Password Validation In Java

[Kum Verna]

Wewere asked to make a subscription type of form. Details needed are username, password, first name, last name, etc. My problem has something to do with the password validation. when i feel in the password field and the re-type password field, both of them should be checked. If both are the same, it will be redirected to a "success page" after clicking the submit button. But if both passwords don't match, a short "error page" should be included and displayed at the bottom of the same page after clicking the submit button. I can't get it to include the short error page on the same page after clicking the submit button. I am using "IBM RAD" for this. Here's what I've got so far:

Try to run that code and see what happens. The "pass2" string will always be equal to "pass2" string.

You write: "pass2".equals("pass2") . Those are fixed values and it is always true. And the ! will always make it false.

The first time you go to that page for the user to enter the values, the request is empty, so the password1, password2 would be null and the validation will not take place. But when you submit, you will send the pass1, pass2 values of the input fields and you will do the validation. I trust that exer02-b.jsp is the file that you posted. Remember the page that you enter at the action attribute of the form is where the values are sent.

Thanks for the code. It works. However I have another problem. I want it to output an error message if i did not fill in any of the blanks nor selected a gender.

I tried the following code for example:

You must always check if those values are null or not.

When you first go to that page, they are null, since you didn't submit anything.

After you check that they are not null, then do whatever validations you want.

I would suggest to use only one, the user for example. If it is not null, it means that the others were given as well.

Also for the radio button if don't select anything it submits null, so you can use that to check if the user hasn't entered anything. And add the value attribute to the radio button.

I remember trying a code similar to the one above that didn't give me an error. When I open the mainpage.jsp, it doesn't wait for me to click the submit button on that page but instead it directly forwards me to successpage.jsp. How can this be prevented from happening?

Password validation is the need of almost all applications today. There are various ways to validate passwords from writing everything manually to using third-party available APIs. In this password validation tutorial, we are building a password validator using regular expressions.

We are making our validator configurable so that one can put the limits based on needs. Like if we want to force at least one special character, but not any capital letter, we can pass the required arguments accordingly.

Given the code, is it possible to add a password validation field to the DB? Or just completely unnecessary? (note: I cannot run the code myself as there a bunch of errors with bcrypt that bcrypt.js workarounds aren't fixing for me, hence the question)

Here is my line of thought, if the user mistypes their password, this db entry has no validation to account for that and to my understanding the db entry is created which means its created with a potentially bad password from the users perspective.

Is it possible to create an extra field within the schema object that ensures 'password' === 'password confirmation', else "reject" the entire entry and alert the user to reenter or something like that?

The validation you're referring to is actually implemented later in the course. Maybe you haven't got there yet. If you have completed the course, then look in the POST route for "/register." There, you will find the following check that makes sure the user's first password matches their second password:

Thank you! I'm going to go back through that piece because I didn't catch it when I went through it. Saving the code in my notes - thanks!The deeper question that I had is a no though I guess, you can't save something like a count of how many times a user had to try to set up their password before keying it correctly and getting a match because they don't have a "session" or way to store that info prior to having a db entry....right?

A password confirmation field normally wouldn't be stored in the database. It's only ever used one time, when you set or reset the password. Since it should be exactly the same as the password, there is no reason to store it and it would be duplicate data.

Not to store "it" itself but rather to store the fact that it matched the first time input...validate it before creating a db entry (before allowing one to be created) by confirming the two match if that makes sense. I've seen this appear as a check box (that yes it did match the first time) in other database applications where security, records, and accountability and even the Business Intelligence behind that fact, matter a bit more. My thinking is that it'd be similar to confirming that a EULA entry has been accepted.

I may be over thinking it for this matter (a sign up form) but the question is valid - is it possible? Perhaps its further in the course, I'm still going through it and we have not yet gone over what that confirmation field is actually spec'd to do.

We want to allow our users to change their Active Directory passwords via Keycloak. We changed the Edit mode of the federation provider to WRITABLE and toggled the Validate password policy switch on. Basic constraints like password length and complexity are enforced, but some of the password constraints set in AD are not enforced:

This is the same behavior as when Validate password policy was toggled off. Keycloak version is 20.0.1 and AD is running on a Windows Server version that should support the LDAP_SERVER_POLICY_HINTS_DEPRECATED_OID. We are not using AD LDS.

My assumption is that the new admin UI might not be properly triggering the Validate password policy option. Is anyone else experiencing this? Or are we missing some configuration? We tried activating the Enable the LDAPv3 password modify extended operation toggle in addition but that did not change anything.

I read up on the topic and also found a mailing list thread which pointed me to an old JIRA issue for this problem which was fixed. Here is a bit of background I learned on the way. Unfortunately I had to remove some links as new users can only add two links to a post. I replaced links to the source code on GitHub with the file name and line number and will add missing links to a follow up post.

While doing some testing with the legacy admin UI we saw that the information for the Validate Password Policy switch is a little bit more detailed there. According to that info it only turns on/off policy validation on the Keycloak side, so turning it on or off will not make any difference in our case. However, this would mean that the password replacement does not respect the passed OID in general.

Java Bean Validation, also known as JSR-303 (Java Specification Requests), is an annotation based validation specification for validating fields on objects. Java Bean Validation uses flexible annotations, which can be overridden or extended through the Java code or in an XML file, to apply validation constraints.

The validate(object) method returns a set of constraint violations. If this set is empty, the object passes validation. Otherwise, you can pass the constraint violations set to loggers or UI widgets to display validation errors.

By default, constraints do not validate in a particular order. However, you can specify a validation order by using validation groups. For example, you can create two groups to validate a country / sub-country relationship. In the first group, you verify that the country exists. In the second group, you verify the sub-country exists within the country.

Bean Validation allows you to apply constraints though XML files. This lets you override or extend validation constraints on Elastic Path domain objects, methods, and properties without having to replace or modify your code.

You have a custom validation constraint, named @RegisteredCustomerPasswordWithRegex, that matches passwords with regular expressions. To add @RegisteredCustomerPasswordWithRegex without modifying the out-of-the-box code, you can use XML.

Creating custom constraints enables you to validate objects against criteria specific to your needs. For example, you can require all passwords to include an uppercase letter, a lower case letter, and a digit.
