CryptoPP::AutoSeededRandomPool rng;
int main() {
CryptoPP::RSA::PrivateKey private_key;
private_key.GenerateRandomWithKeySize(rng, 2048);
std::string base64_private_key;
CryptoPP::Base64Encoder private_key_sink(new
CryptoPP::StringSink(base64_private_key));
private_key.Save(private_key_sink);
CryptoPP::ArraySource as((const byte *)base64_private_key.data(),
base64_private_key.size(), true, new CryptoPP::Base64Decoder());
private_key.Load(as);
return 0;
}
Compiling and running with the following command occasionally fails with a
decoding error
g++ save_then_load.cc -lcrypto++ && ./a.out
Error:
terminate called after throwing an instance of 'CryptoPP::BERDecodeErr'
what(): BER decode error
Aborted (core dumped)
Are there any caveats in those Load and Save function that I am missing?
