<p style="margin: 10px 0 0 0">And the constructors and destructors also have some <tt>#ifdef</tt> action to initialise the structure and the pointer prior to 1.1 and to allocate the structure post 1.1.</p>
<p style="margin: 10px 0 0 0">I view that this is abstracted enough.</p>

<p style="margin: 10px 0 0 0">There is an impedance match between Santuario and OpenSSL. The former believes that you can set fields individually the latter doesn't (so you cannot just set the q in a DSA). So >= 1.1 we accumulate them and then call OpenSSL when we can. I chose to keep the old behavior for < 1.1 in case someone is bitten by this.</p>
<p style="margin: 10px 0 0 0">For an example look at (for example) <tt>OpenSSLCryptoKeyDSA::setGBase</tt>.</p>
<h3 style="margin: 10px 0 0 0; font-size: 16px; line-height: 1.563; margin: 30px 0 0 0"><a name="Abstractablecases" style="color: #3b73af; text-decoration: none"></a>Abstractable cases</h3>
<p style="margin: 10px 0 0 0">Finally there are a hand full of cases (mostly in the three clone cases and the three <tt>EVP_PKEY*</tt> constructors) where we could abstract some/all of the new functions out. Initially there were just these six cases, and it seems like little to pay. But then there are the tools. A good third of all the changes are of this type and in the tools (which we don't ship) and about 95% of this case is in the tools.</p>
<p style="margin: 10px 0 0 0">However, given that we (Shibboleth) do not have unit tests for the tools it might be a good idea to do this abstraction in a common file, then we can test this in Shib and be more confident for the tools.</p>
<p style="margin: 10px 0 0 0">This will be a complete new patch stream (and test against both Versions). I'll do it as a rebase. </p>
<p style="margin: 10px 0 0 0">I'd advise Scott to hold off review.</p>
