Creare un keystore per la firma del codice di j4sign

N.B.: Questa procedura non è in alcun modo specifca per j4sign, il keystore ottenuto può essere usato per firmare il codice che si preferisce.

1) Creazione CA (vedere la sezione openssl.conf più sotto per i defaults)

openssl req -config openssl.conf -new -x509 -days 3650 -keyout my-ca.key -out my-ca.crt -outform DER -set_serial 0

2) Creazione struttura per la CA

mkdir -p demoCA/certs
mkdir demoCA/newcerts
touch demoCA/index.txt
echo 01 > demoCA/serial

openssl x509 -in my-ca.crt -inform DER -out demoCA/ca.pem -outform PEM
mv my-ca.key demoCA/ca.key

3) Importazione CA (e creazione keystore; viene richiesta la password del keystore)

keytool -import -keystore .keystore.swsign -file my-ca.crt -alias my-ca

4) Generazione coppia di chiavi

(e creazione keyentry; viene richiesta la password per swsign-rsa; il parametro dname è identico, a parte il CN, ai defaults per la CA specificati in openssl.conf )

keytool -genkeypair -alias swsign-rsa -keyalg rsa -keysize 1024 -validity 365 -keystore .keystore.swsign -dname "CN=test firma, OU=NOME UFFICIO O SOTTOSEZIONE, O=DITTA O ENTE, L=CITTA, ST=STATO, C=IT"

5) Generazione Certificate Signing Request:

keytool -certreq -alias swsign-rsa -file swsign-rsa.csr -keystore .keystore.swsign

6) Firma della csr (vedere in fondo per il file openssl.conf)

openssl ca -config openssl.conf -in swsign-rsa.csr -out swsign-rsa.pem -days 365

7) Conversione in formato DER

openssl x509 -in swsign-rsa.pem -out swsign-rsa.crt -outform DER

8) importazione del certificato nel keystore

keytool -import -keystore .keystore.swsign -file swsign-rsa.crt -alias swsign-rsa
