How to solve "dataPaddingRequired" error CryptoSwift

Question

I have key = "somesomesomesome".md5(), length is 32 bytes, iv is empty, trying to decrypt encrypted string using CryptoSwift:

let aes = try AES(key: key.bytes, blockMode: CBC(iv: []), padding: .noPadding)
let result = try aes.decrypt(encrypted)
let decrypted = String(bytes: result, encoding: .utf8)

getting error "dataPaddingRequired". What I am doing wrong?

Step 1. Don't use CryptoSwift, use CryptoKit or SwiftSodium. CS is awful. — Woodstock, Oct 27 '19 at 18:39
@Woodstock or even better, use Apple's own solution, [CryptoKit](https://developer.apple.com/documentation/cryptokit) — Dávid Pásztor, Oct 27 '19 at 18:41
@DávidPásztor yup - said that , Cryptokit. SwiftSodium is better if using non NIST curves such as 25519 — Woodstock, Oct 27 '19 at 18:43
CryptoKit available only for iOS > 13.0, my target is 11.0, please help me find AES256 usage example of SwiftSodium — zzheads, Oct 27 '19 at 18:54
Is your plaintext's length an exact multiple of 16-bytes? If not, how does your encryptor handle this? What is the code used to create this cipher text? — Rob Napier, Oct 28 '19 at 03:00

Add this before setting up your AES:

let padding = Padding.noPadding.add(to: encrypted, blockSize: AES.blockSize)
