Stratus Magento 1 Guides - Magento 1.9 Unknown cipher in list
If you have updated Magento to 1.9.2, you may encounter this error when using the downloader. The problem is due to older ciphers.
This is fixed by adjusting one line of code.
To correct this, in downloader/lib/Mage/HTTP/Client/Curl.php, change:
$this\-\>curlOption(CURLOPT_SSL_CIPHER_LIST, 'TLSv1');
to
$this->curlOption(CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
