Does anyone have any idea why the derived key is different. I believe I'm
doing this correctly, but please do point out my mistake
C++
/* 256bit key */
string key = "Y1Mjycd0+O+AendY5pB58JMlmS0EmBWgjdj2r2KW6qQ=";
string decodedKey;StringSource(key, true, new Base64Decoder(new
StringSink(decodedKey)));const byte* keyByte = (const byte*) decodedKey.data();
/* Generate IV *//*
AutoSeededRandomPool prng;
byte iv[AES::BLOCKSIZE];
prng.GenerateBlock(iv, sizeof(iv));
*/
/* FOR TESTING PURPOSES, HARDCODE IV */
string iv = "5iFv54dCRq5icQbD7QHQzg==";
string decodedIv;StringSource(iv, true, new Base64Decoder(new
StringSink(decodedIv)));const byte* ivByte = (const byte *) decodedIv.data();
byte derivedKey[32];
PKCS5_PBKDF2_HMAC<CryptoPP::SHA1> pbkdf2;
pbkdf2.DeriveKey(derivedKey, 32, 0, keyByte, 32, ivByte, 16, 100);
/*
* derivedKey: 9tRyXCoQLTbUOLqm3M4OPGT6N25g+o0K090fVp/hflk=
*/
Node-JavaScrit
var key = "Y1Mjycd0+O+AendY5pB58JMlmS0EmBWgjdj2r2KW6qQ=";
var iv = crypto.randomBytes(16);
iv = "5iFv54dCRq5icQbD7QHQzg=="; /* HARDCODE IV */
crypto.pbkdf2(key, iv, 100, 32, function(err, derivedKey) { }
/*
* derivedKey: dZqBpZKyUPKn8pU4pyyeAw7Rg8uYd6yyj3WI1MIJSyc=
