Hi friends..
i'm really confused how to encrypt data using PrivateKey , NO Padding, and
Decrypt it using PublicKey.
Hmm, actually i can solve this problem easily using Java..
But i want implement the process in my C++ application..
*Snippet Code :*
byte[] inputEncryption =
ByteUtils.StringToHex("@ABCDEFGHIJKLMNO@ABCDEFGHIJKLMNO
@ABCDEFGHIJKLMNO@ABCDEFGHIJKLMNO");
//404142434445464748494A4B4C4D4E4F404142434445464748494A4B4C4D4E4F404142434445464748494A4B4C4D4E4F404142434445464748494A4B4C4D4E4F
Cipher rsaCipher2 = Cipher.getInstance("RSA/None/NoPadding");
RSAPublicKey myPubKEY = (RSAPublicKey)
KeyFactory.getInstance("RSA").generatePublic(rsaPublicKeySpec);
RSAPrivateKey myPrivKEY = (RSAPrivateKey)
KeyFactory.getInstance("RSA").generatePrivate(rsaPrivateKeySpec);
rsaCipher2.init(Cipher.ENCRYPT_MODE, myPrivKEY);
byte[] output = rsaCipher2.doFinal(inputEncryption);
System.out.println("OUTPUT Encryption = " +
ByteUtils.HexToString(output));
rsaCipher2.init(Cipher.DECRYPT_MODE, myPubKEY);
output = rsaCipher2.doFinal(output);
System.out.println("OUTPUT = " + ByteUtils.HexToString(output));

How to achieve that using Cryptopp
Please help me regarding this..
Sorry i'm pretty new in this field..
Thanks
