m2crypto

Can someone please point out mistakes in this code: __author__="gaurav" __date__ ="$15 Feb, 2011 5:10:59 PM$" import M2Crypto from base64 import b64encode, b64decode ENC=1 DEC=0 def AES_build_cipher(key, iv, op=ENC): """""""" return M2Crypto.EVP.Cipher(alg='aes_128_cbc', key=key, iv=iv, op=op) def AES_encryptor(key,msg, iv=None): """""" #Decode the key and iv key = b64decode(key) if iv is None: iv = '\0' * 16 else: iv = b64decode(iv) # Return the encryption function def encrypt(data): cipher = AES_build_cipher(key, iv, ENC) v = cipher.update(data) v = v + cipher.final() del cipher v =

I have a file with the public exponent and modulus in it. They're not in pem or xml or der format, they're just the values written in at their offsets. How can I make a public key out of them with M2Crypto? I also have the private key in the same format. I've managed to use code that someone posted here on Stackoverflow to generate a PEM file with php, but this seems like an extremely ridiculous way to do it. This isn't a one-time thing either, I need to be able to read the public exponent and modulus from files in this format to check the signature. mowwwalker Thank you very much to Lars here

I am using M2Crypto-0.20.2. I want to use engine_pkcs11 from the OpenSC project and the Aladdin PKI client for token based authentication making xmlrpc calls over ssl. from M2Crypto import Engine Engine.load_dynamic() dynamic = Engine.Engine('dynamic') # Load the engine_pkcs from the OpenSC project dynamic.ctrl_cmd_string("SO_PATH", "/usr/local/ssl/lib/engines/engine_pkcs11.so") Engine.cleanup() Engine.load_dynamic() # Load the Aladdin PKI Client aladdin = Engine.Engine('dynamic') aladdin.ctrl_cmd_string("SO_PATH", "/usr/lib/libeTPkcs11.so") key = aladdin.load_private_key("PIN","password")

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 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 add it to the context but i can not read the ssl socket in another process because i get either Internal
