You can try to learn all of these skills yourself but it can be very time consuming and you will probably end up with a less than ideal final result. You can use something like [Twitters Bootstrap](http://getbootstrap.com/). Bootstrap is generally easy to learn and quick to get up and running. The main drawback is your site will look very similar to many other sites. Another option would be to hire a freelance designer. If you want a unique website this is one of the best options but comes with a few drawbacks. You need to find the designer, communicate your vision, then hope it turns out well while you wait for the work to be done. Also be prepared to pay a hefty price tag. Depending on your company size, branding and how unique you want to be it could very well be worth the money.

##Recommendations

* Purchase one or more themes but don't import the whole theme, just use it as inspiration. This allows you to keep the size of the assets smaller as well as switch to SASS or LESS if it's not provided.

* **Salted hashing** - Generating random bytes (the salt) and combining it with the password before hashing creates unique hashes across each users password. If two users have the same password they will not have the same password hash. This is to prevent [rainbow table](https://en.wikipedia.org/wiki/Rainbow_table) attacks which can reverse hashed passwords using common hashing functions that do not utilize a salt.

* **Logarithmic iterations** - The hashing function is executed many times sequentially which can be increased exponentially known as [key stretching](https://en.wikipedia.org/wiki/Key_stretching). This is to make the function CPU intensive which makes it more secure against brute force attacks.

* **Updatable iterations** - As CPUs become faster so do brute force attacks. Since BCrypt stores the number of iterations as part of the hash it's possible to verify a password and then increase its strength by generating a new hash with a higher number of iterations.

<p>Query Parameters and Path Parameters are also fairly straight forward in Undertow. There is some slight boilerplate because technically query and path params can have multiple values. We are using some helper functions (<a href="https://github.com/StubbornJava/StubbornJava/blob/master/stubbornjava-undertow/src/main/java/com/stubbornjava/undertow/exchange/PathParams.java">PathParameters.java</a> and <a href="https://github.com/StubbornJava/StubbornJava/blob/master/stubbornjava-undertow/src/main/java/com/stubbornjava/undertow/exchange/QueryParams.java">QueryParameters.java</a></p>
