function Encrypt(str) {
    if (!str) str = "";
    str = (str == "undefined" || str == "null") ? "" : str;
    try {
        var key = 146;
        var pos = 0;
        ostr = '';
        while (pos < str.length) {
            ostr = ostr + String.fromCharCode(str.charCodeAt(pos) ^ key);
            pos += 1;
        }

        return ostr;
    } catch (ex) {
        return '';
    }
}

function Decrypt(str) {
    if (!str) str = "";
    str = (str == "undefined" || str == "null") ? "" : str;
    try {
        var key = 146;
        var pos = 0;
        ostr = '';
        while (pos < str.length) {
            ostr = ostr + String.fromCharCode(key ^ str.charCodeAt(pos));
            pos += 1;
        }

        return ostr;
    } catch (ex) {
        return '';
    }
}

This isn't a direct answer to the question, but considerations you should take into account with the overall approach:

Though you could do something in jQuery, you should use SSL if at all possible, this is a much more secure way of passing information back and forth to the server if that's your goal.

Encrypting content via JavaScript but still sending it in plain-text really does nothing to thwart man-in-the-middle attacks, which while some people imagine to be rare because you must control some point in the connection...how many people use third-party WiFi, at the coffee house, etc? Anywhere with a public hotspot is easy game for a man-in-the middle, just something to keep in mind.

You can use this proven library: http://pajhome.org.uk/crypt/md5

It's not a jQuery plugin - just call the functions as needed.
