CryptoSwift | growing collection of standard and secure cryptographic | Cryptography library

I am using CryptoSwift 1.4.1, iOS 15.2, PyCryptodome 3.12.0, and XCode 13.2.1 to encrypt small string messages that I send to a Raspberry Pi Linux Device over BLE. It works when iOS encrypts the message and sends it to the Raspberry Pi. The Pi can successfully decrypt it. Now I want to do the inverse, encrypt a message on the Pi and have the iOS App read and decrypt it. This, however is not working and the decrypted value is the not the message I encrypted on the Pi.

Working iOS encryption:

I've got a project made by modules and each module is a cocoapods library that loads each section of the App.

This application was made 1 and a half years ago and it has been maintained and it's been working without problems but now i just had to do an small change (the first change that i did to this app using Xcode 13) and the problem is that when i compile in my iPhone, iPad, or any simulator, everything works perfectly, but when i send the app to TestFlight, the colors and the images contained inside the modules (cocoapods libraries) doesn't appear. The views and the languages are working but not the colors and the images (that colors and the images of each module are inside an xcassets included in the module itself).

This is the podspec of my modules:

So I cloned an existing repository from GitHub and tried the pods on my device(MacBook Pro M1 2020 bigSur 11.6 and Xcode 13) Cocoapods was not working as expected so I looked it up online and after trying to open using Rosetta and installing ffi gem I managed to install most of the pods. However, these 2 errors keep showing up:

• No such module 'MapboxCommon_Private'
• Failed to build module 'MapboxSearch'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.4.2 (swiftlang-1205.0.28.2 clang-1205.0.19.57)', while this compiler is 'Apple Swift version 5.5 (swiftlang-1300.0.31.1 clang-1300.0.29.1)'). Please select a toolchain which matches the SDK.

The pod file looks like this:

I have below function where I try to decode(base64), decrypt and create JSON dictionary,

However, I get an error called NSCocoaErrorDomain Code=3840 "Garbage at end." for some unknown reason decryption creates \0\0\0\0\0\0 at the end of the JSON string (probably padding). I am using CryptoSwift to decrypt the response. I am unable to find a way to make this works, as should be pretty straight forward but i am missing something important step in my code.

I'm trying to implement a RSA algorithm in Swift for the CryptoSwift lib (to fix #63). The algorithm itself is working, but I need to improve big numbers computation performance for it to work in reasonable time.

I implemented my own GiantUInt struct (storing bytes as UInt8) to compute operations with RSA big numbers (2048 bits length for example), but it is too slow (mainly the remainder operation, but I think everything can be improved):

When I try to archive an app on Xcode, I receive many errors regarding the cocoa pods saying that "multiple commands produce...". I believe it is because the app has multiple build schemes using the same cocoapods. One app from the project was able to archive, but the other scheme that I created won't work.

Errors:

I am encrypting a text with AES256 in swift language and outputting it as hex. I want to decrypt this code I received with JS, but I could not reach the result. I tried the CryptoJS library but still couldn't get the result I wanted. All I want is the js code that will give me the decoded version when I enter the IV, password and ciphertext.

when Xcode updated the last version 12.5 when I build IOS app it failed because of flutter and pods Cryptoswift

I tried to pod update but it downloads 0.15.0 not the last version of Cryptoswift

We have updated the xcode version 11.6 to 12.4 last week. Everything was working perfectly. After this update, We are getting this issue. We tried these steps:
