<p>Intel(R) EPID 1.1 Verifier functionality. </p>
<p>To verify signatures coming from member devices that belong to an Intel® EPID 1.1 group, you need to use Intel® EPID 1.1 verifier APIs.</p>
<p>If you are acting as a verifier for both Intel® EPID 1.1 and 2.0 members, you can determine if you need version 1.1 or 2.0 verification by checking the Intel® EPID version field in the group public key file (see <a class="el" href="group___file_parser.html#ga8e38d1102eb1dd9b5af2e2f79236da55" title="Extracts Intel(R) EPID Binary Output File header information. ">EpidParseFileHeader</a>). You can also check the version in other binary issuer material, such as the GroupRL and SigRL.</p>
<p>The 1.1 verifier APIs take a verifier context as input. Each verifier context (<a class="el" href="group___epid11_verifier_module.html#gabe6a864a06322205ae7536ffea34c702" title="Internal context of Intel(R) EPID 1.1 verifier. ">Epid11VerifierCtx</a>) represents a verifier for a single group.</p>
<p>The Intel® EPID 1.1 specification does not provide hash algorithm selection and verifier blacklist revocation. Therefore, APIs such as <a class="el" href="group___epid_verifier_module.html#ga97b58b2382f24756b66a357f1e825c92" title="Sets the hash algorithm to be used by a verifier. ">EpidVerifierSetHashAlg</a> and <a class="el" href="group___epid_verifier_module.html#ga0909703a0a4dfe080374d0d99077465a" title="Sets the verifier revocation list. ">EpidVerifierSetVerifierRl</a> are not available.</p>
<p>You can find the Intel® EPID 1.1 API headers in the 1.1 directories, for example, <code>epid/verifier/1.1/api.h</code>.</p>
<p>Intel® EPID 1.1 APIs and data structures are indicated with the "Epid11" prefix. For example, the Intel® EPID 1.1 version of <a class="el" href="group___file_parser.html#ga43fdbc1bf2edd3695d21cb457365afbb" title="Extracts group public key from buffer in issuer binary format. ">EpidParseGroupPubKeyFile</a> is called <a class="el" href="group___epid11_file_parser_module.html#ga1f92d1cb6bd7d9815711fde515b40a4c" title="Extracts group public key from buffer in issuer binary format. ">Epid11ParseGroupPubKeyFile</a>, and the Intel® EPID 1.1 version of <code><a class="el" href="struct_group_rl.html" title="group revocation list ">GroupRl</a></code> is <code><a class="el" href="struct_epid11_group_rl.html" title="Intel(R) EPID 1.1 group revocation list.
