Re: BERDecode throw (was: ... exporting public RSA key to std::string)

[Jeffrey Walton]

No Joy here either:

CryptoPP::HexDecoder decoder;
decoder.Attach( new CryptoPP::StringSource( prvkey, true ) );
temp1.AccessKey().Load( decoder );

std::cout << "Dumping Public Key..." << std::endl;
DumpPublicKey( temp1 );

Hi Wei,

Here are the details... b = '3': This is the first byte of the string or file.

// asn.cpp
void BERGeneralDecoder::Init(byte asnTag)
    byte b;
    if (!m_inQueue.Get(b) || b != asnTag)
       BERDecodeError(); <=== Blow Up, b = '3', asnTag = '0'

    if (!BERLengthDecode(m_inQueue, m_length, m_definiteLength))
       BERDecodeError();

m_length = 14757... (20 decimal digits)
m_definiteLength = true
