I am beginner and sorry if this is a stupid question. I used templates in my code which i think are free. Can this be because they are not actually free or what?

It is totally free to use.

But when I try to write a file.png with the raw bytes, it doesn't write anything and the created png is blank. Any ideas how can I work around this?
size_t szDecodedLength = 0;
unsigned char * stDecodedQR = base64_decode(encodedPictureBase64,inLenEncodedPicture, &szDecodedLength);
ofstream outPicture("./flash/file.png", std::ios::out | std::ios::binary | std::ios::trunc);
string outString(reinterpret_cast<char*>(stDecodedQR), szDecodedLength);
if( outPicture && !outPicture.is_open() ){
return;
}
outPicture.write( reinterpret_cast<char*> (stDecodedQR), szDecodedLength);
// outPicture << outString; I've also tried creating a string and doing this but result is the same.
outPicture.flush();
outPicture.close();
This code solves the issue, it looks like it might be permission on the device I'm working on. Tested below code in Visual Studio with C++ and it generates the wanted file(picture) correctly, is a QR code that I can scan with my smartphone.
size_t szDecodedLength = 0;
unsigned char* stDecodedQR = base64_decode(encodedPictureBase64, inLenEncodedPicture, &szDecodedLength);
const size_t szArr = szDecodedLength;
std::vector<unsigned char> vDecodedQR;
for (auto i = 0; i < szDecodedLength; i++) {
vDecodedQR.push_back(stDecodedQR[i]);
}
std::ofstream outPicture("mypng.png", std::ios::out | std::ios::binary | std::ios::trunc);
if (outPicture && !outPicture.is_open()) {
std::cerr << " Error creating PNG file" << std::endl;
return;
}
outPicture.write(reinterpret_cast<char*> (stDecodedQR), szDecodedLength);
outPicture.close();

How can I get the public exponent and modulus to encrypt my message from it?
since the 2000th years we were using a compression-lib called addCRYPT.dll from a company called littleBIGware for our Windows-apps. Lib and company doesn't exists anymore, but users of our apps created lots of files up to now which are compressed with this lib.
Now for a new version I don't want to use this old lib, but must still be able to decompress the existing data.
I tried Zip, GZip and some others, but with no success.
Does anybody now, how to decompress these data? Here is a hex-dump of the first 64 bytes of some compressed blocks. There is a kind of a pattern visible, but what?

I had to port a Java app to C++/Qt, but I have a problem about the RSA encryption.
Basically my app ask the server for a key and the the server return it like this :
30 81 9f 30 0d 06 09 2a 86 48 86 f7 0d 01 01 01 05 00 03
81 8d 00 30 81 89 02 81 81 00 b4 74 05 71 53 79 39 16 29
fc 17 d3 dd 27 c0 84 72 1e 4a 66 b8 43 e8 57 58 f6 13 65
3c a6 85 ff e1 c3 b3 76 11 3e 10 33 00 7d a4 ab 94 d3 86
a2 99 71 d6 c9 99 a6 54 ec 3c 32 de 25 60 61 c3 84 6d 00
32 6a 4e 7c f7 25 38 3c 12 f7 f7 c0 08 e0 8a ca 6f dc 1d
3c 37 bc e9 77 70 11 e7 9e 67 f0 96 d6 df a1 37 d2 8e 83
1c 75 cf 86 ff 39 bb 53 a6 63 f7 ce 99 eb b3 f2 20 39 37
52 41 31 6e 9f 02 03 01 00 01
After that, all i have to do is to encrypt the credentials and sending them to the server. But I can't find any way to use that key.
The Java version look like this
byte[] key;
// Get the key from the server
// ...
//
KeyFactory kf;
EncodedKeySpec eks = new X509EncodedKeySpec(key);
PublicKey localPublicKey = kf.generatePublic(eks);
I've looked both OpenSSL and QSsl libs but I didn't found anything like this.
If anyone had any ideas ...
I am looking for an example of LUC algorithm, but I can't find anything. I know that it is in Crypto++, but I don't know C++ too well to use it.
I look for an example of algorithm of LUC...
It kind of depends on what you want to do. You might want to browse luc.h to see some of the things Crypto++ offers for LUC. There's a LUCES, a LUCSS and a LUC_IES. The *ES is encryption scheme, the *SS is a signature scheme, and the *IES is an integrated encryption scheme (which includes a key agreement algorithm and mask function).
Generally speaking, LUC is a public key encryption system. Using it is like using any other public key encryption system offered by Crypto++. That's because all the public key encryption systems inherit from the same classes (more correctly, base interfaces). You can see the design in the comments for file pubkey.h.
$ grep -R LUCES *
...
typedef LUCES<OAEP<SHA> >::Decryptor LUCES_OAEP_SHA_Decryptor;
typedef LUCES<OAEP<SHA> >::Encryptor LUCES_OAEP_SHA_Encryptor;
And that's pretty much all you need, though you may not know it.
Here's the easier problem to solve. How do you perform RSA encryption in Crypto++?
$ grep -R RSAES *
...
typedef RSAES<PKCS1v15>::Decryptor RSAES_PKCS1v15_Decryptor;
typedef RSAES<PKCS1v15>::Encryptor RSAES_PKCS1v15_Encryptor;
typedef RSAES<OAEP<SHA> >::Decryptor RSAES_OAEP_SHA_Decryptor;
typedef RSAES<OAEP<SHA> >::Encryptor RSAES_OAEP_SHA_Encryptor;
If you find an RSAES_PKCS1v15_Decryptor or RSAES_OAEP_SHA_Decryptor example, you just copy/replace with LUCES_OAEP_SHA_Decryptor and it will work just fine. And if you find an RSAES_PKCS1v15_Encryptor or RSAES_OAEP_SHA_Encryptor example, you just copy/replace with LUCES_OAEP_SHA_Encryptor and it will work just fine.
You can find the examples of using RSAES_OAEP_SHA_Encryptor and RSAES_OAEP_SHA_Decryptor on the Crypto++ wiki page for RSA Encryption Schemes. Or you can use the ECIES examples at Elliptic Curve Integrated Encryption Scheme (remember, all the public key systems inherit from the same base interfaces, so they all have the same methods and you use them the same way).
This should get you started. It creates a private key, saves it, then creates a public key, and saves it.
try
{
AutoSeededRandomPool prng;
FileSink fs1("lucs-private.der", true);
FileSink fs2("lucs-public.der", true);
InvertibleLUCFunction params;
params.GenerateRandomWithKeySize(prng, 2048);
LUC::PrivateKey privateKey(params);
privateKey.DEREncode(fs1);
LUCES_OAEP_SHA_Decryptor decryptor(privateKey);
// ...
LUC::PublicKey publicKey(params);
publicKey.DEREncode(fs2);
LUCES_OAEP_SHA_Encryptor encryptor(publicKey);
// ...
}
catch(CryptoPP::Exception& ex)
{
cerr << ex.what() << endl;
}
If you don't want to use InvertibleLUCFunction, the do something like this to generate the key. Note: RSA has an InvertibleRSAFunction.
LUC::PrivateKey privateKey;
privateKey.Initialize(prng, 2048);
...
LUC::PublicKey publicKey(privateKey);
...
An here's yet another way to do it:
FileSink fs1("lucs-private.der", true);
FileSink fs2("lucs-public.der", true);
LUCES_OAEP_SHA_Decryptor decryptor;
decryptor.AccessKey().Initialize(prng, 2048);
decryptor.AccessKey().DEREncode(fs1);
...
LUCES_OAEP_SHA_Encryptor encryptor(decryptor);
encryptor.AccessKey().DEREncode(fs2);
...
And here's a dump of the private key created by the test program:
