Sertifitseerimisasutuse loomine#

(Nitrokey HSM 2 - macOS)

See artikkel näitab teile, kuidas luua oma eraõiguslik sertifitseerimisasutus, mille taga on Nitrokey HSM. See sertifitseerimisasutus ei ole automatiseeritud ja ei ole tegelikult skaleeritav. Automatiseerimise ja skaleeritavuse osas võib viidata teistele avatud lähtekoodiga projektidele.

Krüptograafiliste algoritmide valimine#

Eeldan, et olete sama paranoiline kui mina, seega kasutan privaatvõtmete genereerimiseks järgmist käsku:

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

Aga kui te olete vähem paranoiline kui mina, võite julgelt valida järgmised võimalused:

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

Samamoodi kasutan ma käesolevas artiklis kogu aeg sha512 algoritmi, kuid võib julgelt kasutada ka sha256.

Ettevalmistused alustamiseks#

Alustuseks peate valima kataloogi, kuhu oma CA-d salvestada.

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

Paigaldage vajalikud tööriistad:

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

# Ubuntu
sudo apt-get install opensc gnutls-bin

Windowsi jaoks lae alla ametlik OpenSC versioon ja veendu, et sa installeerid p11tool nagu kirjeldatud. PowerShelli kasutades peaks enamik käske olema identsed, kui mõlemad tööriistad ja nende binaarsed failid on sinu PATH sees.

Juursertifikaadi asutuse loomine#

Alustame sertifitseerimisasutuse privaatvõtme genereerimisega otse Nitrokey HSM-is. See võimaldab meil tulevikus kasutada privaatvõtit, kuid mitte sellele juurde pääseda.
