问题 I am struggling to find a mechanism to send a request to the target server and when the socket has data to be read, pass the socket to another process for getting the data out. I came so far using epoll on Linux, to implement it to the point that i do the handshake, i send the request and the request arrives, then i pass the socket fd to another process for futher handling, i explicitly save the SSL Session using PEM_write_bio_SSL_SESSION and then read it using PEM_read_bio_SSL_SESSION and

问题 Consider the following code: fileHandle = open ( 'test8.pem','w' ) fileHandle.write (data) pub_key = M2Crypto.RSA.load_pub_key(open('test8.pem')) Which produces the following error: File "/usr/lib/python2.4/site-packages/M2Crypto/RSA.py", line 343, in load_pub_key bio = BIO.openfile(file) File "/usr/lib/python2.4/site-packages/M2Crypto/BIO.py", line 186, in openfile return File(open(filename, mode)) IOError: [Errno 2] No such file or directory: '' How do I pass the file into load_pub_key

问题 I try to install M2Crypto, but I can't install it, the error I have is the following: I am in a virtual miniconda environment. building 'M2Crypto._m2crypto' extension gcc -pthread -B /home/lcteen/miniconda3/envs/django/compiler_compat -Wl,--sysroot=/ -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/home/lcteen/miniconda3/envs/django/include/python3.7m -I/home/lcteen/Downloads/M2Crypto-0.35.2/SWIG -c SWIG/_m2crypto_wrap.c -o build/temp.linux-x86_64-3.7/SWIG/_m2crypto

问题 I have a working test of a hardware device that uses RSA encryption, in Python using M2Crypto. Now I need to test a similar device that uses 3DES encryption. But I can't figure out how to use M2Crypto to do triple DES encryption. I know it should be possible from this chart. But unfortunately the documentation of M2Crypto I've found is sketchy. (The homepage at http://chandlerproject.org/ seems to be gone, along with Chandler.) I've searched for 3DES and "OpenSSL API" and found some hard to

问题 I have a pair of ECDSA keys and using the following code, I am trying to compare the signatures for a 'hello' string computed using OpenSSL and M2Crypto library in python. Here is the code: import subprocess from hashlib import sha256 public_key_filename = 'ca_pu.pem' private_key_filename = 'ca_pr.pem' signature_filename = 'signature' sigoutput = open(signature_filename, 'w') cmd = 'openssl dgst -sha256 -sign'.split() cmd.append(private_key_filename) p = subprocess.Popen(cmd, stdin=subprocess

问题 I spent hours now and I can not find my error. I want a simple routine that creates a S/MIME signed message that could be used with smtplib later. This is, what I have so far: #!/usr/bin/python2.7 # -*- coding: utf-8 -*- from __future__ import print_function from __future__ import absolute_import import sys from M2Crypto import BIO, Rand, SMIME text = """Das ist ein einfacher Satz""" sign_cert = "cert.pem" sign_key = "key.pem" # ----------------------------------------------------------------

问题 this works perfectly in command-line, I would like to do the same using M2Crypto in Python code. openssl crl2pkcs7 -nocrl -certfile ra.crt -out ra-ca.p7b -certfile ca.crt. 回答1: Checkout the below link. This will help you.

问题 I am migrating a service from Python 2.7 to Python 3.5 which communicated with another service using RSA encryption/decryption. Python(v2.7) m2crypto(0.25.1) < Correct Signature > key = M2Crypto.RSA.load_key(private_key) digest = hashlib.sha1(bytes(cipher_text, encoding="UTF-8")).hexdigest() signature = hexlify(key.private_encrypt(digest, M2Crypto.RSA.pkcs1_padding)) Python(v3.5) rsa(v3.4.2) pri_key = rsa.PrivateKey.load_pkcs1(private_key) signature = hexlify(rsa.sign(cipher_text.encode(),
