<div dir="ltr">I see that the pull request[1] relevant to this was denied last week due to the API surface. For my own understanding, what would be required for these values to be approved to be available through this library (cryptography)? Once I have time I'm planning to contribute the point compression code that I wrote for my project, but the point decompression algorithm requires these curve parameter values.<div><br></div><div>thanks</div><div> --Matt</div><div><br></div><div>[1] <a href="https://github.com/pyca/cryptography/pull/2499">https://github.com/pyca/cryptography/pull/2499</a></div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Jan 27, 2016 at 11:18 PM Matt Bullock <<a href="mailto:matt.s.b.42@gmail.com">matt.s.b.42@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Yup, that looks like that would cover exposing the values I need.

<div dir="ltr">For a project I am working on, I have a need to
encode/decode elliptic curve points using point
compression[1]. As this is not yet supported natively by the
cryptography library, I have started implementing it myself but
have hit a snag. Unlike the uncompressed point encoding, in
order to decode a compressed curve point I need to be able to
reference the curve parameters. I have been searching through
the cryptography documentation and code but cannot find any way of
retrieving these values from the backend.
<div><br></div>
<div>Is there a method for this that I am missing, or is this
functionality not yet available?</div>
