# This shell script can be used to create all necessary certificates and Keystores needed in order to
# - successfully perform a TLS handshake between the EVCC (TLSClient) and the SECC (TLSServer) and 
# - install/update a contract certificate in the EVCC.
# 
# This file shall serve you with all information needed to create your own certificate chains.
#
# Helpful information about using openssl is provided by Ivan Ristic's book "Bulletproof SSL and TLS".
# Furthermore, you should have openssl 1.0.2 (or above) installed to comply with all security requirements 
# imposed by ISO 15118. For example, openssl 0.9.8 does not come with SHA-2 for SHA-256 signature algorithms. 
# Some MacOS X installations unfortunately still use openssl < v1.0.2. You could use Homebrew to install openssl. 
# Be aware that you probably then need to use an absolute path for your openssl commands, such as 
# /usr/local/Cellar/openssl/1.0.2h_1/bin/openssl.

# FURTHER REMARKS:
# 1. OpenSSL does not use the named curve 'secp256r1' but the equivalent 'prime256v1'. So this file uses only 'prime256v1'.
# 2. The password used is stored in the file passphrase.txt. In it, you'll find two lines. The first line is used for the -passin option, the second line for the -passout option (especially when dealing with PKCS12 containers). See also https://www.openssl.org/docs/man1.0.2/apps/openssl.html, section "Pass Phrase Arguments"


# 0) Create directories if not yet existing

# 1.2) Create a CSR
#	- new -> -new
#	- certificate signing request -> req
# 	- using the previously created private key from which the public key can be derived -> -key
#	- use the passwort stored in the file to decrypt the private key -> -passin

#	- use the X.509 utility command -> x509
#	- requesting a new X.509 certificate ... -> -req
#	- ... using a CSR file that is located at -> -in
#	- we need an X.509v3 (version 3) certificate that allows for extensions. Those are specified in an extensions file ... -> -extfile
#	- ... that contains a section marked with 'ext' -> -extensions
# 	- self-sign the certificate with the previously generated private key -> -signkey
#	- use the passwort stored in the file to decrypt the private key -> -passin
#	- tell OpenSSL to use SHA-256 for creating the digital signature (otherwise SHA1 would be used) -> -sha256
#	- each issued certificate must contain a unique serial number assigned by the CA (must be unique within the issuers number range) -> -set_serial
#	- save the certificate at the location provided -> -out
# 	- make the certificate valid for 40 years (give in days) -> -days

# Since the intermediate certificates need to be in PEM format when putting them in a PKCS12 container and the resulting PKCS12 file is a binary format, it might be sufficient.

# 	- create a PKCS12 file -> -export
#	- if no private keys are added, e.g. for a truststore that holds only root CA certificates -> -nokeys
# 	- add a private key to the newly created PKCS12 container; must be in PEM format (not DER) -> -inkey
#	- add any certificate (leaf certificate or root certificate); must be in PEM format (not DER) -> -in
#	- add additional certificats (intermediate sub-CA certificates or more root CA certificates); must be in PEM format (not DER) -> -certfile
#	- use AES to encrypt private keys before outputting -> -aes128
#	- passphrase source to decrypt any private keys that are to be imported -> -passin
#	- passphrase to encrypt any outputted private keys with -> -passout
#	- provide the "friendly name" for the leaf certificate, which is used as the alias in Java -> -name
# 	- provide the "friendly name" for CA certificates, which is used as the alias in Java;

# 19) Create truststores for EVCC and SECC. Storing trust anchors in PKCS12 is not supported in Java 8. For creating trusstores we need a Java KeyStore (JKS) and import the DER encoded root CA certificates.
