i tried below code using api url but it is not working ....  {"result":"error","message":"Error generating JSON encoded response: Malformed UTF-8 characters, possibly incorrectly encoded"}

Also if password length is less ... then it like works please suggestions ...

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com/includes/api.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
    http_build_query(
        array(
            'action' => 'DecryptPassword',
            // See https://developers.whmcs.com/api/authentication
            'username' => 'IDENTIFIER_OR_ADMIN_USERNAME',
            'password' => 'SECRET_OR_HASHED_PASSWORD',
            'password2' => 'vNRQzRPKQA6obJpHMHCBivS0D9/Pf532oArYvewP',
            'responsetype' => 'json',
        )
    )
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

You could try to use mb_convert_encoding before you decrypt password.

$password2 = mb_convert_encoding('vNRQzRPKQA6obJpHMHCBivS0D9/Pf532oArYvewP', 'UTF-8', 'UTF-8');

For more info about params (I don't know what's you "from_encoding") you can take a look here.
