LEVEL ONE:

Step 0) We deobfuscated the crypto.js file and ran it thru a beautifier to make the code more readable.

Step 1) encrypt(form) function:
Upon submitting the form a call is made to encrypt(form) where the value from the textbox is extracted and sent to a function called numerical_value(str) which returns a numerical representation of the input string.

function encrypt(form) {
	var res = numerical_value(form.password.value);
	res = res * (3 + 1 + 3 + 3 + 7);
