一道密码学求解

请解密这段密文:
FqsCFkufDSQgSf4NSgWFGPvMP6FCHwg=



这是泄漏的一段明文:
!QAZ@WSX#EDC$RFV%TGB^YHN&UJM*IK<(OL>)P:?_{"+}|`1qaz2wsx3edc4rfv5tgb6yhn7ujm8ik,9ol.0p;/-['=]\The problem is that programs_width is a list. programs_width = list(). If none of these if statements if prog_width == '342' When you read an English book, you often come across new words. You might try to guess what the words mean from the words you know, but when you cannot guess the meanings of new words at all, what should you do?

老哥，求wp

主要就是看泄露明文和密文之间的字符转换关系，搞清楚了就解出来了
