V tomto článku sa dozviete, ako nastaviť vlastnú autoritu súkromných certifikátov podporovanú zariadením Nitrokey HSM. Táto certifikačná autorita nemá žiadnu automatizáciu a nie je v skutočnosti škálovateľná. V prípade automatizácie a škálovateľnosti sa môžete odvolať na iné open source projekty.
Výber kryptografických algoritmov¶
Budem predpokladať, že ste rovnako paranoidní ako ja, takže na generovanie súkromných kľúčov použijem nasledujúci príkaz:
pkcs11-tool -l --keypairgen --key-type EC:secp384r1 --label root
Ak ste však menej paranoidní ako ja, môžete si pokojne vybrať nasledujúce možnosti:
pkcs11-tool -l --keypairgen --key-type EC:secp256r1 --label root
pkcs11-tool -l --keypairgen --key-type rsa:4096 --label root
Podobne budem v tomto článku používať algoritmus sha512, ale pokojne možno použiť aj sha256.
Príprava na spustenie¶
Na začiatku je potrebné vybrať adresár na uloženie 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
Nainštalujte potrebné nástroje:
# Arch Linux
pacman -S community/opensc community/libp11
# Ubuntu
sudo apt-get install opensc gnutls-bin
Pre Windows si stiahnite oficiálne Vydanie OpenSC a uistite sa, že ste nainštalovali p11tool podľa popisu. Pomocou PowerShellu by mala byť väčšina príkazov identická, pokiaľ sa oba nástroje a ich binárne súbory nachádzajú vo vašom PATH.
Vytvorenie koreňovej certifikačnej autority¶
Začneme vygenerovaním súkromného kľúča pre certifikačnú autoritu priamo v HSM Nitrokey. To nám umožní súkromný kľúč v budúcnosti používať, ale nie pristupovať k nemu.

Overte, či sa sprostredkovateľský certifikát overuje podľa koreňového certifikátu.
$ openssl verify -CAfile ../certs/root.crt ../intermediate/certs/intermediate.crt
../intermediate/certs/intermediate.crt: OK
Vytvorenie súboru reťazca certifikátov:
cat ../intermediate/certs/intermediate.crt ../certs/root.crt > ../intermediate/certs/chain.crt
Teraz máte k dispozícii certifikačnú autoritu podporenú HSM.
Podpísať certifikát servera¶
Teraz, keď máte autoritu certifikátov, by ste pravdepodobne chceli vedieť, ako ju používať.
Vytvorte CSR bežným spôsobom pre vašu aplikáciu. Správne vytvorenie certifikátu vrátane SAN pre vašu konkrétnu aplikáciu je mimo rozsahu tohto dokumentu.
Potrebujeme zistiť plne kvalifikovaný URI PKCS#11 pre váš súkromný kľúč:
