python - How to use latest openssl library with pyOpenSSL? -

-

i using pyopenssl, , uses openssl 1.0.1f installed system. install openssl 1.0.1j source, , set new version library path ld_library_path, @ time, when running py file, produce error:

file "sslcert.py", line 5, in <module> openssl import ssl, _util, crypto ...  file "/usr/local/lib/python2.7/dist-packages/cffi-0.8.6-py2.7-linux-x86_64.egg/cffi/vengine_cpy.py", line 149, in load_library     raise ffiplatform.verificationerror(error) cffi.ffiplatform.verificationerror:   importing '/usr/local/lib/python2.7/dist-packages/cryptography-0.6.1-py2.7-linux-x86_64.egg/cryptography/_cryptography_cffi_36a40ff0x2bad1bae.so':     /usr/local/lib/python2.7/dist-packages/cryptography-0.6.1-py2.7-linux-x86_64.egg/cryptography/_cryptography_cffi_36a40ff0x2bad1bae.so:   symbol ec_gfp_nistp521_method, version openssl_1.0.1 not defined in file libcrypto.so.1.0.0 link time reference

i wonder using latest openssl library pyopenssl, how can fix issue?

you need recompile cryptography against newer version of openssl.

make sure install development headers openssl , rebuild (perhaps re-installing) cryptography.

you may want investigate use of virtualenv keep newly built versions separate installed versions.
