Introduction
With this program, after you click on Open File, you can select any file and after clicking on Open button, you will get MD5 and SHA-1 (SHA1) files' hash. This program is very useful for somebody who wants to get and save some important files' hash. You must note that, if somebody changes even a bit of some content file, the file's hash will be changed. So try it and enjoy it!
For this application, I created a class for getting MD5 and SHA-1 files' hash:
namespace IranianExperts
{
public sealed class DTHasher
{
private DTHasher(){}
private static byte[] ConvertStringToByteArray(string data)
{
return(new System.Text.UnicodeEncoding()).GetBytes(data);
}
private static System.IO.FileStream GetFileStream(string pathName)
{
return(new System.IO.FileStream(pathName, System.IO.FileMode.Open,
System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite));
}
public static string GetSHA1Hash(string pathName)
{
string strResult = "";
string strHashData = "";
byte[] arrbytHashValue;
System.IO.FileStream oFileStream = null;
System.Security.Cryptography.SHA1CryptoServiceProvider oSHA1Hasher=
new System.Security.Cryptography.SHA1CryptoServiceProvider();
try
{
oFileStream = GetFileStream(pathName);
arrbytHashValue = oSHA1Hasher.ComputeHash(oFileStream);
oFileStream.Close();
strHashData = System.BitConverter.ToString(arrbytHashValue);
strHashData = strHashData.Replace("-", "");
strResult = strHashData;
}
catch(System.Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message, "Error!",
System.Windows.Forms.MessageBoxButtons.OK,
System.Windows.Forms.MessageBoxIcon.Error,
System.Windows.Forms.MessageBoxDefaultButton.Button1);
}
return(strResult);
}
public static string GetMD5Hash(string pathName)
{
string strResult = "";
string strHashData = "";
byte[] arrbytHashValue;
System.IO.FileStream oFileStream = null;
System.Security.Cryptography.MD5CryptoServiceProvider oMD5Hasher=
new System.Security.Cryptography.MD5CryptoServiceProvider();
try
{
oFileStream = GetFileStream(pathName);
arrbytHashValue = oMD5Hasher.ComputeHash(oFileStream);
oFileStream.Close();
strHashData = System.BitConverter.ToString(arrbytHashValue);
strHashData = strHashData.Replace("-", "");
strResult = strHashData;
}
catch(System.Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message, "Error!",
System.Windows.Forms.MessageBoxButtons.OK,
System.Windows.Forms.MessageBoxIcon.Error,
System.Windows.Forms.MessageBoxDefaultButton.Button1);
}
return(strResult);
}
}
}
