Code Hash Function Over Data In Form - Already Have Function But Don't Know Where To Call

Question

I have form in my html page

Copy

JavaScript

function myOnSubmit(aForm) {
    //Getting the two input objects
    var inputUsername = aForm['username'];
    var inputPassword = aForm['password'];

    //Hashing the values before submitting
    inputUsername.value = sha256_hash(inputUsername.value);
    inputPassword.value = sha256_hash(inputPassword.value);

    //Submitting
    return true;
}

EDIT : Because of the 'Hashing the values before submitting' part, it will not work if you have a maxlength property, because hashed values are much longer than just the clear password.

If you MUST use a maximum length, then you would need to implement HIDDEN FIELDS and changing those values, and making sure the fields containing the clear data aren't submitted (outside of the <FORM> tag).

Solution 2:

<button dojoType="dijit.form.Button"  class="soria" style="border: 1px solid black; float:right;" type="submit" onclick="username.value=sha256_hash(username.value);password.value=sha256_hash(password.value)">Login</button></td>

Generally when you send sensitive data, you have only to worry about password, so you can hash password and leave user as it.
