<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>Constructs a <a href="qsslcipher.html">QSslCipher</a> object for the cipher determined by <i>name</i> and <i>protocol</i>.
