C# Program gets stuck
- by weirdcsharp
The program never prints out "test" unless I set a breakpoint on it and step over myself. I don't understand what's happening. Appreciate any help.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
string testKey = "lkirwf897+22#bbtrm8814z5qq=498j5";
string testIv = "741952hheeyy66#cs!9hjv887mxx7@8y";
string testValue = "random";
string encryptedText = EncryptRJ256(testKey, testIv, testValue);
string decryptedText = DecryptRJ256(testKey, testIv, encryptedText);
Console.WriteLine("encrypted: " + encryptedText);
Console.WriteLine("decrypted: " + decryptedText);
Console.WriteLine("test");
}
public static string DecryptRJ256(string key, string iv, string text)
{
string sEncryptedString = text;
RijndaelManaged myRijndael = new RijndaelManaged();
myRijndael.Padding = PaddingMode.Zeros;
myRijndael.Mode = CipherMode.CBC;
myRijndael.KeySize = 256;
myRijndael.BlockSize = 256;
byte[] keyByte = System.Text.Encoding.ASCII.GetBytes(key);
byte[] IVByte = System.Text.Encoding.ASCII.GetBytes(iv);
ICryptoTransform decryptor = myRijndael.CreateDecryptor(keyByte, IVByte);
byte[] sEncrypted = Convert.FromBase64String(sEncryptedString);
byte[] fromEncrypt = new byte[sEncrypted.Length + 1];
MemoryStream msDecrypt = new MemoryStream(sEncrypted);
CryptoStream csDecrypt = new CryptoStream(msDecrypt, decryptor, CryptoStreamMode.Read);
csDecrypt.Read(fromEncrypt, 0, fromEncrypt.Length);
return Encoding.ASCII.GetString(fromEncrypt);
}
public static string EncryptRJ256(string key, string iv, string text)
{
string sToEncrypt = text;
RijndaelManaged myRijndael = new RijndaelManaged();
myRijndael.Padding = PaddingMode.Zeros;
myRijndael.Mode = CipherMode.CBC;
myRijndael.KeySize = 256;
myRijndael.BlockSize = 256;
byte[] keyByte = Encoding.ASCII.GetBytes(key);
byte[] IVByte = Encoding.ASCII.GetBytes(iv);
ICryptoTransform encryptor = myRijndael.CreateEncryptor(keyByte, IVByte);
MemoryStream msEncrypt = new MemoryStream();
CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write);
byte[] toEncrypt = System.Text.Encoding.ASCII.GetBytes(sToEncrypt);
csEncrypt.Write(toEncrypt, 0, toEncrypt.Length);
csEncrypt.FlushFinalBlock();
byte[] encrypted = msEncrypt.ToArray();
return Convert.ToBase64String(encrypted);
}
}
edit:
Tried Debug.WriteLine
Debug.WriteLine("encrypted: " + encryptedText);
Debug.WriteLine("decrypted: " + decryptedText);
Debug.WriteLine("test");
Output:
encrypted: T4hdAcpP5MROmKLeziLvl7couD0o+6EuB/Kx29RPm9w=
decrypted: randomtest
Not sure why it's not printing the line terminator.
