我正在一个项目中使用 tkinter 进行加密解密程序，我使用 rsa 模块进行加密解密处理。但我在解密时遇到此错误：
No PEM start marker "b'-----BEGIN PUBLIC KEY-----'"这是我的解密函数：
import rsa
def decrypt(text, private_key):
try:
decryptedText = rsa.decrypt(text.encode('utf8'), rsa.PrivateKey.load_pkcs1(private_key))
return decryptedText.decode('utf8')
except Exception as err:
print(err)
return ''
我从 tkinter openfile dialogs 得到了我的输入 文本：*.txt文件 private_key: *.pem 文件
我正在从印刷中回收这个：
