My attempts under Linux

I'm using the IDream ID-SMID01 SmartCard reader, bought for 10€

Installing beidgui and dependencies: 

apt-get install beidgui beid-tools
=> libopenct1 libpcsclite1 libbeidlibopensc2 libbeid2 beid-tools beidgui libccid pcscd 
less /usr/share/doc/libbeidlibopensc2/README.Debian

The GUI application works well, including OCSP communication, showing me that my eID certificates are revoked, excellent!

UPDATE: There is a version 2.6.0-3 available in unstable 

apt-get install -t unstable beidgui beid-tools

Exploring

pkcs15-tool --dump
pkcs15-tool --read-certificate 02 > my_auth.crt
pkcs15-tool --read-certificate 03 > my_sign.crt
pkcs15-tool --read-certificate 04 > belgium.crt
pkcs15-tool --read-certificate 06 >> belgium.crt
openssl x509 -in my_auth.crt -text
pkcs15-tool --read-ssh-key 2

Firefox security module

To add the security module to Firefox: 

apt-get install libbeid2-dev libbeidlibopensc2-dev

Visit file:///usr/share/beid/beid-pkcs11-register.html to install the service

Now what?...
cf http://eid.belgium.be/fr_BE/fed_ict/imported_content_eid/pdf/eID-FR-Firefox.pdf
You can see your certificate in Preferences -> Advanced -> Encryption -> View Certificates and you can trust the Belgium Root CA under the "Authorities" tab for e.g. "identifying mail users"

If I try to connect to federal sites like Tax-on-web, being identified by my card, I get an error -12222 even before I'm prompted to type my PIN, is it because my certificates are revoked? 

Error establishing an encrypted connection to... Error Code: -12222.

Thunderbird security module

To add the security module to Firefox: 

apt-get install libbeid2-dev libbeidlibopensc2-dev

Menu preferences->advanced->certificates->security devices->load 

Module name: Belgium Identity Card PKCS#11
Module filename: /usr/lib/libbeidpkcs11.so

You can see your certificate in Preferences -> Advanced -> Encryption -> View Certificates and you can trust the Belgium Root CA under the "Authorities" tab for e.g. "identifying mail users"

Try to sign a first mail:
Menu S-MIME -> Digitally sign this message -> setup certificate -> digital signing -> select your BELPIC auth certif

I could successfully sign (with my PIN) and verify an email but only with the Authentication certificate, not the Signature certificate
According to the snapshots of the official guide of the eID for Outlook, it's ok, the Authentication certificate must be used.

Signing text

From https://securehomes.esat.kuleuven.be/~decockd/wiki/bin/view.cgi/Main/UsingOpenscTOC#using_opensc_smartcards_to_sign

Signing text and extracting the public certificate: 

fortune > data.txt
openssl sha1 -binary data.txt > data.sha1
pkcs15-crypt --key 2 --sign --pkcs1 --sha-1 --input data.sha1 --output data.auth.sig
pkcs15-tool --read-certificate 02 > my_auth.crt

Verifying the signature: 

openssl x509 -in my_auth.crt -pubkey -noout > my_auth.pem
openssl dgst -sha1 -verify my_auth.pem -signature data.auth.sig data.txt

I tried to do the same with the signature certificate instead of the authentication certificate but I get an error: 

pkcs15-crypt --key 3 --sign --pkcs1 --sha-1 --input data.sha1 --output data.auth.sig
[pkcs15-crypt] sec.c:67:sc_set_security_env: returning with: Not supported
[pkcs15-crypt] pkcs15-sec.c:267:sc_pkcs15_compute_signature: sc_set_security_env() failed: Not supported
Compute signature failed: Not supported

SSH

Getting the patch from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=355274 and porting it to v4.7p1
Some rejs easy to solve from v4.2 to v4.7 and one less obvious change in debian/control: fix the debconf dependancies (was ${debconf:Depends} I think): 

Package: openssh-client-sc                                                          
Architecture: any                                                                   
Depends: ${shlibs:Depends}, debconf (>= 1.2.0) | debconf-2.0,...


I recompile ssh with smartcard support. 

apt-get source openssh-client
cd openssh-4.7p1
patch -p1 < ../mypatch
dpkg-buildpackage -uc -us -rfakeroot

Sending my public key to the ssh server: 

pkcs15-tool --read-ssh-key 2 |tail -n1|ssh user@host 'cat - >> ~/.ssh/authorized_keys'

Then logging, being prompted for my PIN: 

ssh -I 0 user@host.com

TODO: SSL Auth

http://blog.eikke.com/index.php/ikke/2007/10/29/using_your_belgian_eid_for_ssl_authentic 

apt-get install libengine-pkcs11-openssl

To generate a request, open a console and launch openssh. Once at the OpenSSL prompt, issue these 2 commands: 

engine -t dynamic -pre SO_PATH:/usr/lib/engines/engine_pkcs11.so -pre ID:pkcs11 -pre LIST_ADD:1 -pre LOAD -pre MODULE_PATH:/usr/lib/opensc-pkcs11.so

Adjust paths if necessary, of course. This loads the pkcs11 engine inside OpenSSL. 

req -engine pkcs11 -new -days 100 -key id_02 -keyform engine -out myrequest.csr -subj "/C=BE/ST=O-VL/O=My Organisation/CN=My Name/emailAddress=my@email.tld"

Adjust the days, out and subj parameters, at least. The key ID can be found using 

pkcs15-tool -c

Use the ID of the Authentication X509 certificate.


TODO: OpenVPN Auth

http://christophe.vandeplas.com/2008/02/03/openvpn-belgian-eid
But Debian openvpn 2.1_cr4 doesn't support yet --show-pkcs11-ids

TODO: Login

I tried https://securehomes.esat.kuleuven.be/~decockd/wiki/bin/view.cgi/Main/UsingOpenscTOC#logging_in_with_smartcards but with the eID. 

apt-get install libpam-p11

See file:///usr/share/doc/libpam-p11/QuickStart.html

openssh way:
Preparing the account with .ssh/authorized_keys, cf SSH auth on this page
Edit /etc/pam.d/login and add before "@include common-auth" sth like: 

auth sufficient pam_p11_openssh.so /usr/lib/opensc-pkcs11.so

/var/log/auth.log tells: no certificates found or 

auth sufficient pam_p11_openssh.so /usr/lib/libbeidpkcs11.so

/var/log/auth.log tells: fatal: pkcs11_sign failed
before I was even prompted for my PIN

opensc way: same results 

auth sufficient pam_p11_opensc.so /usr/lib/opensc-pkcs11.so
auth sufficient pam_p11_opensc.so /usr/lib/libbeidpkcs11.so

preparing the account: 

mkdir ~/.eid
chmod 0755 ~/.eid
pkcs15-tool -r 2 > ~/.eid/authorized_certificates
chmod 0644 ~/.eid/authorized_certificates

So I still couldn't find a way.
