v1.4: _openssl has no Cryptography_STATIC_CALLBACKS
by Robin Fishbein Sept. 28, 2016

Sept. 28, 2016

Hello, I imagine this may have a trivial explanation, or perhaps indicate some quirk on my machine, but it looks as though some desired functionality isn’t available on my machine with version 1.4. I wanted to share this in case it indicates some wider issue of interest, and helps me learn a little about how cryptography works under the hood. Windows 7, 64-bit, Python 3.5.1, and I believe OpenSSL 1.0.2. I use paramiko for SFTP, and when updating paramiko (on a whim) to 2.0.2 with Anaconda, it had me update cryptography as well, to version 1.4, or maybe it was 1.3 at first — either one experiences the issue. When attempting an SSH connect, I get a traceback ending with this: File "C:\Users\...\AppData\Local\Continuum\Anaconda3\lib\site-packages\cryptography\hazmat\bindings\openssl\binding.py", line 73, in wrapper if lib.Cryptography_STATIC_CALLBACKS: AttributeError: cffi library '_openssl' has no function, constant or global variable named 'Cryptography_STATIC_CALLBACKS' When I manually carry out some of the imports in the source... from cryptography.hazmat.bindings._openssl import ffi, lib ...and then look at what auto-complete shows for lib, I don’t see Cryptography_STATIC_CALLBACKS, which is consistent with the AttributeError. I don’t yet understand where to look for the source underneath the bootstrapped _openssl.*.pyd file. The SSH connection and all subsequent functionality work fine with the latest versions of paramiko and cffi as long as I revert cryptography to 1.0.2. -Robin Fishbein

by Paul Kehrer Sept. 26, 2016

Sept. 26, 2016

PyCA cryptography 1.5.2 has been released to PyPI. cryptography is a package which provides cryptographic recipes and primitives to Python developers. Our goal is for it to be your "cryptographic standard library". We support Python 2.6-2.7, Python 3.3+, and PyPy. Changelog: * Updated Windows and OS X wheels to be compiled against OpenSSL 1.0.2j. -Paul Kehrer (reaperhulk)

PyCA cryptography 1.5.1 released
by Paul Kehrer Sept. 22, 2016

Sept. 22, 2016

PyCA cryptography 1.5.1 has been released to PyPI. cryptography is a package which provides cryptographic recipes and primitives to Python developers. Our goal is for it to be your "cryptographic standard library". We support Python 2.6-2.7, Python 3.3+, and PyPy. Changelog: * Updated Windows and OS X wheels to be compiled against OpenSSL 1.0.2i. * Resolved a UserWarning when used with cffi 1.8.3. * Fixed a memory leak in name creation with X.509. * Added a workaround for old versions of setuptools. * Fixed an issue preventing cryptography from compiling against OpenSSL 1.0.2i. With version 1.5.1 we are still linking 1.0.2 for the Mac and Windows wheels, but in the 1.6 release we will switch to linking 1.1.0. Thanks to all the contributors for their help on this release! -Paul Kehrer (reaperhulk)
