Hi Folks, I have a C++ class that is generating a random number using cryptopp, using either almost exactly the same code as per the FAQ.
I also have a test harness that creates and destroys the class, as it applies different testcases to it. The second time the class is created and the random number generation fn is entered, cryptopp crashes. The code snippets I have are shown below: /* // Autoseeded random pool object creates a pool of random numbers to // read from, already seeded with a seed created from one of: // - CryptGenRandom() by way of a Cryptographic Service Provider // - /dev/random // - /dev/urandom */ CryptoPP::AutoSeededRandomPool rand_num_gen; rand_num_gen.GenerateBlock(plainstring, size); Alternately: // Alternate method: // Declare a random number generator object. OFB_Mode<AES>::Encryption s_globalRNG; // Init the random generator with a seed based on current time. std::string seed = IntToString(time(NULL)); seed.resize(16); s_globalRNG.SetKeyWithIV((byte *)seed.data(), 16, (byte *)seed.data()); // Use the random generator to generate a random string. s_globalRNG.GenerateBlock((byte *)plainstring, size); Either way, I get a crash. Has anyone seen this before, or have a suggestion? cheers Nick -- You received this message because you are subscribed to the "Crypto++ Users" Google Group.
