Add a mechanism to control the sticky cookie value

jbdoumenjou commented 3 years ago

What does this PR do?

Add a mechanism to format the sticky cookie value. It introduces a CookieValue interface to allow implementations to control the sticky cookie value.

There are several implementations available:

RawValue: no operation - keep the cookie value as it is. (used by default)
HashValue: hash the cookie value with a fast hash algorithm.
AESValue: ciphers the cookie value with an AES algorithm.
FallbackValue: try to apply a value transformation and fallback to another. Useful to migrate from one value to another.

Motivation

This PR is inspired by #184 and #203 and provides a flexible way to manage the cookie value and some basic implementations.

closes #184 closes #203

I wish that you would keep our commits as we sent them so that the git history reflects the effort that both @cognusion and I put into this.

By squashing them you discard all authorship information.

The 2 PRs were not compatible and the work to merge them was more important than creating a new PR.

The 2 PRs are referenced in the PR description, and you are flagged as co-author of this PR.

And when I will merge, I will set you as co-author.

In all cases, the commits in a PR are always squashed when we merge.

I am :100: ok with this, philosophically. I have not reviewed the commit for technical merits.

Please may I know when this will be part of a release? Is there way to get notified?
