You need to use the new keyword to call the constructor and create the object. SecretKey originalKey = new SecretKeySpec(encodedKey, 0, encodedKey.length, “AES”); When you try to call it without new, the compiler thinks it might be a method you’ve defined inside that class, hence your error message.
There is no real perfect solution. No matter what you do, someone dedicated to it will be able to steal it. Even Twitter for iPhone/iPad/Android/mac/etc. has a secret key in there, they’ve likely just obscured it somehow. For example, you could break it up into different files or strings, etc. Note: Using a hex editor … Read more
Let me try to break down your question to multiple subquestions/assumption: Assumptions: a) Keychain is safe place Actually, it’s not that safe. If your application is installed on jailbroked device, a hacker will be able to get your keys from the keychain Questions: a) Is there a way to put some key into an app … Read more
If you use a block-chaining mode like CBC, you need to provide an IvParameterSpec to the Cipher as well. So you can initialize an IvParameterSpec like this: // build the initialization vector. This example is all zeros, but it // could be any value or generated using a random number generator. byte[] iv = { … Read more
As of Laravel 5.5.13, you can censor variables by listing them under the key debug_blacklist in config/app.php. When an exception is thrown, whoops will mask these values with asterisks * for each character. For example, given this config/app.php return [ // … ‘debug_blacklist’ => [ ‘_ENV’ => [ ‘APP_KEY’, ‘DB_PASSWORD’, ‘REDIS_PASSWORD’, ‘MAIL_PASSWORD’, ‘PUSHER_APP_KEY’, ‘PUSHER_APP_SECRET’, ], … Read more
You need two separate keys, one that tells them who you are, and the other one that proves you are who you say you are. The “key” is your user ID, and the “secret” is your password. They just use the “key” and “secret” terms because that’s how they’ve implemented it.
I’ve been playing with tokens for my application as well. While I’m not an expert by any means, I can share some of my experiences and thoughts on the matter. The point of JWTs is essentially integrity. It provides a mechanism for your server verify that the token that was provided to it is genuine … Read more
Basically elaborating on what’s outlined here. Here’s how it works: let’s say we have a function that takes a number from zero through nine, adds three and, if the result is greater than ten, subtracts ten. So f(2) = 5, f(8) = 1, etc. Now, we can make another function, call it f’, that goes … Read more
