Hi,
I tried using SapphireRNG (sapphire.h) in Crypto++ 5.0.4 FIPS dll with
the non-FIPS algo lib with MSVC++ 6.0 SP6 but apparently I am missing
the implementation for the RandomNumberGenerator class's pure virtual
functions?
Im just doing :
#include "dll.h"
#include "sapphire.h"
CryptoPP::SapphireRNG myRNG(myBlob.pbData, myBlob.cbData);
It gives the compiler error "Cannot instantiate abstract base class
due to following members" then lists some of the methods such as
GenerateByte() in RandomNumberGenerator...
My question is : Using Crypto++ 5.0.4 API how can I get the same
sequence of ('predictable') random numbers given the same input seed
as a varying-length byte array?
Which class should I use? LC_RNG takes a word32 as seed but I need a
varying length byte array as seed.
Actually what I am trying to do (and my real task) in a function, lets
say its called DeriveRSAKeyPairFromByteArray(...), is 'repeatedly and
reproducably' generate the same 1024-bit RSA keypair for the same
given byte array as input.
So I am trying to provide a 'predictable' RNG to the
InvertibleRSAFunction (PrivateKey) method
GenerateRandomWithKeySize(...) and I came across the compile problem
mentioned above...
Thanks,
Vishal
