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 verify the file openssl dgst <algo> -verify <cert_pub_key> -signature <signature> <file> I am looking for

This is for a homework assignment! I get the server's certificate using get_peer_certificate() and the calling dump_certificate to dump the certificate in a variable. The format is PEM and looks right to me. -----BEGIN CERTIFICATE----- GIBBERISH................ ...................... ........................ -----END CERTIFICATE----- How do I extract the server's public key from this file ('server.pubkey') and encrypt plaintext using RSA algorithm and any python library. At the time of writing this, I am using pyOpenSSL I'd recommend using a more broad crypto library such as M2Crypto which has

I have got an API that I have to work with. The API is secured by HTTPS and uses mutual authentication/client certificates. I have a PEM file and a CRT file. When I connect to the server regularly, using PyOpenSSL I have no problem, here is the code: import settings from OpenSSL import SSL import socket def verify(conn, cert, errnum, depth, ok): # This obviously has to be updated print 'Got certificate: %s' % cert.get_subject() return ok def password_callback(maxlen, verify, extra): print (maxlen, verify, extra) return settings.DEPOSIT_CODE context = SSL.Context(SSL.SSLv23_METHOD) context.set

Any idea about what cause the error below ?

How can I block SSL protocols in PyOpenSSL in favour of TLS ? I'm using CentOS 7 and have these versions: pyOpenSSL-0.13.1-3.el7.x86_64 openssl-1.0.1e-34.el7_0.7.x86_64 In my config file (this if for a CherryPy app) I have: 'server.ssl_module': 'pyopenssl', This is really good question for CherryPy today. This month we started discussing SSL issues and overall maintainability of CherryPy's wrappers over py2.6+ ssl and pyOpenSSL in CherryPy user group . I'm planning a topic about SSL issues there, so you can subscribe for the group to get more details later. For now, here's what is possible. I
