encryption | Encryption Algorithm | Encryption library

I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too. I believe it's something with Redis, as I'm using it to store the system cache. When I go to access my endpoint in postman it returns the following error:

I am trying encrypting in JS front end and decrypt in python backend using AES GCM cryptographic algorithm. I am using Web cryptography api for JS front end and python cryptography library for python backend as cryptographic library. I have fixed the IV for now in both side. I have implemented encryption-decryption code in both side, they work on each side. But I think the padding is done differently, can't seem to figure out how the padding is done in web cryptography api. Here is the encryption and decryption for the python backend:

I am new to SwiftUI (iOS App Ver 14.x) as I normally use Xamarin.

In this case I need to have the application specifically written in SwiftUI. (I am aware that some stuff still needs UIKit).

I have got my head around it though I am generally speaking struggling to get to grips with where and how to store stuff.

For example (greatly simplified) let us say I want the following:

All in the same view.

Two form fields:

First Name: … Last Name: …

A Button that says, “Add Photo”.

A Button that says, “Save Locally” (N/a but just for info, to be later uploaded to a web service that isn't always available at some point).

Now doing all the standard stuff this is pretty straight forward.

BUT.

I want to encrypt the form input (once converted to JSON, note I can convert to JSON easy enough).

I also want to encrypt the image before it is stored. (the real app has more than one image).

The stuff will be encrypted in the real app using asymmetric encryption (which I understand well, again this is not so relevant here).

But for the sake of example, I am happy to just ‘encrypt’ the JSON and picture as two separate files using something simple just to show the idea. XOR it or something simple to show.

My question is where is the best places code wise to do this with some basic examples if possible. I know this is a little subjective but just something simple and obvious. Click button, run this func, do this type of thing etc.

Where do I store stuff (which I am finding a bit all over the place)? This is my main source of confusion being honest.

My understanding is that you would use a FileManager object and the documents directory (though I am not sure if this is best practice, or even the right place.

The requirement from a client is that nothing is stored unencrypted for compliance reasons (completely ignoring anything Apple have in place good or bad).

trying to mount EFS to ECS Fargate but getting below error while task is being executed. it looks as though it is an IAM issue but crosschecked all the roles and unable to identify the issue. Checked security groups as well.i allowed 2049 port and attached ecs security group to it.

I am trying to use kafka rest proxy for AWS MSK cluster.

MSK Encryption details:

Within the cluster

TLS encryption: Enabled

Between clients and brokers

TLS encryption: Enabled

Plaintext: Not enabled

I have created topic "TestTopic" on MSK and then I have created another EC2 instance in the same VPC as MSK to work as Rest proxy. Here are details from kafka-rest.properties:

I am new to Oracle SQL,

And have following requirement,

There is a customer table with following columns,

So I tried to read the file and encrypt its content with cryptography.fernet but sometimes the file contains characters that can't be encrypted by whatever algorithm is being used in this library. I also tried a library called pyAesCrypt which has this function: pyAesCrypt.encryptFile("data.txt", "data.txt.aes", password). But it also can't encrypt some file types like gifs. I don't know much about the encryption algorithm happening in the background, but is there any way I can encrypt all files no matter what characters they contain? Or maybe encode them first to get rid of these characters then encrypt them? I'm just giving ideas based on the small knowledge I have about this topic.

The code I tried with Fernet library:

I'm new to PGP encryption and I'm trying to understand a problem I'm having. I have this public key (taken from some examples online)
