openssl-cert-gen-template

Clone this repo and follow the instructions for the following:

• Create a root CA pair
• Intermediate CA pair
• Generate & sign client & server certs
• Import server certs in JKS format
• Import CAs into a truststore

This repo structure is created based on this documentation. For detailed explanation on the following steps, please refer the above mentioned docs!

Create root CA pair

When prompted for CN, use "Alfresco Software Inc Root CA" as CN. Root key will be generated at private/ca.key.pem. Root certificate generated can be found at certs/ca.cert.pem

You may also want to provide a valid directory in the openssl.cnf for "dir"

cd openssl-cert-gen-template
openssl genrsa -aes256 -out private/ca.key.pem 4096
openssl req -config openssl.cnf \
      -key private/ca.key.pem \
      -new -x509 -days 7300 -sha256 -extensions v3_ca \
      -out certs/ca.cert.pem
openssl x509 -noout -text -in certs/ca.cert.pem

Create intermediate CA pair

When prompted for CN, use "Alfresco Software Inc Intermediate CA" as CN. Intermediate CA key will be generated at intermediate/private/intermediate.key.pem. Intermediate certificate can be found at intermediate/certs/intermediate.cert.pem

You may also want to provide a valid directory in the openssl.cnf for "dir"

cd intermediate
openssl genrsa -aes256 \
      -out private/intermediate.key.pem 4096
openssl req -config openssl.cnf -new -sha256 \
      -key private/intermediate.key.pem \
      -out csr/intermediate.csr.pem
      
openssl ca -config ../openssl.cnf -extensions v3_intermediate_ca \
      -days 3650 -notext -md sha256 \
      -in csr/intermediate.csr.pem \
      -out certs/intermediate.cert.pem

openssl x509 -noout -text \
      -in certs/intermediate.cert.pem
      
openssl verify -CAfile ../certs/ca.cert.pem \
      certs/intermediate.cert.pem
      
cat certs/intermediate.cert.pem \
      ../certs/ca.cert.pem > certs/ca-chain.cert.pem

Create & sign a client certificate

When prompted for CN, enter CN and email as admin and [email protected] (Alfresco Process Services default userid) respectively

cd intermediate
openssl genrsa -aes256 \
      -out private/admin.key.pem 2048
      
openssl req -config openssl.cnf \
      -key private/admin.key.pem \
      -new -sha256 -out csr/admin.csr.pem
      
openssl ca -config openssl.cnf \
      -extensions usr_cert -days 375 -notext -md sha256 \
      -in csr/admin.csr.pem \
      -out certs/admin.cert.pem
openssl x509 -noout -text \
      -in certs/admin.cert.pem
      
openssl verify -CAfile certs/ca-chain.cert.pem \
      certs/admin.cert.pem

Create & sign a server certificate

When prompted for CN, enter CN as localhost (for localhost apps)

cd intermediate
openssl genrsa -aes256 \
      -out private/localhost.key.pem 2048
      
openssl req -config openssl.cnf \
      -key private/localhost.key.pem \
      -new -sha256 -out csr/localhost.csr.pem
      
openssl ca -config openssl.cnf \
      -extensions server_cert -days 375 -notext -md sha256 \
      -in csr/localhost.csr.pem \
      -out certs/localhost.cert.pem
openssl x509 -noout -text \
      -in certs/localhost.cert.pem
      
openssl verify -CAfile certs/ca-chain.cert.pem \
      certs/localhost.cert.pem

Create a keystore for app server configuration

When prompted for password for the next two steps (export and keystore), use the same password

cd openssl-cert-gen-template
openssl pkcs12 -export -chain \
	-in intermediate/certs/localhost.cert.pem \
	-inkey intermediate/private/localhost.key.pem \
	-out keystore/keystore.p12 \
	-CAfile intermediate/certs/ca-chain.cert.pem
	
keytool -importkeystore \
	-destkeystore keystore/keystore.jks \
	-srckeystore keystore/keystore.p12 \
	-srcstoretype PKCS12

Create a truststore with both root and intermediate CAs

cd openssl-cert-gen-template
keytool -import -alias rootca \
	-file certs/ca.cert.pem \
	-keystore truststore/truststore.jks
	
keytool -import -alias intermediateca \
	-file intermediate/certs/intermediate.cert.pem \
	-keystore truststore/truststore.jks
