Hello,
I am trying to run a very simple stream cipher example, taken from the
FAQ, but I am getting a segmentation fault.
Here is the code:
#include <sosemanuk.h>
using CryptoPP::Sosemanuk;
int main()
{
byte plaintext[100], ciphertext[100],
key[Sosemanuk::DEFAULT_KEYLENGTH], iv[Sosemanuk::IV_LENGTH];
// put data into key, iv, and plaintext here
// encrypt
Sosemanuk::Encryption enc(key, Sosemanuk::DEFAULT_KEYLENGTH, iv);
enc.ProcessData(ciphertext, plaintext, 100);
// now decrypt
Sosemanuk::Decryption dec(key, Sosemanuk::DEFAULT_KEYLENGTH, iv);
dec.ProcessData(plaintext, ciphertext, 100);
}
My compiler in MinGW g++ 4.5.0, OS is Windows XP 64-bit edition
Service Pack 2.
CryptoPP version is 5.6.0.
gdb gives this strack trace:
Program received signal SIGSEGV, Segmentation fault.
#0 0x00409da8 in CryptoPP::SosemanukPolicy::OperateKeystream
(this=0x46a190, operation=2293488,output=0x77bbcbb5 "ï≡ï╞ΦA╣",
input=0x3f0000 "╚", iterationCount=0) at sosemanuk.cpp:605
#1 0x003f23e0 in ?? ()
Cannot access memory at address 0x50000065
What am I doing wrong?
Thanks,
Nate.
