需要jquery/javascript中的Sha1加密

Question

我在php 中有sha1加密编码

<?php
echo hash('sha1', 'testing'.'abcdb');
?>

但是，我的需求应该必须运行页面xyz.html，所以上面的块不起作用。

因此，我需要在jquery/javascript中进行sha1加密。通过提供sha1加密的编码来帮助我。

必须将其转换为脚本

'<?php echo hash('sha1', 'my-secret-key' . $_REQUEST["email"]); ?>'

只需谷歌即可找到：http://phpjs.org/functions/sha1/

调用

sha1('testing'+'abcdb');

有两种方法可以实现这一点，您可以使用AJAX调用PHP页面并检索SHA-1。

或者，您可以使用其中一个JS库，例如CryptoJS。
