## 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/)).
