Hello Luigi

These is build in at the .NET Framework.
System.Security.Cryptography

for example (not tested):

private string GetFileHash(byte[] file) {
MD5 hasher = MD5.Create();
byte[] data = hasher.ComputeHash(file);
StringBuilder sb = new StringBuilder();

foreach (byte d in data)
sb.Append(d.ToString("x2"));

return sb.ToString();
}
