问题 I want to be able to pass a certificate to Python's ssl library without requiring a temporary file. It seems that the Python ssl module cannot do that. To work around this problem I want to retrieve the underlying SSL_CTX struct stored in the ssl._ssl._SSLContext class from the native _ssl module. Using ctypes I could then manually call the respective SSL_CTX_* functions from libssl with that context. How to do that in C is shown here and I would do the same thing via ctypes. Unfortunately, I

问题 I've created a key pair using the following code in python with pyOpenSSL: from OpenSSL import crypto k = crypto.PKey() k.generate_key(crypto.TYPE_RSA, 2048) Now how can I create the private and public key .pem files from the key object? If there is any tutorial available please let me know. I found none. From the manual, it's difficult to know as I'm new to OpenSSL. What are the chances that the same code will create two same key pairs is there is no specific unique key is being used in RSA?

问题 I get this error whenever I try to install any module using pip, but easy_install work perfectly. I have no proxies configured in my Ubuntu 12.04 machine. Previously it was working fine, just dnt know, how it stoped working suddenly. This is error i get, while running sudo pip install <any_package_name> : Exception: Traceback (most recent call last): File "/tmp/tmpOA61D3/pip.zip/pip/basecommand.py", line 246, in main status = self.run(options, args) File "/tmp/tmpOA61D3/pip.zip/pip/commands

问题 I need to get a detached PKCS #7 signature of some string in Python, using PyOpenSSL. I've got a key in .p12 file. So far, I'm trying to do so: from OpenSSL.crypto import load_pkcs12, sign pkcs12 = load_pkcs12(key_dat, key_pwd) algo = pkcs12.get_certificate().get_signature_algorithm() pkey = pkcs12.get_privatekey() sg = sign(pkey, manifest, algo) But it's not what required. I've searched net, but most examples are related to signing email chunks and use M2Crypto. Is there any way of doing it

问题 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

问题 how does openssl works with key as it is taking any size of key (1 byte to any size). What is the procedure to go to actual key here .. openssl enc -d -des-ecb -in cipher.txt -out text.out -K '530343412312345445123345677812345678812324' 回答1: how does openssl works with key ... What is the procedure... It depends on the program, but procedures are usually consistent across the library. In you example, you are using the openssl dec , so you are using the dec sub-program. The source code is

问题 I am using Titanium 3.0 and trying to update pyOpenSSL. I have checked the python website and only see downloadable links for Windows. In the Tianium forum they say that "If you installed Python using MacPorts or Homebrew, use the same utility to install PyOpenSSL and PyCrypto." I tried using homebrew and did "brew install pyopenssl" and got the error message "No available formula for pyopenssl". Any advice? 回答1: try using easy_install easy_install PyOpenSSL easy_install PyCrypto 回答2: Install
