A PHP compatible MD5 function in c#
By Justin Silverton
The following is a function written in c# that will return a PHP compatible MD5 hash of a file, given the name. The equivalent function in PHP is md5_file().
public string MD5Hash( string sFilePath )
{
try
{
MD5CryptoServiceProvider md5Provider
= new MD5CryptoServiceProvider();
FileStream fs
= new FileStream(sFilePath, FileMode.Open, FileAccess.Read);
Byte[] hashCode
= md5Provider.ComputeHash(fs);
string ret = "";
foreach (byte a in hashCode)
{
if (a<16)
ret += "0" + a.ToString ("x");
else
ret += a.ToString ("x");
}
fs.Close();
return ret;
}
catch( Exception ex )
{
throw ex;
}
}
