<h2>Detailed Description</h2>
<p>The QSslCipher class represents an SSL cryptographic cipher.</p>
<p>QSslCipher stores information about one cryptographic cipher. It is most commonly used with <a href="qsslsocket.html">QSslSocket</a>, either for configuring which ciphers the socket can use, or for displaying the socket's ciphers to the user.</p>
<p>See also <a href="qsslsocket.html">QSslSocket</a> and <a href="qsslkey.html">QSslKey</a>.</p>

<h2>Member Function Documentation</h2>
<a name="//apple_ref/cpp/instm/QSslCipher/QSslCipher"></a>
<h3 class="fn"><a name="QSslCipher"></a>QSslCipher::QSslCipher ()</h3>
<p>Constructs an empty <a href="qsslcipher.html">QSslCipher</a> object.</p>
<h3 class="fn"><a name="QSslCipher-2"></a>QSslCipher::QSslCipher ( const <a href="qstring.html">QString</a> & <i>name</i>, <a href="qssl.html#SslProtocol-enum">QSsl::SslProtocol</a> <i>protocol</i> )</h3>
<p>Constructs a <a href="qsslcipher.html">QSslCipher</a> object for the cipher determined by <i>name</i> and <i>protocol</i>. The constructor accepts only supported ciphers (i.e., the <i>name</i> and <i>protocol</i> must identify a cipher in the list of ciphers returned by <a href="qsslsocket.html#supportedCiphers">QSslSocket::supportedCiphers</a>()).</p>
<p>You can call <a href="qsslcipher.html#isNull">isNull</a>() after construction to check if <i>name</i> and <i>protocol</i> correctly identified a supported cipher.</p>
<h3 class="fn"><a name="QSslCipher-3"></a>QSslCipher::QSslCipher ( const QSslCipher & <i>other</i> )</h3>
<p>Constructs an identical copy of the <i>other</i> cipher.</p>
<a name="//apple_ref/cpp/instm/QSslCipher/~QSslCipher"></a>
<h3 class="fn"><a name="dtor.QSslCipher"></a>QSslCipher::~QSslCipher ()</h3>
<p>Destroys the <a href="qsslcipher.html">QSslCipher</a> object.</p>
<a name="//apple_ref/cpp/instm/QSslCipher/authenticationMethod"></a>
<h3 class="fn"><a name="authenticationMethod"></a><a href="qstring.html">QString</a> QSslCipher::authenticationMethod () const</h3>
<p>Returns the cipher's authentication method as a <a href="qstring.html">QString</a>.</p>
<a name="//apple_ref/cpp/instm/QSslCipher/encryptionMethod"></a>
<h3 class="fn"><a name="encryptionMethod"></a><a href="qstring.html">QString</a> QSslCipher::encryptionMethod () const</h3>
<p>Returns the cipher's encryption method as a <a href="qstring.html">QString</a>.</p>
<a name="//apple_ref/cpp/instm/QSslCipher/isNull"></a>
<h3 class="fn"><a name="isNull"></a>bool QSslCipher::isNull () const</h3>
<p>Returns true if this is a null cipher; otherwise returns false.</p>
<a name="//apple_ref/cpp/instm/QSslCipher/keyExchangeMethod"></a>
<h3 class="fn"><a name="keyExchangeMethod"></a><a href="qstring.html">QString</a> QSslCipher::keyExchangeMethod () const</h3>
<p>Returns the cipher's key exchange method as a <a href="qstring.html">QString</a>.</p>
<a name="//apple_ref/cpp/instm/QSslCipher/name"></a>
<h3 class="fn"><a name="name"></a><a href="qstring.html">QString</a> QSslCipher::name () const</h3>
<p>Returns the name of the cipher, or an empty <a href="qstring.html">QString</a> if this is a null cipher.</p>
<p>See also <a href="qsslcipher.html#isNull">isNull</a>().</p>
<a name="//apple_ref/cpp/instm/QSslCipher/protocol"></a>
<h3 class="fn"><a name="protocol"></a><a href="qssl.html#SslProtocol-enum">QSsl::SslProtocol</a> QSslCipher::protocol () const</h3>
<p>Returns the cipher's protocol type, or <a href="qssl.html#SslProtocol-enum">QSsl::UnknownProtocol</a> if <a href="qsslcipher.html">QSslCipher</a> is unable to determine the protocol (<a href="qsslcipher.html#protocolString">protocolString</a>() may contain more information).</p>
<p>See also <a href="qsslcipher.html#protocolString">protocolString</a>().</p>
<a name="//apple_ref/cpp/instm/QSslCipher/protocolString"></a>
<h3 class="fn"><a name="protocolString"></a><a href="qstring.html">QString</a> QSslCipher::protocolString () const</h3>
<p>Returns the cipher's protocol as a <a href="qstring.html">QString</a>.</p>
<p>See also <a href="qsslcipher.html#protocol">protocol</a>().</p>
<a name="//apple_ref/cpp/instm/QSslCipher/supportedBits"></a>
<h3 class="fn"><a name="supportedBits"></a>int QSslCipher::supportedBits () const</h3>
<p>Returns the number of bits supported by the cipher.</p>
<p>See also <a href="qsslcipher.html#usedBits">usedBits</a>().</p>
<a name="//apple_ref/cpp/instm/QSslCipher/usedBits"></a>
<h3 class="fn"><a name="usedBits"></a>int QSslCipher::usedBits () const</h3>
<p>Returns the number of bits used by the cipher.</p>

<a name="//apple_ref/cpp/instm/QSslCipher/operator!="></a>
<h3 class="fn"><a name="operator-not-eq"></a>bool QSslCipher::operator!= ( const QSslCipher & <i>other</i> ) const</h3>
<p>Returns true if this cipher is not the same as <i>other</i>; otherwise, false is returned.</p>
<a name="//apple_ref/cpp/instm/QSslCipher/operator="></a>
<h3 class="fn"><a name="operator-eq"></a>QSslCipher & QSslCipher::operator= ( const QSslCipher & <i>other</i> )</h3>
<p>Copies the contents of <i>other</i> into this cipher, making the two ciphers identical.</p>
<a name="//apple_ref/cpp/instm/QSslCipher/operator=="></a>
<h3 class="fn"><a name="operator-eq-eq"></a>bool QSslCipher::operator== ( const QSslCipher & <i>other</i> ) const</h3>
<p>Returns true if this cipher is the same as <i>other</i>; otherwise, false is returned.</p>
