 <p>It is essential that you verify the integrity of the downloaded file using the PGP signature (.asc file) or a hash (.md5 or .sha* file). Please read <a class="reference external" href="https://www.apache.org/info/verification.html">Verifying Apache Software Foundation Releases</a> for more information on why you should verify our releases.</p>
 <p>The PGP signature can be verified using PGP or GPG. First download the KEYS as well as the .asc signature file for the relevant distribution. Make sure you get these files from the main distribution site, rather than from a mirror. Then verify the signatures using one of the following alternatives:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>% gpg --import KEYS
 % gpg --verify downloaded_file.asc downloaded_file
 </pre></div>
 </div>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>% pgpk -a KEYS
 % pgpv downloaded_file.asc
 </pre></div>
 </div>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>% pgp -ka KEYS
 % pgp downloaded_file.asc
 </pre></div>
 </div>
 <p>Alternatively, you can verify the hash on the file.</p>
 <p>Hashes can be calculated using GPG:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>% gpg --print-md SHA1 downloaded_file
 </pre></div>
 </div>
 <p>The output should be compared with the contents of the SHA1 file. Similarly for other hashes (SHA256 MD5 etc) which may be provided.</p>
 <p>Windows 7 and later systems should all now have <code class="docutils literal"><span class="pre">certUtil</span></code>:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>% certUtil -hashfile pathToFileToCheck
 </pre></div>
 </div>
 <p>HashAlgorithm choices: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512</p>
 <p>Unix-like systems (and macOS) will have a utility called <code class="docutils literal"><span class="pre">md5</span></code>, <code class="docutils literal"><span class="pre">md5sum</span></code> or <code class="docutils literal"><span class="pre">shasum</span></code>.</p>

             Apache MXNet is an effort undergoing incubation at The Apache Software Foundation (ASF), <strong>sponsored by the <i>Apache Incubator</i></strong>. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
