Bug report: AES 256 CTR wrong encrypt/decrypt

See original GitHub issue

With version v9.0.0 if you encrypt/decrypt a file with:

AES-256
Mode: CTR
Input/Output: RAW
Key/IV: HEX the output file has a wrong size (more byte/Mbyte) and it is not encrypted correctly. With version v8.38.2, with the same file and configuration, all work fine.

To Reproduce Configuration:

[
  { "op": "AES Encrypt",
    "args": [{ "option": "Hex", "string": "603deb1015ca71be2b73aef0857d77811f352c073b6108d72d9810a30914dff4" }, { "option": "Hex", "string": "f0f1f2f3f4f5f6f7f8f9fafb00000000" }, "CTR", "Raw", "Raw"] }
]

Input file: text file with 16byte (es: “1234567890123456”)

This has been fixed in version 9.0.1. It was caused by the File API converting strings to UTF-8, so to fix this we now only pass data to the File API as an ArrayBuffer.

Ok, I can confirm that the downloaded file is incorrect. Thanks for raising this, I’ll see what the problem is.
