So you have received a version of the error: 14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure error while trying to install a Magento Connect extension?

We have your solution! It seems that this week, Magento Connect turned off SSLv3 (a good thing), but Magento still wants to connect with SSLv3 in Curl.

Just download this file and drop it over your Magento install.

1. Download this file.
2. Unzip then go to your root folder of your site (usually html, public or public_html – where you’re downloader folder sites).
3. Drop the downloader folder over it. (alternatively, you can upload the included file to the same path on your server as it is in the download.)

You can also just manually editing downloader/lib/Mage/HTTP/Client/Curl.php

$this->curlOption(CURLOPT_SSL_VERIFYHOST, 2);
$this->curlOption(CURLOPT_SSL_CIPHER_LIST, 'TLSv1');

Let us know if you have any questions!
