how to decrypt encrypted text to a clear text

[blue]

Test again your chain programming way , because :
>>> dir(RSA.importKey)
['__call__', '__class__', '__cmp__', '__delattr__', '__doc__', '__format__', '__func__', '__get__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__self__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'im_class', 'im_func', 'im_self']
>>> dir(RSA.importKey.decrypt())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'function' object has no attribute 'decrypt'
