pyopenssl

I'm trying to implement the answer found at Python Paste SSL server with TLSv1.2 and Forward Secrecy . How do I use context.set_tmp_ecdh()? That method is not defined on either my Linux or Windows machines. It is in the pyOpenSSL docs, and various examples I've seen. I'm using Python 2.6.6 (or 2.7) and pyOpenSSL v 0.13 (specifically CentOS package pyOpenSSL-0.13.1-2.el6.x86_64.rpm). Is there a specific version or additional dependency, etc. that I'm missing? Support for ecdh was added in pyOpenSSL 0.15, so you can't use it with your installed version of pyOpenSSL. You'll have to install a

I would like to parse android apk's CERT.RSA in Python. I know it can be parsed with pyOpenSSL import OpenSSL cert = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_ASN1, open('CERT.RSA', 'rb').read()) cert = OpenSSL.crypto.load_pkcs7_data(type, buffer) cert is of type 'OpenSSL.crypto.PKCS7'. BUT right now PKCS7 object is not complete, I cannot get attributes I need, is there any alternative way to parse that file? Comments : I don't know if there's a way to convert it to another format so it can be parsed You can convert PKCS#7 to PEM using openssl , PEM is readable using PyOpenSSL

I have application test.c which by using gcc on host(on ubuntu) machine i have succeed in compilation and successfully ran the application program on host. now I would like to cross compile the same application with arm-cross compiler for LPC1788 . please guide me how to link the openssl library files My Mkakefile with GCC CC = gcc CFLAGS = -D__XMLSEC_FUNCTION__=__FUNCTION__ -DXMLSEC_NO_XKMS=1 -DXMLSEC_NO_CRYPTO_DYNAMIC_LOADING=1 -I/usr/include/xmlsec1 -I/usr/include/libxml2 -DXMLSEC_OPENSSL_097=1 -DXMLSEC_CRYPTO_OPENSSL=1 -DXMLSEC_CRYPTO=\"openssl\ -DUNIX_SOCKETS -D XML_SECURITY LDFLAGS =

During the scraping process using scrapy one error appears in my logs from time to time. It doesnt seem to be anywhere in my code, and looks like it something inside twisted\openssl. Any ideas what caused this and how to get rid of it? Stacktrace here: [Launcher,27487/stderr] Error during info_callback Traceback (most recent call last): File "/opt/webapps/link_crawler/lib/python2.7/site-packages/twisted/protocols/tls.py", line 415, in dataReceived self._write(bytes) File "/opt/webapps/link_crawler/lib/python2.7/site-packages/twisted/protocols/tls.py", line 554, in _write sent = self.

I want to send a certificate from a "certificate authority" to a node through sockets. I have a certificate created using this example https://skippylovesmalorie.wordpress.com/2010/02/12/how-to-generate-a-self-signed-certificate-using-pyopenssl/ How would I convert this into a .pem file so I can send it as a string through a socket and then convert it on the other end back into a .pem and use get_certificate to extract this certificate from it. Python: reading a pkcs12 certificate with pyOpenSSL.crypto Its probably a hacky way to do it, but I want to simplify it for myself. (or not) I'm

I am new to python and still learning it so my question can be little naive. Please bear with it ;) The problem is client will be sending CSR and I want to sign it with my CA root certificate and return the signed certificate back to client. I have been using this command to do it using command line openssl x509 -req -in device.csr -CA root.pem -CAkey root.key -CAcreateserial -out device.crt -days 500 same thing I want achieve using python. I have come across python library for openssl pyopenssl is it possible using this library ? How ? or shoudl I go for M2Crypto ? You can indeed go with

I need to install OpenSSL on my python2.7.
