    text
    copied!<p>When I attempt to use <code>SecPKCS12Import()</code> from the Security framework as provided by Mac OS X 10.6, the result code is always <code>errSecUnimplemented</code>, regardless of the arguments provided. </p> <p>Furthermore, the linker is unable to find symbols for the constants relevant to this function declared in SecImportExport.h (i.e. <code>kSecImportExportPassphrase</code>, <code>kSecImportItemIdentity</code>, et al.).</p> <p>What on Earth is going on with this library -- is the function implemented or is it not? Why can the linker resolve all other symbols in the framework, but not these? How should I convert a PKCS12-formatted binary blob to a SecIdentityRef or SecCertificateRef and SecKeyRef pair?</p> <p>What am I doing wrong? I'm sure this is a PEBKAC issue. :-)</p> <hr> <p>EDIT: I see that I was very unclear in my question. I'm aware that Security.framework is implemented, given that I am able to use the other functionality it provides without an issue. Given this, I'm fairly certain that I'm linking against the framework correctly, since if I remove the link, none of the symbols can be found -- as expected. When I relink the framework, all the symbols are found, with the exception of the constants relevant to <code>SecPKCS12Import()</code>, e.g. <code>kSecImportExportPassphrase</code>, <code>kSecImportItemIdentity</code>, etc.</p> <p>Given that I cannot use these symbols, I passed in what could have been incorrect strings (<code>@"kSecImportItemIdentity"</code>, etc.), but the error code returned was <code>errSecUnimplemented</code>. This led me to believe that perhaps this specific functionality has not been implemented.</p> <p>I tried using the 10.5 SDK, but that didn't work, of course. :-)</p> <hr> <p>EDIT: My import is just a regular <code>#import &lt;Security/Security.h&gt;</code>. For kicks, I tried <code>#import &lt;Security/SecImportExport.h&gt;</code> as well, but this effected no change. That said, the error is issued by the linker, not the compiler.</p> <p>I ran <code>dyldinfo -export Security.framework/Security</code> to list the symbols exported by the library and found many of the <a href="http://developer.apple.com/mac/library/documentation/Security/Reference/SecurityRefUpdate/Articles/Security_10.5-10.6_SymbolChanges.html#//apple_ref/doc/uid/TP40008013" rel="nofollow noreferrer">new</a> symbols, but <code>kSecImportExportPassphrase</code> and friends were conspicuously missing. This might explain why the linker cannot find the symbols. The symbol for <code>SecPKCS12Import</code> appears in the symbol table and I can call that with no issues, it's just the functionality does not seem to be there.</p>
