encode and decode data with key

@Sinnbeck I am writing API in Laravel I need send return response in encoded format and decode will be done in react js will this supports in react js?

@Shawdow Whats the point of encoding/encrypting it then? I can just grab your key from react and decode it myself?

@Sinnbeck how to restrict decoding. any idea for this? encoding data in return response and decode the data only if the send valid key to decode!!

@Shawdow Why is it needed?

@Sinnbeck to make the data protected. user should not use the data.

@Shawdow Just dont send any data that you don't want them to see? I mean you can encrypt/encode it but I cannot think of a way to make 100% sure that no-one can decrypt/decode.. If you want make sure that the user sees nothing, use pure blade.

@Sinnbeck user's should use headers data.when API call happens. i want to protect this from the user side.If the users sees the data in headers he should not be able to decode data. this is what i am trying to do.

@Shawdow I cannot see any way that you can protect this 100% as all javascript is run using the users browser. So they have access to all of the react/js code. You can make it harder by doing multiple encodings, or spreading the key across multiple files etc. but that is still not 100%

@Sinnbeck thanks for the Information!
