CA Key erzeugen
openssl ecparam -genkey -name prime256v1 | openssl ec -aes256 -out s77-nerdschloss-ca.key
CA Cert erzeugen (10 Jahre gültig; default: 30 Tage)
openssl req -new -x509 -sha256 -key s77-nerdschloss-ca.key -subj "/C=DE/ST=BW/L=Offenburg/CN=gleis0.section77.localdomain" -out s77-nerdschloss-ca.crt -days 3650
Nerdschloss Key (Server) erzeugen
openssl ecparam -name prime256v1 -genkey -noout -out nerdschloss.gleis0.section77.localdomain.key
Nerdschloss CSR erzeugen
openssl req -new -sha256 -key nerdschloss.gleis0.section77.localdomain.key -subj "/C=DE/ST=BW/L=Offenburg/CN=nerdschloss.gleis0.section77.localdomain" -out nerdschloss.gleis0.section77.localdomain.csr
Nerdschloss Cert (Server) mit CA signieren
openssl x509 -req -in nerdschloss.gleis0.section77.localdomain.csr -CA s77-nerdschloss-ca.crt -CAkey s77-nerdschloss-ca.key -CAcreateserial -out nerdschloss.gleis0.section77.localdomain.crt -days 720 -sha256
Signiere CSR von $Mitglied
openssl x509 -req -in foo\@bar.de.csr -CA s77-nerdschloss-ca.crt -CAkey s77-nerdschloss-ca.key -CAcreateserial -out foo\@bar.de.crt -days 720 -sha256
Client fingerprints (für den ssl_client_fingerprint FP_Block in der nginx.conf benötigt)
openssl x509 -in foo\@bar.de.crt -noout -fingerprint | sed 's/SHA1\ Fingerprint=//;s/://g' >> fingerprints
