I have sha1 encryption coding in php

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

but, my requirement should have to run the page xyz.html, so the above block is not working.

So, I need to do sha1 encryption in jquery/javascript. Help me by providing coding for sha1 encryption.

this is exactly have to be converted to scripts

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

• javascript
• jquery
• sha1

• 3 sha1 isn't an ecryption. Better think of it as a lossy pression. – enthus1ast Commented Mar 17, 2015 at 12:40
• its not working, i have to convert "'<?php echo hash('sha1', 'my-secret-key' . $_REQUEST["email"]); ?>'" to scripts – itsme Commented Mar 17, 2015 at 12:59
• 1 @itsme You do realize that your key won't be secret if you have it in javascript, right? What isn't working? What do you get? What do you expect? Do you get an error? A wrong value? – h2ooooooo Commented Mar 17, 2015 at 13:07
• 1 If you're encrypting someone on the client side, you're doing it wrongly. The client should not receive the encryption key at the first place. The best way is to place an AJAX call to the server, which receives the content (i.e. the email address), and returns the hashed/encrypted content. – Terry Commented Mar 17, 2015 at 13:08

Just google it and found: http://phpjs/functions/sha1/

call

sha1('testing'+'abcdb');

There are two ways to go about this, you can either use AJAX to call up your PHP page and retrieve the SHA-1.

Or, you could use one of the JS libraries, such as CryptoJS.
