问题 The Problem While I run you python3 application, it shows File "/usr/local/lib/python3.6/ssl.py", line 101, in <module> import _ssl # if we can't import it, let the error propagate ModuleNotFoundError: No module named '_ssl' What I've tried install the dependencies yum install openssl-devel I also edited the setup.py file and recomplie python3 # Detect SSL support for the socket module (via _ssl) search_for_ssl_incs_in = [ '/usr/local/ssl/include', '/usr/local/include/openssl', #I've added

问题 I'm now developing a chatting server in Python. I am in the middle of applying pyOpenSSL to the chatting server and dummy clients which I made for testing. But whenever sending text messages and photo file from dummy clients to the server, pyOpenSSL returns significant error which drives me to stop using pyOpenSSL like below. send_text_message() : exception : [Errno 1] _ssl.c:1309: error:1409F07F:SSL routines:SSL3_WRITE_PENDING:bad write retry send_text_message() : exception : [Errno 1] _ssl

问题 I'm writing an app that requires a cert to be installed in the client browser. I've found this in the PyOpenSSL docs for the "Context" object but I can't see anything about how the callback is supposed to validate the cert, only that it should, somehow. set_verify(mode, callback) Set the verification flags for this Context object to mode and specify that callback should be used for verification callbacks. mode should be one of VERIFY_NONE and VERIFY_PEER. If VERIFY_PEER is used, mode can be

问题 I want to verify the downloaded file's signature and cert using pyopenssl, but the documentation is not clear and Google is of no help. I have a root CA cert in user's machine, now when user download the file then I will send a certificate and signature along with it. First I need to verify the certificate with rootCA on machine then I need to verify the signature with file In openssl I can use following to verify the ca cert openssl verify -CAfile <root_pem> <cert_pem> and following to

问题 I'm trying to create a non-detached signature on python3. I currently have code that does this on python2 with m2crypto, but m2crypto isn't available for python3. I've been trying rsa, pycrypto and openssl, but haven't seen to find how. Here's the equivalent OpenSSL command: openssl smime -sign -signer $CRTFILE -inkey $KEYFILE -outformDER -nodetach It's the nodetach option that I can't imitate with either rsa, pyopenssl or pycrypto. Has anyone does this on python3? I'd like to avoid using

问题 I can sign and verify data in PHP using OpenSSL: function generate_signature($privateKey, $data) { $keyData = openssl_get_privatekey($privateKey); openssl_sign($data, $signature, $keyData, OPENSSL_ALGO_SHA256); openssl_free_key($keyData); $sigText = base64_encode($signature); return $sigText; } function verify_signature($pubKey, $sigText, $data) { $signature = base64_decode($sigText); $keyData = openssl_get_publickey($pubKey); $ok = openssl_verify($data, $signature, $keyData,

问题 I get lot of pdfs in my system. I need to check if all of these files are:- digitally signed their integrity maintained(by comparing the hash of file content with the message digest embedded in /Contents. . I am using python to do this. Till now I have been able to get the /Content from signature dictionary using PyPDF2. The content is pkcs7--der encoded. Is there a way I can extract the signed message digest? Similar operation was done in C as this answer 回答1: DER is binary format, its

问题 I am trying to connect to snowflake from python. It's very simple straight forward, but unfortunately I'm unable to succeed. Same piece of code works in other machines (when my friends tested). Not sure what dependencies I'm missing. Tried debugging very hard, even tried with pipenv (assuming python path must be conflict) but no luck. I kindly request you to help and resolve this issue. Summarising below steps what i have done. sudo -H pip install pipenv #installed pipenv mkdir -p test_vn

问题 I'm trying to extract the private key and certificate from a PKCS12 file using pyOpenSSL, and am having a hard time figuring out how to convert the data to PEM-encoded strings. The question below implies that it's possible, but I haven't been able to figure it out. Python: reading a pkcs12 certificate with pyOpenSSL.crypto 回答1: Give a look on the dump_certificate, dump_certificate_request, dump_privatekey methods: http://pyopenssl.sourceforge.net/pyOpenSSL.html/openssl-crypto.html 来源： https:/

问题 I'm trying to load a private key using OpenSSL with: from OpenSSL import crypto PRIVATE_KEY = 'private_key.pem' with open(PRIVATE_KEY, 'rb') as fh: private_key = crypto.load_privatekey(crypto.FILETYPE_PEM, fh.read(), '') But I'm receiving this unhelpful error: Traceback (most recent call last): File "keytest.py", line 5, in <module> private_key = crypto.load_privatekey(crypto.FILETYPE_PEM, fh.read(), '') File "/usr/local/lib/python2.7/dist-packages/OpenSSL/crypto.py", line 2010, in load
