Originalnachricht

Name        : python-crypto
Product : Fedora 18
Version : 2.6.1
Release : 1.fc18
URL : http://www.pycrypto.org/
Summary : Cryptography library for Python
Description :
PyCrypto is a collection of both secure hash functions (such as MD5 and
SHA), and various encryption algorithms (AES, DES, RSA, ElGamal, etc.).

-------------------------------------------------------------------------------

Update Information:

In previous versions of PyCrypto, the Crypto.Random PRNG exhibits a race
condition that may cause forked processes to generate identical sequences of 'random' numbers.

This release fixes the problem by resetting the rate-limiter when
Crypto.Random.atfork() is invoked.
