`RangeError: Offset is outside the bounds of the DataView` when trying to encrypt with AES-CRT
Hi, I'm trying to encrypt some files with aes128-crt, but I always get the error below. (Even if I just pass some random short string converted into an uint8array instead of the file's content)
stacktrace:
