Loaded EC Private key does not match what was originally input

[vikramraja1995]

Hey there,

I am trying to load a private ecdsa key (in pem format) to be used for signing. I was having several issues with my signed tokens, so I did some debugging. Here is a code snippet (using a throwaway private key):

require 'openssl'

key_string = "-----BEGIN EC PRIVATE KEY-----
MHcCAQEEINOov9ihnWNoJd5ER6kj0/b5ZvZkBycx8wxNA7N9e4FpoAoGCCqGSM49
AwEHoUQDQgAEB3tH41EaU+eT+R3GtPvLDR8GucWLQlouTX1lXFmEnOoeCITi/w4E
VUx6NAn7/Xve7pAOAPSt4fO+FLhPPTBmsQ==
-----END EC PRIVATE KEY-----"

original_key = OpenSSL::PKey::EC.new(key_string)
puts original_key.to_pem

Here, you would expect the output from original_key.to_pem to match key_string. This is the case in Ruby 2.3.0, but in JRuby 1.7.27 (and JRuby 9.2.7.0), this is what my output looks like:

-----BEGIN EC PRIVATE KEY-----
MCUCAQEEINOov9ihnWNoJd5ER6kj0/b5ZvZkBycx8wxNA7N9e4Fp
-----END EC PRIVATE KEY-----

I have been trying to figure out why this is happening for a while now, and I am stumped. Does anyone know what's going on, and how I can get it to work properly.

Thanks!

PKey::EC support isn't 'complete' - we could use a helping hand figuring this one out.
not sure what's going on here but instead of looking at pem outputs would try figuring out the parameters, unfortunately PKey::EC#to_text isn't implemented - could be a good starting point.

Hmm okay, will continue debugging and see what I can come up with, thanks!

closing this one in favor of: #257 (while this was reported earlier the later is more up-to-date).
