Wow, after working for days, I post it on this group, but immediately
after I found a solution: I replaced strings with SecByteBlock.
Thanks for the time :-D
#include <crypto++/dll.h>
using namespace CryptoPP;
using namespace std;
int main(void)
{
AutoSeededRandomPool rng;
InvertibleRSAFunction parameters;
parameters.GenerateRandomWithKeySize(rng, 1536);
RSA::PrivateKey privateKey(parameters);
RSA::PublicKey publicKey(parameters);
RSAES_OAEP_SHA_Encryptor encryptor(publicKey);
RSAES_OAEP_SHA_Decryptor decryptor(privateKey);
static const int SIZE = 16;
SecByteBlock plaintext(SIZE);
byte block[SIZE];
rng.GenerateBlock(block, SIZE);
memcpy(plaintext, block, SIZE);
for(int x = 0; x < SIZE; x++) {
printf("%X%X", (block[x] & 240) >> 4, (block[x] & 15));
}
cout << endl;
size_t ecl = encryptor.CiphertextLength(plaintext.size());
SecByteBlock ciphertext(ecl);
encryptor.Encrypt(rng, plaintext, plaintext.size(), ciphertext);
size_t dpl = decryptor.MaxPlaintextLength(ciphertext.size());
SecByteBlock
recovered(decryptor.MaxPlaintextLength(ciphertext.size()));
DecodingResult result = decryptor.Decrypt(rng, ciphertext,
ciphertext.size(), recovered);
recovered.resize(result.messageLength);
assert(plaintext == recovered);
for(int x = 0; x < SIZE; x++) {
printf("%X%X", (plaintext[x] & 240) >> 4, (plaintext[x] & 15));
}
cout << endl;
return 0;
}
