A hundred secrets and a few secrets - Caesar encryption

Title Description ：

That's about it , I can't tell you any more ...

Ideas ：

This jumble of code looks like ASCII code ,ASCII Code used in total 7 digit , So the string is 0~127（） Second shift for observation , Then filter out miscellaneous items , Then there are some strings left and they look garbled , At this time, consider using base64 Code to decode try , Finally, it is found that a decoded string has practical significance .

import base64

lstr=r"""U8Y]:8KdJHTXRI>XU#?!K_ecJH]kJG*bRH7YJH7YSH]*=93dVZ3^S8*$:8"&:9U]RH;g=8Y!U92'=j*$KH]ZSj&[S#!gU#*dK9\."""
 
for p in range(127):
    str1 = ''
    for i in lstr:
        temp = chr((ord(i)+p)%127)
        if 32<ord(temp)<127 :
            str1 = str1 + temp 
            feel = 1
        else:
            feel = 0
            break
    if feel == 1:
        try:
            print("%d : %s"%(p,base64.b64decode(str1))) 
        except:
