";
var secureRandom = GlideSecureRandomUtil;

// Decide number of special characters you want (e.g. 3)
var numSpecialCharacters = secureRandom.getSecureRandomIntBound(3) + 1; // 1-3 special characters
var pwdBaseLength = 16 - numSpecialCharacters; // so final length is 16
var newPwd = secureRandom.getSecureRandomString(pwdBaseLength);

for (var i = 0; i < numSpecialCharacters; i++) {
    var idx = secureRandom.getSecureRandomIntBound(newPwd.length + 1); // insert in any position
    var c = specialCharacters.charAt(secureRandom.getSecureRandomIntBound(specialCharacters.length));
    newPwd = insertCharacterAtIndex(newPwd, c, idx);
}

var encrString = encr.encrypt(newPwd);
workflow.scratchpad.pass = encrString;
var decrString = encr.decrypt(encrString);

in this example is used with 100 characters but you can configure for 16
