uninitialized constant OpenSSL::PKey::EC error about letsencrypt-webfaction

[will-in-wi]

The problem is that you are probably using a CentOS 5 box. It has an older version of OpenSSL which doesn't support the Elliptic Curve (EC) Algorithm which json-jwt depends on. This is why the Readme says:

The CentOS 5 systems do not have a new enough OpenSSL to include the algorithms required. You may be able to make this work using rbenv and compiling openssl yourself.

I want to put together a tutorial for compiling a custom OpenSSL for CentOS 5 and then using RBenv to make this work, but I haven't had time yet.

If your server is not <= web299 and <= dweb88, please let me know. it may be another issue I'm not yet aware of.

Yeah my server is <web299 so seems to be that issue, I did try and build a local copy of openssl in my home directory but failed. Was following these steps.

[will-in-wi]

I've built a first draft of a tutorial here: https://github.com/will-in-wi/letsencrypt-webfaction/wiki/Install-custom-OpenSSL-and-Ruby-on-CentOS-5-host

However, I haven't yet been successful in getting RBEnv to use my custom OpenSSL.

[will-in-wi]

I just got it to work and modified the instructions.

[ryanseddon]

Great thanks those steps worked but I'm still getting the same error when I run letsencrypt_webfaction --config ~/config.yml?

[will-in-wi]

What's the output of type letsencrypt_webfaction?

[will-in-wi]

And type ruby and ruby -ropenssl -e "puts OpenSSL::PKey::EC"?

[ryanseddon]

[username@webxxx ~]$ type letsencrypt_webfaction
letsencrypt_webfaction is a function
letsencrypt_webfaction ()
{
    PATH=$PATH:$GEM_HOME/bin GEM_HOME=$HOME/.letsencrypt_webfaction/gems RUBYLIB=$GEM_HOME/lib ruby2.2 $HOME/.letsencrypt_webfaction/gems/bin/letsencrypt_webfaction $*
}

[username@webxxx ~]$ type ruby
ruby is /usr/local/bin/ruby
[username@webxxx ~]$ rbenv local
2.2.4

[username@webxxx ~]$ ruby -ropenssl -e "puts OpenSSL::PKey::EC"
-e:1: uninitialized constant OpenSSL::PKey::EC (NameError)

[ryanseddon]

I feel like this may be in a weird state from me trying to use system ruby first and then trying rbenv

[will-in-wi]

For me, type ruby returns /home/myuser/.rbenv/shims/ruby

I'm guessing that you either need to restart your shell or add eval "$(rbenv init -)" to your .bash_profile.

[ryanseddon]

Got it!

I deleted letsencrypt_webfaction function from .bash_profile and then did a gem install letsencrypt_webfaction once my ruby was pointing to the right location.

I had to also do this so as not to get an SSL error googleapis/google-api-ruby-client#235 (comment)

Thanks a lot for your help!

[will-in-wi]

Wonderful! Glad to hear it worked.
