# linux-egradjani
Steps on how to set up the Croatian e-Građani app for identification (Chrome/Firefox) and signing documents (LibreOffice) on Linux (Ubuntu 21.04.)
## Linux requirements
1. Install smart-card reader tooling
```bash
# if on Ubunt 22.04 LTS keep only `pcsc-tools` `opensc` packages and try without others
# in case modutil is missing install `libnss3-tools` as well
sudo apt-get install -y libccid ccid pcsc-tools opensc
```
2. Start the service
```bash
sudo systemctl start pcscd.service
sudo systemctl enable pcscd.service
```
## e-egradjani requirements
To use your ID certificates, you must activate your eOI, and check [eid.hr](https://eid.hr/hr/eosobna/clanci/aktiviraj-eoi) for steps.
There you should find the latest linux `.deb` package. For the previous versions check [here](https://eid.hr/hr/eosobna/clanci/ranije-verzije-middlewara).
## Step-by-step
1. Download `eidmiddleware` app that contains all services, certificates, etc.
```bash
sudo dpkg -i eidmiddleware_vX.Y.Z_amd64.deb
```
2. Create a new local NSS db
```bash
rm -rf $HOME/.pki/nssdb
mkdir -p $HOME/.pki/nssdb
# if on Ubunt 22.04 LTS skip this command
sudo chmod 777 /etc/pam_pkcs11/nssdb
certutil -d $HOME/.pki/nssdb -N --empty-password
sudo chmod 777 $HOME/.pki/nssdb/pkcs11.txt
```
2. Add the named module `HR eID` to NSS module database with `PKCS #11` implementation libfile
```bash
modutil \
-dbdir sql:$HOME/.pki/nssdb \
-add "HR eID" -libfile /usr/lib/akd/eidmiddleware/pkcs11/libEidPkcs11.so \
-mechanisms FRIENDLY \
-force
```
Flag `-mechanisms FRIENDLY` is required to work on Chromium/Chrome,
check [here](https://bugs.chromium.org/p/chromium/issues/detail?id=42073#c76) for details.
Alternative path for newer versions seems to be ``/usr/lib/akd/certiliamiddleware/pkcs11/libEidPkcs11.so`` so try changing path if this is not working for you.
3. Check whether `HR eID` is added to NSS db
```bash
modutil -dbdir sql:$HOME/.pki/nssdb/ -list
```
4. Turn on Client and Signer apps.
## Identification
1. Go to [gov.hr](https://gov.hr) and login with eOsobna option
- Chrome:
- Firefox:
## Signing documents
To sign documents using `LibreOffice` go to
```
LibreOffice > Tools > Options > Security > Certificate... > Select NSS path
```
and navigate to folder `$HOME/.pki/nssdb` and press OK and restart LibreOffice. Go to
```
File > Digital Signatures > Digital Signatures... > Sign Document...
```
and pop-ups for Signature/Identification will appear.
## Debugging
Inspect the content of eidmiddleware:
```bash
$ tree /usr/lib/akd/eidmiddleware/
/usr/lib/akd/eidmiddleware/

I use FER (university usb card reader) ACR38U-A1.
```bash
$ modutil -dbdir sql:$HOME/.pki/nssdb/ -list

## Firefox supports UI to add certificates and secured devices
Download and import manually certificates to Firefox
- `/usr/lib/akd/eidmiddleware/certificates/*` (Firefox > View Certificates > Import)
- `/usr/lib/akd/eidmiddleware/pkcs11/libEidPkcs11.so` (Firefox > Security Devices > Load)
