Basic with Redis

Basic authentication with Redis

Basic authentication is a simple protocol that uses the HTTP headers and the browser to authenticate users. User credentials are sent to the server in the header Authorization with user:password base64 encoded:

Authorization: Basic dXNlcjpwYXNzd29yZA==

It is secure as long as the communication to the server is encrypted (with SSL for example).

On the server side, you have to provide a user store for Datashare. For now we are using a Redis data store.

So you have to provision users. The passwords are sha256 hex encoded. For example using bash:

$ echo -n bar | sha256sum
fcde2b2edba56bf408601fb721fe9b5c338d10ee429ea04fae5511b68fbf8fb9  -

Then insert the user like this in Redis:

$ redis-cli -h> set foo '{"uid":"foo", "password":"fcde2b2edba56bf408601fb721fe9b5c338d10ee429ea04fae5511b68fbf8fb9", "groups_by_applications":{"datashare":["local-datashare"]}}'

If you use other indices, you'll have to include them in the group_by_applications, but local-datashare should remain. For exammple if you use myindex:

$ redis-cli -h> set foo '{"uid":"foo", "password":"fcde2b2edba56bf408601fb721fe9b5c338d10ee429ea04fae5511b68fbf8fb9", "groups_by_applications":{"datashare":["myindex","local-datashare"]}}'

Then you should see this popup:


Here is an example of launching Datashare with Docker and the basic auth provider filter backed in Redis:

docker run -ti ICIJ/datashare --mode SERVER \
    --batchQueueType REDIS \
    --dataSourceUrl 'jdbc:postgresql://postgres/datashare?user=<username>&password=<password>' \
    --sessionStoreType REDIS \
    --authFilter org.icij.datashare.session.BasicAuthAdaptorFilter \
    --authUsersProvider org.icij.datashare.session.UsersInRedis
