pycrypto

I have a RSA public key in PEM format + PKCS#1(I guess): -----BEGIN RSA PUBLIC KEY----- MIGJAoGBAJNrHWRFgWLqgzSmLBq2G89exgi/Jk1NWhbFB9gHc9MLORmP3BOCJS9k onzT/+Dk1hdZf00JGgZeuJGoXK9PX3CIKQKRQRHpi5e1vmOCrmHN5VMOxGO4d+zn JDEbNHODZR4HzsSdpQ9SGMSx7raJJedEIbr0IP6DgnWgiA7R1mUdAgMBAAE= -----END RSA PUBLIC KEY----- I want to get the SHA1 digest of its ASN1 encoded version in Python. The first step should be to read this key, but I failed to do it in PyCrypto: >> from Crypto.PublicKey import RSA >> RSA.importKey(my_key) ValueError: RSA key format is not supported The documentation of PyCrypto says PEM +

I need help using RSA encryption and decryption in Python. I am creating a private/public key pair, encrypting a message with keys and writing message to a file. Then I am reading ciphertext from file and decrypting text using key. I am having trouble with the decryption portion. As you can see in my code below, when I put in decrypted = key.decrypt(message) that the program works, yet the decrypted message is encrypted again. It seems like it is not reading the ciphertext from the file. Can anyone help me write this code so decryption reads ciphertext from file and then uses key to decrypt

I am trying to familiarize myself with the pycrypto module, but the lack of clear documentation makes things difficult. To start with, I would like to understand signing and verifying data. Could someone please provide an example for how this would be written? This is a fleshed-out version of the example in the documentation: import Crypto.Hash.MD5 as MD5 import Crypto.PublicKey.RSA as RSA import Crypto.PublicKey.DSA as DSA import Crypto.PublicKey.ElGamal as ElGamal import Crypto.Util.number as CUN import os plaintext = 'The rain in Spain falls mainly on the Plain' # Here is a hash of the

I am attempting to install pycrypto (version 2.3) on OS X via pip. I am getting a "Broken pipe" error when the compiler attempts to compile MD2.c. I get a very similar error when using easy_install. Here is the error that I am getting: bash-3.2$ bash-3.2$ sudo pip install pycrypto Password: Downloading/unpacking pycrypto Running setup.py egg_info for package pycrypto Installing collected packages: pycrypto Running setup.py install for pycrypto warning: GMP library not found; Not building Crypto.PublicKey._fastmath. building 'Crypto.Hash.MD2' extension gcc-4.2 -fno-strict-aliasing -fno-common

I just found pycrypto today, and I've been working on my AES encryption class. Unfortunately it only half-works. self.h.md5 outputs md5 hash in hex format, and is 32byte. This is the output. It seems to decrypt the message, but it puts random characters after decryption, in this case \n\n\n... I think I have a problem with block size of self.data, anyone know how to fix this?
