Sertifikātu iestādes izveide#

(Nitrokey Pro 2 - Linux)

Šajā rakstā ir parādīts, kā iestatīt savu privāto sertifikātu iestādi, ko atbalsta Nitrokey HSM. Šai sertifikātu iestādei nav automatizācijas un tā nav īsti mērogojama. Automatizācijas un mērogojamības ziņā var atsaukties uz citiem atvērtā koda projektiem.

Izvēlieties kriptogrāfijas algoritmus#

Es esmu gatavojas pieņemt, ka jūs esat tikpat paranoisks kā es, tāpēc es izmantošu šādu komandu, lai ģenerētu privātās atslēgas:

pkcs11-tool -l --keypairgen --key-type EC:secp384r1 --label root

Bet, ja esat mazāk paranoisks nekā es, varat droši izvēlēties šādas iespējas:

pkcs11-tool -l --keypairgen --key-type EC:secp256r1 --label root
pkcs11-tool -l --keypairgen --key-type rsa:4096 --label root

Tāpat šajā rakstā izmantošu sha512 algoritmu, taču droši var izmantot arī sha256.

Gatavošanās uzsākšanai#

Vispirms ir jāizvēlas direktorijs, kurā glabāt savu CA.

pki_dir=/opt/certificate-authority
mkdir $pki_dir
cd $pki_dir
mkdir certs config crl newcerts intermediate intermediate/certs intermediate/crl intermediate/csr intermediate/newcerts
touch index.txt intermediate/index.txt
cd config

Uzstādiet nepieciešamos rīkus:

# Arch Linux
pacman -S community/opensc community/libp11

# Ubuntu
sudo apt-get install opensc gnutls-bin

Windows operētājsistēmai lejupielādējiet oficiālo OpenSC versiju un pārliecinieties, ka esat instalējis p11tool, kā aprakstīts. Izmantojot PowerShell, lielākajai daļai komandu vajadzētu būt identiskām, ja vien abi rīki un to binārās datnes atrodas jūsu PATH.

Saknes sertifikātu iestādes izveide#

Sākam ar sertifikātu iestādes privātās atslēgas ģenerēšanu tieši Nitrokey HSM. Tas ļauj mums izmantot privāto atslēgu nākotnē, bet ne piekļūt tai.
