示例1: sink

PublicKey::decode(CryptoPP::BufferedTransformation& in)
{
// SubjectPublicKeyInfo ::= SEQUENCE {
// algorithm AlgorithmIdentifier
// keybits BIT STRING }
using namespace CryptoPP;
try
{
std::string out;
StringSink sink(out);
////////////////////////
// part 1: copy as is //
////////////////////////
BERSequenceDecoder decoder(in);
{
assert(decoder.IsDefiniteLength());
DERSequenceEncoder encoder(sink);
decoder.TransferTo(encoder, decoder.RemainingLength());
encoder.MessageEnd();
}
decoder.MessageEnd();
////////////////////////
// part 2: check if the key is RSA (since it is the only supported for now)
////////////////////////
