Crypto related functions and helpers for Swift implemented in Swift. (#PureSwift). Note: The main branch follows the latest currently released version of Swift. If you need an earlier version for an older version of Swift, you can specify its version in your Podfile or use the code on the branch for that version. Older branches are unsupported.

I've managed to get your cipher text decrypted using only Apple provided sources. If you support iOS 13 and up, I suggest you use
CryptoKit to verify the HMAC, but for now, I've adopted a full
First a minor extension to create
Data from base64 URL strings.
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:...

encrypt() method the IV is not considered. As in
aesEncrypt(), the IV must be passed and used when creating the AES object.
Furthermore there are bugs in the encoding: The plaintext must be UTF8 encoded and the ciphertext must be hex encoded:
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:...

The name of the pod and resource bundle being the same causes issue. Try putting a unique name for the resource bundle
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-1220.127.116.11 clang-118.104.22.168)', 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:...

It turns out that this pod was causing the problem:
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....

Here's a short extension over
Data for removing the trailing zeros:
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):
ANSWERAnswered 2021-Aug-22 at 19:35
How can I improve it to make it (a lot) quicker?
Don't use bytes. Performance depends on the number of "digits" in the big numbers; so more smaller digits is worse and fewer larger digits is better. For example, for multiplying a pair of 2048-bit big numbers, if it's implemented using bytes you end up with "256 digits * 256 digits = 65536 multiplications of digits" and if it's implemented with 64-bit integers then you end up with "32 digits * 32 digits = 1024 multiplications of digits" (which is about 64 times faster).
Prefer destructive operations
For big numbers; for something like "a = b + c" the CPU has to deal with 3 sets of cache lines, and for something like "a += b" the CPU only has to deal with 2 sets of cache lines. For large big numbers this can be the difference between "it all fits in cache" and "performance is ruined by cache misses".
Don't use append
bytes.append(r) probably involve a buffer capacity check and potential resizing of the underlying buffer; and this extra overhead is unnecessary and avoidable - you should be able to determine the size of the result in advance, create a correct size array in advance, then calculate the result without any checks and without any resizing.
Don't use multiplication for squaring
For squaring, the number of "multiplications of digits" can be almost halved by relying on the fact that both numbers are the same number. To understand this, assume you're doing 1234 * 1234 in decimal and express the intermediate values a grid like this:
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.

run pod deintegrate then remove podfile.lock then pod install then set build active architecture to yes also, it maybe help if u put this at the end of pod file
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....
ANSWERAnswered 2021-Jun-18 at 13:25
WordArrays, so that key, IV and ciphertext have to be converted accordingly. For this purpose the appropriate encoders have to be applied. Furthermore
decrypt() expects the ciphertext as
This results in the following possible CryptoJS implementation:

The problem was with flutter_pusher_client: ^0.3.1 and laravel_echo: the packages not updated and they use an old version of Cryptoswift and get failed in build.
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:...
ANSWERAnswered 2021-Mar-25 at 05:31
Recently, I've also done upgrade from Xcode 11.7 to 12.4 and got the same
Segmentation fault: 11 error on so many
Swift files in my project and the weird part is, most of the times those error doesn't have proper description or reasoning.
I have spent around a week on this and found a solution which worked for me.
BUILD setting called
SWIFT_COMPILATION_MODE, just set this property to
Whole Module and build your project. Now XCode will start giving you error with some understandable description. You can go ahead fix those error.
Once you resolved these errors, you can set this property back to it's previous value i.e.
NOTE: It still won't give you the error line number but it will give you the class & method name where this error lies, also the error count will get reduced to the actual count. You can comment all the lines in that function and try to uncomment one (or more) at a time and build your project to find out the problematic line.
This is how I'm able to resolved these errors, hope this helps you in resolving yours.
