wget ssl alert handshake failure - ssl

Question

I am trying to download files from an https site and keep getting the following error:
OpenSSL: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure
Unable to establish SSL connection.
From reading blogs online I gather I have to provide the server cert and the client cert. I have found steps on how to download the server cert but not the client cert. Does anyone have a complete set of steps to use wget with SSL? I also tried the --no-check-certificate option but that did not work.
wget version: wget-1.13.4
openssl version: OpenSSL 1.0.1f 6 Jan 2014
trying to download all lecture resources from a course's webpage on coursera.org. So, the URL would look something like this: https://class.coursera.org/matrix-002/lecture
Accessing this webpage online requires form authentication, not sure if that is causing the failure.

Answer 1

It works from here with same OpenSSL version, but a newer version of wget (1.15). Looking at the Changelog there is the following significant change regarding your problem:
1.14: Add support for TLS Server Name Indication.
Note that this site does not require SNI. But www.coursera.org requires it.
And if you would call wget with -v --debug (as I've explicitly recommended in my comment!) you will see:
$ wget https://class.coursera.org
...
HTTP request sent, awaiting response...
HTTP/1.1 302 Found
...
Location: https://www.coursera.org/ [following]
...
Connecting to www.coursera.org (www.coursera.org)|54.230.46.78|:443... connected.
OpenSSL: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure
Unable to establish SSL connection.
So the error actually happens with www.coursera.org and the reason is missing support for SNI. You need to upgrade your version of wget.

Answer 2

You probably have an old version of wget. I suggest installing wget using Chocolatey, the package manager for Windows. This should give you a more recent version (if not the latest).
Run this command after having installed Chocolatey (as Administrator):
choco install wget

Answer 3

I was in SLES12 and for me it worked after upgrading to wget 1.14, using --secure-protocol=TLSv1.2 and using --auth-no-challenge.
wget --no-check-certificate --secure-protocol=TLSv1.2 --user=satul --password=xxx --auth-no-challenge -v --debug https://jenkins-server/artifact/build.x86_64.tgz

Answer 4

One alternative is to replace the "https" with "http" in the url that you're trying to download from to just circumvent the SSL connection. Not the most secure solution, but this worked in my case.

Answer 5

I was having this problem on Ubuntu 12.04.3 LTS (well beyond EOL, I know...) and got around it with:
sudo apt-get update && sudo apt-get install ca-certificates

Answer 6

Basically your OpenSSL uses SSLv3 and the site you are accessing does not support that protocol.
Just update your wget:
sudo apt-get install wget
Or if it is already supporting another secure protocol, just add it as argument:
wget https://example.com --secure-protocol=PROTOCOL_v1

Answer 7

Below command for download files from TLSv1.2 website.
curl -v --tlsv1.2 https://example.com/filename.zip
It`s worked!

Answer 8

Otherwise might be just simpler to use curl instead.
There is no peculiar need to specify any option and can be simply:
curl https://example.com/filename.zip
with curl there is no need to add the -v option when facing the wget SSL error.
