AES enkripcija i dekripcija
Pozdrav svima nadam se da ce se nac netko tko ce mi znat rec u cemu grjesin
Radim program za digitalni pecat i koristim se asimetricnim algoritmom rsa i asimetricnim aes i imam problem kod ovog drugog
Evo izvorni kod
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Security.Cryptography;
namespace Digitalni_potpis
{
class AES
{
public byte[] encryptStringToBytes_AES(string plainText, byte[] Key, byte[] IV)
{
RijndaelManaged Cipher = new RijndaelManaged();
ICryptoTransform Encryptor = Cipher.CreateEncryptor(Key, IV);
MemoryStream mStream = new MemoryStream();
CryptoStream cStream = new CryptoStream(mStream, Encryptor, CryptoStreamMode.Write);
byte[] plainBytes = UnicodeEncoding.Unicode.GetBytes(plainText);
cStream.Write(plainBytes, 0, plainBytes.Length-1);
cStream.FlushFinalBlock();
return mStream.ToArray();
}
public string decryptStringFromBytes_AES(byte[] cipherText, byte[] Key, byte[] IV)
{
byte[] cipherBytes = cipherText;
RijndaelManaged Cipher = new RijndaelManaged();
ICryptoTransform Decryptor = Cipher.CreateDecryptor(Key, IV);
MemoryStream ms = new MemoryStream(cipherText);
CryptoStream cs = new CryptoStream(ms, Decryptor, CryptoStreamMode.Read);
byte[] plainBytes = new byte[cipherText.Length];
cs.Read(plainBytes, 0, cipherText.Length-1);
return UnicodeEncoding.Unicode.GetString(plainBytes);
}
}
}
Prilikom debagiranja javi mi gresku da je padding invalid stavljao sam PaddingMode.PKCS7 i jos neke ponudene al ne ide
Ako netko zna u cemu je rijec bio bih mu zahvalan
Pozdrav

, time si u potpunosti iskljucio neporecivost jer svako sa pristupom bazi moze da dodje do privatnog kljuca.
