I would like to use paramiko for SFTP file transfer in Python 3.5. I know that paramiko depends on PyCrypto and have read about PyCrypto installation problems in Python 3.5. Although I have seen a number of questions regarding this topic, I have not found a solution to successful SFTP file transfer in Python 3.5.

My first question: is it possible to use Python 3.5 for SFTP file transfer? If so, will paramiko work? If the above will work, why I am I receiving the following errors when attempting to install PyCrypto?

error: [WinError 2] The system canot find the file specified
**Failed building wheel for pycrypto**


My second question: if paramiko will not work with Python 3.5, are there any alternatives or must I revert back to a previous python version for SFTP file transfer?

The solution was to install Python 3.5.1 on my Linux server and then pip install paramiko from there. I'm still not sure why PyCrypto cannot be installed in Python 3.5 for Windows but this was the only solution I was able to find.

You can install PyCrypto binaries for Python 3.5 if you don't have a C++ compiler installed (that pip need to use to compile this library)

Install a PyCrypto binary from this site : https://github.com/sfbahr/PyCrypto-Wheels

The best way to do it, is:

64bits Python

c:\Python35\Scripts\pip.exe install --use-wheel --no-index --find-links=https://github.com/sfbahr/PyCrypto-Wheels/raw/master/pycrypto-2.6.1-cp35-none-win_amd64.whl pycrypto

32bits Python

c:\Python35\Scripts\pip.exe install --use-wheel --no-index --find-links=https://github.com/sfbahr/PyCrypto-Wheels/raw/master/pycrypto-2.6.1-cp35-none-win32.whl pycrypto

Of course replace c:\Python35\Scripts\pip.exe by your python pip path

To know your python version, run python and look at the architecture displayed between brackets:

C:\Users\utilisateur>python

Python 3.5.1 |Anaconda 4.0.0 (64-bit)| (default, Feb 16 2016, 09:49:46) [MSC v.1900 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

Hope this can help.
