title="Criptografia de chave pública">chaves públicas</a>, utilizam-se duas chaves distintas: a chave de encriptação e a de desencriptação. A chave de encriptação é publicada para qualquer um usar para encriptar suas mensagens. Porém, somente o grupo destinatário têm acesso à chave de desencriptação, que é secreta e que permite que as mensagens sejam lidas.<sup id="cite_ref-disponibilidade_4-0" class="reference"><a href="#cite_note-disponibilidade-4"><span>[</span>4<span>]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Ver_também"><span id="Ver_tamb.C3.A9m"></span>Ver também</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Encripta%C3%A7%C3%A3o&veaction=edit&section=4" title="Editar secção: Ver também" class="mw-editsection-visualeditor"><span>editar</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Encripta%C3%A7%C3%A3o&action=edit&section=4" title="Editar código-fonte da secção: Ver também"><span>editar código-fonte</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Criptografia" title="Criptografia">Criptografia</a></li></ul> <h2 id="Referências" style="cursor: help;" title="Esta seção foi configurada para não ser editável diretamente.
