Hello Everyone,
Could someone do me a favor to help it out?
With my 64bit Window7 machine,
I can build Crypto++ static library in X86 in visual studio 2017, and use
it without any issue,
so I built Crypto++ static library in X64 within visual studio 2017, and
tried to use it with 64bit application,
It always crashed on the line m_k[i] = a+b with error message :
System.AccessViolationException: 'Attempted to read or write protected
memory. This is often an indication that other memory is corrupt.'
Below is the section of codes when crashed, the Crypto++ is the latest
source.2016.
void Twofish::Base::UncheckedSetKey(const byte *userKey, unsigned int
keylength, const NameValuePairs &)
{
AssertValidKeyLength(keylength);
unsigned int len = (keylength <= 16 ? 2 : (keylength <= 24 ? 3 : 4));
SecBlock<word32> key(len*2);
GetUserKey(LITTLE_ENDIAN_ORDER, key.begin(), len*2, userKey, keylength);
unsigned int i;
for (i=0; i<40; i+=2)
{
word32 a = h(i, key, len);
word32 b = rotlFixed(h(i+1, key+1, len), 8);
m_k[i] = a+b;
m_k[i+1] = rotlFixed(a+2*b, 9);
}
.............................................................
Did I miss any setting?
Thanks so much for any help.
Kevin
