CAcert OAuth2 / OpenID Connect IDP
This repository contains an implementation for an identity provider. ORY Hydra is used for the actual OAuth2 / OpenID Connect operations. The implementation in this repository provides the end user UI components that are required by Hydra to allow login and consent.

Setup
Certificates
You need a set of certificates for the IDP. You can use the Test CA created by
the setup_test_ca.sh
script from the CAcert developer
setup repository like this:
-
create signing requests
mkdir certs cd certs openssl req -new -newkey rsa:3072 -nodes \ -keyout idp.cacert.localhost.key \ -out idp.cacert.localhost.csr.pem \ -subj /CN=idp.cacert.localhost \ -addext subjectAltName=DNS:idp.cacert.localhost,DNS:login.cacert.localhost cp *.csr.pem $PATH_TO_DEVSETUP_TESTCA/
-
Use the CA to sign the certificates
pushd $PATH_TO_DEVSETUP_TESTCA/ openssl ca -config ca.cnf -name class3_ca -extensions server_ext \ -in idp.cacert.localhost.csr.pem \ -out idp.cacert.localhost.crt.pem -days 365 popd cp $PATH_TO_DEVSETUP_TESTCA/idp.cacert.localhost.crt.pem .
-
Copy CA certificate for client certificates
openssl x509 -in $PATH_TO_DEVSETUP_TESTCA/class3/ca.crt.pem \ -out client_ca.pem
Configure IDP
The Identity Provider application (IDP) requires a strong random key for its CSRF cookie. You can generate such a key using the following openssl command:
openssl rand -base64 32
Use this value to create idp.toml
:
[security]
csrf.key = "<32 bytes of base64 encoded data>"
Start
Now you can start the IDP:
make
go run cmd/idp.go
Translations
This application uses go-i18n for internationalization (i18n) support.
The translation workflow needs the go18n
binary which can be installed via
go install github.com/nicksnyder/go-i18n/v2/goi18n
To extract new messages from the code run
goi18n extract .
Then use
goi18n merge active.*.toml
to create TOML files for translation as translate.<locale>.toml
. After
translating the messages run
goi18n merge active.*.toml translate.*.toml
to merge the messages back into the active translation files. To add a new language you need to add the language code to the languages configuration option (default is defined in the configmap in cmd/idp.go).
