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 curl error:140770fc:ssl routines:ssl23_get_server_hello:unknown protocol as to why curl is logging the following message when an SSL connection ssl23_get_server_hello:unsupported protocol is attempted: curl: (35) Unknown SSL protocol error in connection 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 web mastering career. It should not serve as an end-all list but it should provide some quick pointers. The Destination https://github.com/paypal/PayPal-PHP-SDK/issues/484 Site Does Not Like the Protocol Let's take my Techstacks Tools site as an example. Firing off a 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 http://blog.techstacks.com/2010/03/3-common-causes-of-unknown-ssl-protocol-errors-with-curl.html 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
