有没有更好的方法来加密/写入这些md5唯一链接？

Question

我目前正在尝试使用md5哈希创建唯一的网址。我知道这项技术正在变得多余，但对于我的预期用途并不需要很复杂。

 string offerURL = HttpContext.Current.Server.UrlEncode(KookConfiguration.ConfigurationManager.AppSettings["live_sURL"] + "offer/" + offerTitle.Replace(" ", "") + "-" + offerID + ".aspx");

        string uniqueOfferFB = offerURL + "%3Fshareid=" + userID.ToString() + "-" + offerID.ToString() + "-" + TypeID.ToString() + "-FB"; //Facebook
        string uniqueOfferTW = offerURL + "%3Fshareid=" + userID.ToString() + "-" + offerID.ToString() + "-" + TypeID.ToString() + "-TW"; //Twitter
        string uniqueOfferEM = offerURL + "%3Fshareid=" + userID.ToString() + "-" + offerID.ToString() + "-" + TypeID.ToString() + "-EM" + "%0D%0A%0D%0A" + "Sent from the sample.com website"; //Email

        //md5 facebook
        byte[] encodedUniqueOfferFB = new UTF8Encoding().GetBytes(uniqueOfferFB);

        byte[] FBhash = ((HashAlgorithm)CryptoConfig.CreateFromName("MD5")).ComputeHash(encodedUniqueOfferFB);

        //md5 Twitter
        byte[] encodedUniqueOfferTW = new UTF8Encoding().GetBytes(uniqueOfferTW);

        byte[] TWhash = ((HashAlgorithm)CryptoConfig.CreateFromName("MD5")).ComputeHash(encodedUniqueOfferTW);

        //md5 Email
        byte[] encodedUniqueOfferEM = new UTF8Encoding().GetBytes(uniqueOfferEM);

        byte[] EMhash = ((HashAlgorithm)CryptoConfig.CreateFromName("MD5")).ComputeHash(encodedUniqueOfferEM);
