What about decryption?
Sorry, I am not permitted to answer that question in more detail than "Call your decryption routine"
Once you have decrypted to a character vector then
bytes = uint8(decrypted_content);
filename = 'restored_image.tif';
[fid, msg] = fopen(filename, 'w');
if fid < 0; error('Could not open file "%s" for writing because "%s"', filename, msg); end
fwrite(fid, bytes, 'uint8');
fclose(fid)
The extension you use for filename should be the same as the original image file extension.
