pyopenssl

问题 I have python 3.3 working and can run some basic code (like print("Hello World") ). Next I need so get PyOpenSSL set up. I've downloaded and unzipped the pyOpenSSL-master.zip from their github site, but I have no idea what to do with it next. I moved the unzipped directory into /libs , cd into /libs/pyopenssl-master and did python setup.py install --user . But that failed with /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'setup

问题 I have the following code which works perfectly for signing strings. However, I now need to programatically sign and get a signature for a file in the same way as I would using OpenSSL on the commandline e.g. openssl dgst -sha1 –sign key.pem -out sig1 file.tar . import OpenSSL from OpenSSL import crypto import base64 key_file = open("key.pem", "r") key = key_file.read() key_file.close() password = "password" if key.startswith('-----BEGIN '): pkey = crypto.load_privatekey(crypto.FILETYPE_PEM,

问题 I tried installing M2Crypto and facing problems. I don't want to force my customers to use such libraries which are difficult to install. So, I thought I would give pyOpenSSL a try. I am able to get the public key from pem certificate but am not able to find any way to verify the signature. 回答1: You simply can't do this with pyOpenSSL. It is a very limited wrapper around openssl library. But I have a guess what's wrong with building M2Crypto on your host. Try running: export SWIG_FEATURES=-I

问题 Question How can I verify that an X.509 certificate is signed by another certificate using PyOpenSSL or Twisted? I want a client to verify that the received server certificate is the one that signed its client certificate. I've looked through the PyOpenSSL documentation and can't seem to find anything on how to verify a certificate separately from the establishing the SSL connection. I found a reference to OpenSSL.crypto:X509.verify() in twisted.internet._sslverify:PublicKey.verifyCertificate

问题 I know this might be due to lack of better knowledge, but I seem not to be able to get this running. What is the right way as of today how to create the correct certificates / pem files for PyAPN ? There are so many instructions at different dates that report different approaches - I am confused. I exported the Apple push certificate and the private key into cert.p12 and key.p12 respectively on my mac. Then I ran the commands below and uploaded them to my server. openssl pkcs12 -nocerts -out

问题 I'm using Ubuntu 14.04. I was trying to install pyopenssl on my machine. However it always fail with this info. I searched it on the google but didn't find any solution: gcc -pthread -shared /tmp/pip_build_pi314/cryptography/cryptography/hazmat/bindings/__pycache__/cryptography/hazmat/bindings/__pycache__/_Cryptography_cffi_79a5b0a3x3a8a382.o -L/home/pi314/anaconda/lib -lcrypto -lssl -lpython2.7 -o /tmp/pip_build_pi314/cryptography/cryptography/hazmat/bindings/__pycache__/_Cryptography_cffi

问题 I have Ubuntu 16.04 . It has OpenSSL 1.0.2g . I need to use OpenSSL 1.1.0g . Note that OpenSSL 1.1.0g is installed in my other machine Ubuntu 18 . But I need to run a python program in Ubuntu 16.04 but I need the specific OpenSSL 1.1.0g . I did: sudo apt-get upgrade sudo apt-get update But OpenSSL in my Ubuntu machine did not get updated. How can I update it? I use python socket, ssl modules to make TLS connection in port 443. Will python automatically recognizes OpenSSL 1.1.0g if I updated

问题 I was working with Steffen Ullrich on a previous issue, and now it is morphing into a new issue. So taking his advice (thank you Steffen), I am posting a separate question: $ python -c 'import ssl; print ssl.OPENSSL_VERSION' OpenSSL 0.9.8zh 14 Jan 2016 I have attempted just about everything under the sun (so it feels) to fix it. $ brew install openssl Warning: openssl 1.0.21 is already installed So I have both, but it only reads/links to OpenSSL 0.9.8zh? I am new to Python/Homebrew on my Mac.

问题 I am trying this bit of code. import pandas as pd fiddy_states=pd.read_html('https://simple.wikipedia.org/wiki/List_of_U.S._states') print(fiddy_states[0]) I am getting following error: Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/urllib/request.py", line 1318, in do_open encode_chunked=req.has_header('Transfer-encoding')) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 1239, in request

问题 I'm getting an error when connecting to www.mydomain.com using Python 2.7.12, on a fairly new machine that uses Windows 8.1. The error is SSL: CERTIFICATE_VERIFY_FAILED on the ssl_sock.connect line of the code below. The code wraps an SSL connection in an context, and specifies I don't want to carry out certificate verification: ssl._create_default_https_context = ssl._create_unverified_context s_ = socket.socket(socket.AF_INET, socket.SOCK_STREAM) context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
