+## Safenet eToken E5110
+
+No Debian, instale o [MUSCLE](https://pcsclite.alioth.debian.org/):
+
+    sudo apt install libccid pcsc-tools pcscd pcscd libpcsclite1
+
+Plugue a parada e execute:
+
+    opensc-tool --list-readers
+
+## SafeNet Authentication Client
+
+Para uso no mundo corporativo e institucional, como OAB e afins. Você não vai
+querer usar os drivers proprietários a não ser que seja forçado, certo?
+
+Curioso que no fim das contas a OAB conseguiu seu lugar ao sol no mercado
+da certificação digital apesar da implantação do modelo governamental escolhido
+para o certificado raíz brasileiro, história contada no livro
+[Leviatã Eletrônico](http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-45222010000300013).
+
+Enfim, pra usar o eToken E5110 pra assinar documentos no navegador você
+precisará de drivers específicos e proprietários.
+
+Aparentemente a [Gemalto comprou a SafeNet](http://www.gemalto.com/press/Pages/Gemalto-to-acquire-SafeNet,the-worldwide-leader-in-data-and-software-protection.aspx)
+e depois ficou muito mais difícil para baixar o driver do eToken E5110, que além de ser proprietário ainda ficou privativo!
+Maluco fez [até script](https://gist.github.com/dex4er/1354710) pra automatizar essa zica.
+[Aqui](https://site.solutinet.com.br/2015/manuais/instaladores/) há versões recentes das bibliotecas e do cliente de autenticação
+proprietário (dica [daqui](https://diadialinux.wordpress.com/2017/03/02/instalar-etoken-alladin-usar-sites-do-governo-com-certificado-digital-e-assinar-documentos-pdf/)).
