I probably should have given you this, too. It uses ECIES<ECP> rather than
the private key.
string encoded =
"MIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0wawIBAQQgCPSuFr4iSIaQprjj"
"chHPyDu2NXFe0vDBoTpPkYaK9dehRANCAATnaFz/vQKuO90pxsINyVNWojabHfbx"
"9qIJ6uD7Q7ZSxmtyo/Ez3/o2kDT8g0pIdyVIYktCsq65VoQIDWSh2Bdm";
int main(int argc, char* argv[])
{
try
{
string decoded;
StringSource ss1(encoded.c_str(), true, new Base64Decoder(new
StringSink(decoded)));
ECIES<ECP>::Decryptor decryptor;
decryptor.AccessKey().Load(StringStore((const byte*)decoded.data(),
decoded.size()).Ref());
// AccessKey() provides a non-const reference
AutoSeededRandomPool prng;
decryptor.GetKey().ThrowIfInvalid(prng, 3);
// GetKey() provides a const reference
cout << "Private key appears to be valid" << endl;
}
catch(Exception& ex)
{
cerr << ex.what() << endl;
return 1;
}
return 0;
}
It produces the same result:
$ ./test.exe
Private key appears to be valid
