JBoss Takes on SpringSource with Open Choice Trio » 03/18/2010 3 Common Causes of Unknown SSL Protocol Errors with cURL I see a lot of people hitting this site looking for reasons as to why curl is logging the following curl 35 unknown ssl protocol error in connection to rubygems org 443 message when an SSL connection is attempted: curl: (35) Unknown SSL protocol error in connection
Curl (35) Unknown Ssl Protocol Error In Connection To 443
to ${some_server} So, I thought it would be helpful to publish my 3 most common reasons why I've experienced this error during my curl https unknown protocol web mastering career. It should not serve as an end-all list but it should provide some quick pointers. The Destination Site Does Not Like the Protocol Let's take my Techstacks Tools site as an example. Firing off a curl (35) unsupported ssl protocol version request like the following, results in the Unknown SSL Protocol error: curl --sslv2 https://techstacks-tools.appspot.com/ Why? Well, in this case it is because the techstacks tools site does not support SSLv2, thus, generating the curl (35) error. The Destination Site Does Not Like the Cipher You could be trying to connect to the site using an ssl cipher that the site is configured to reject. For example, anonymous ciphers are typically disabled on ssl-encrypted sites that

are customer-facing. (Many of us set a blanket rejection policy on any SSL-encrypted web site—regardless of it's purpose.) The following command string "can" also result in the curl (35) error: curl --ciphers ADH-RC4-MD5 https://some_web_site.some_domain.com/ Unfortunately, the type of error response you can get from curl depends largely upon the ssl server. On some sites, you'll receive the Unknown SSL Protocol error but on my techstacks-tools site, I get: curl: (35) error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure Kudos to Google because this particular error is a bit more descriptive than the one my websites at work generate because this at least tells you that a ssl socket was started but because of handshake failures, the socket was never able to complete. Try connecting to the site with a cipher that the site supports. Not sure which cipher to use? Well, let me introduce my cryptonark ssl cipher tester... The SSL Private Key Has Expired I came across this one earlier today working with an old WebSeAL site. In IBM GSKit, you can specify how long the private key password is valid. After reaching a certain date, you will still be able to get webseal started and listening on port 443 (or whatever you set your https-port value to) but you will not be able to successfully negotiate an SSL session. In today's case, the old Web
