Rar file that you need to read each file one byte at a time to re-create jpg

Python Script:

file2 = open("F:/Crypto/Hive/file1", "rb")
file3 = open("F:/Crypto/Hive/file2", "rb")
text_file = open("F:/Crypto/Hive/Output.jpg", "wb")

with open("F:/Crypto/Hive/file0", "rb") as file1:
while True:
byte1 = file1.read(1)
byte2 = file2.read(1)
byte3 = file3.read(1)
text_file.write(byte1)
text_file.write(byte2)
text_file.write(byte3)
if not byte1:
break;

text_file.close()
print("Done")

Wow! How did the morse code help? It was the first thing I spotted. Where did you use RAID4NOPARITY?

RAID4 is needed to put the picture together from the 3 files. https://en.wikipedia.org/wiki/Standard_RAID_levels

Usually you include a parity disk, that’s why you actually use RAID system. In case a disk fails you can reconstruct it with the parity disk. However for this challenge I wanted to keep it a less complex and not include the parity disk

I know what RAID4 is but I couldn't make the connection, very smart way to hint the picture creation!

I would have never thought of that
