记住用户名密码
用简单的算法,对邮箱地址进行加密,解密:
<?phpfunction deCFEmail($encode){ $k = hexdec(substr($encode,0,2)); for($i=2, $m=''; $i < strlen($encode) - 1; $i += 2){ $m.=chr(hexdec(substr($encode, $i, 2))^$k); } return $m; }function encodeEmail($email, $key=0) { $chars = str_split($email); $string = ''; $key = $key ? $key : rand(10, 99); foreach ($chars as $value) { $string .= sprintf("%02s", dechex(ord($value)^$key)); } return dechex($key).$string; }echo encodeEmail("abc@abc.com")." ";echo deCFEmail("4c2d2e2f0c2d2e2f622f2321")." ";?>
对应的js:
<script> !function () { "use strict"; function e(e) { try { if ("undefined" == typeof console) return; "error" in console ? console.error(e) : console.log(e) } catch (e) { } } function t(e) { return d.innerHTML = '<a href="' + e.replace(/"/g, """) + '"></a>', d.childNodes[0].getAttribute("href") || "" } function r(e, t) { var r = e.substr(t, 2); return parseInt(r, 16) } function n(n, c) { for (var o = "", a = r(n, c), i = c + 2; i < n.length; i += 2) { var l = r(n, i) ^ a; o += String.fromCharCode(l) } try { o = decodeURIComponent(escape(o)) } catch (u) { e(u) } return t(o) } function c(t) { for (var r = t.querySelectorAll("a"), c = 0; c < r.length; c++)try { var o = r[c], a = o.href.indexOf(l); a > -1 && (o.href = "mailto:" + n(o.href, a + l.length)) } catch (i) { e(i) } } function o(t) { for (var r = t.querySelectorAll(u), c = 0; c < r.length; c++)try { var o = r[c], a = o.parentNode, i = o.getAttribute(f); if (i) { var l = n(i, 0), d = document.createTextNode(l); a.replaceChild(d, o) } } catch (h) { e(h) } } function a(t) { for (var r = t.querySelectorAll("template"), n = 0; n < r.length; n++)try { i(r[n].content) } catch (c) { e(c) } } function i(t) { try { c(t), o(t), a(t) } catch (r) { e(r) } } var l = "/cdn-cgi/l/email-protection#", u = ".__cf_email__", f = "data-cfemail", d = document.createElement("div"); i(document), function () { var e = document.currentScript || document.scripts[document.scripts.length - 1]; e.parentNode.removeChild(e) }() }();</script>
使用方式:
<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="4c2d2e2f0c2d2e2f622f2321">[email protected]</a>
