Answer 1

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 '';
    }
}
