Security :: MD5 / Encrypted Sources Can Result In The Same Crypted Array?

reading on the web ive found the code below; i wonder if an encrypted string using this block generates an unique result or if different encrypted sources can result in the same crypted array:

private static TripleDES CreateDES(string password)
{
MD5 md5 = new MD5CryptoServiceProvider();
TripleDES des = new TripleDESCryptoServiceProvider();
des.Key = md5.ComputeHash(Encoding.Unicode.GetBytes(password));
des.IV = new byte[des.BlockSize / 8];
return des;
}
