• How to silence EllipticCurvePublicNumbers.encode_point CryptographyDeprecationWarning when using Paramiko in Python 2 answers

I keep getting the following deprecation warnings when doing simple SSH connections:

2019-03-04 02:21:14 [transport] INFO : Connected (version 2.0, client OpenSSH_7.4)
/usr/local/lib/python2.7/site-packages/paramiko/kex_ecdh_nist.py:39: 
  CryptographyDeprecationWarning: encode_point has been deprecated 
  on EllipticCurvePublicNumbers and will be removed in a future 
  version. Please use EllipticCurvePublicKey.public_bytes to obtain 
  both compressed and uncompressed point encoding.
m.add_string(self.Q_C.public_numbers().encode_point())

hm.add_string(self.Q_C.public_numbers().encode_point())
2019-03-04 02:21:14 [transport] INFO : 
   Authentication (keyboard-interactive) successful!

This more of an annoyance, as the program runs successfully, any ideas on how to get rid of these messages?

I am using Paramiko 2.4.2 with Python 2.7.9.

This has been fixed in Paramiko already:
https://github.com/paramiko/paramiko/issues/1369
https://github.com/paramiko/paramiko/pull/1379
Bug the fix was not released yet.

Meanwhile, you can workaround it by downgrading cryptography:

pip install cryptography==2.4.2
