These instructions cover Paramiko 2.0 and above. If you’re looking to install Paramiko 1.x, see Installing (1.x). However, the 1.x line relies on insecure dependencies so upgrading is strongly encouraged.
The recommended way to get Paramiko is to install the latest stable release via pip:
$ pip install paramiko
We currently support Python 2.6, 2.7, 3.3+, and PyPy. Users on Python 2.5 or older (or 3.2 or older) are urged to upgrade.
Paramiko has only one direct hard dependency: the Cryptography library. See Cryptography.
If you need GSS-API / SSPI support, see the below subsection on it for details on its optional dependencies.
Users desiring stability may wish to pin themselves to a specific release line once they first start using Paramiko; to assist in this, we guarantee bugfixes for the last 2-3 releases including the latest stable one.
This typically spans major & minor versions, so even if e.g. 3.1 is the latest stable release, it’s likely that bugfixes will occasionally come out for the latest 2.x and perhaps even 1.x releases, as well as for 3.0. New feature releases for previous major-version lines are less likely but not unheard of.
If you’re unsure which version to install:
- Completely new users should always default to the latest stable
release (as above, whatever is newest / whatever shows up with
pip install paramiko.)
- Users upgrading from a much older version (e.g. 1.7.x through 1.10.x) should probably get the oldest actively supported line (check the Changelog for recent releases).
- Everybody else is hopefully already “on” a given version and can carefully upgrade to whichever version they care to, when their release line stops being supported.
In general, you’ll need one of the following setups:
On Windows or Mac OS X, provided your
pipis modern (8.x+): nothing else is required.
pipwill install statically compiled binary archives of Cryptography & its dependencies.
On Linux, or on other platforms with older versions of
pip: you’ll need a C build toolchain, plus development headers for Python, OpenSSL and
libffi. Again, see Cryptography’s install docs; these requirements may occasionally change.
If you go this route, note that OpenSSL 1.0.1 or newer is effectively required. Cryptography 1.3 and older technically allow OpenSSL 0.9.8, but 1.4 and newer - which Paramiko will gladly install or upgrade, if you e.g.
pip install -U- drop that support.
Optional dependencies for GSS-API / SSPI / Kerberos¶
In order to use GSS-API/Kerberos & related functionality, a couple of
additional dependencies are required (these are not listed in our
due to their infrequent utility & non-platform-agnostic requirements):
It hopefully goes without saying but all platforms need a working installation of GSS-API itself, e.g. Heimdal.
Unix needs python-gssapi
This library appears to only function on Python 2.7 and up.
Windows needs pywin32
If you use Microsoft SSPI for kerberos authentication and credential delegation, make sure that the target host is trusted for delegation in the active directory configuration. For details see: http://technet.microsoft.com/en-us/library/cc738491%28v=ws.10%29.aspx
