QUESTION
Sorry for my English, I am not a native speaker).
I have two custom HTML elements: SignUpForm (parent) and CustomInput (child). In SingUpForm I validate inputs - check if it is empty. If it is, I set attribute error-text
via element.setAttribute(name, val), then I "catch" this change in CustomInput, and set validation texts in span
.
But after validation and calling elem.setAttribute(name, val) my CustomInput doesn't react on this changes. I can not understand why. What am I do wrong?
Below you can see my custom elements and BaseComponent - is parent class for both of them.

returns your custom inputs nested (native) input which gets the same name
as the custom input.
You're just setting your attribute on the wrong element (native input) and in turn the attributeChangedCallback
is never called.
QUESTION
In my Objective C code, I have a consumer key and secret hardcoded in my code to be used in SHA-1 encryption. What I would like to know is whether I could avoid hardcoding to improve security. I have found the following so far,
Finding 1 https://www.owasp.org/index.php/Technical_Risks_of_Reverse_Engineering_and_Unauthorized_Code_Modification#Cryptographic_Key_Replacement Steps explained are as follows,
Damage static keys that are declared in source code. Such keys should be damaged while on disk to prevent an adversary from analyzing and intercepting the original key;
Next, the application should repair the key just before the code requiring the key uses it;
Immediately before use of the key, the application should perform a checksum of the key’s value to verify that the non-damaged key matches the value that the code declares at build time; and
Finally, the application should immediately re-damage the key in memory after the application has finished using it for that particular call.

Can somebody help me please?

Answered 2017-Jun-22 at 11:28So I recommend use yours second finding
and add the regenerated strings to the keychain at the first application launch
so all methods could use values from keychain later in you code. also I recommend build a singleton that will provide access to such values too keep all in one for time you want to change or update this solution
In general I wrote may api keys just inline in code, sometime declare them split it into two parts for safety. I am using a brain factor;)
let's say you API key xxx-xxxx-xxxx I code the string xxx-xxxx-xFFF which as you see has same length as right key, somewhere in other method I cut las FFF and append right xxx postfix.
If you have a paranoia you could do it in different classes that defined in same file for convenience but stays alphabetically different places like AStoredKeys TheRightPostfixes that somehow hides your approach from disassemblers.
