As commented, the secret or any other sensitive information should never been part of a Git repository.

To illustrate that, see ubuntudesign/git-mirror-service, a simple WSGI server to create a mirror of a remote git repository on another remote.
It does include the step:

Optional secret
By default the server is unsecured - anyone who can access it can use it to mirror to repositories that the server has access to.

To prevent this, you can add a secret:

QUESTION

Change PouchDB's rev algorithm to use a blockchain / hashchain pattern

Asked 2017-Dec-07 at 18:39

Is it within reason to change CouchDB / PouchDB's revision algorithm 'under the hood' to use a blockchain style 'hashchain' such that the _rev of every doc is the result of a hash of it's previous revisions?

Such a model would help preserve the integrity of revisions; in a distributed network for example it could essentially be the basis of an immutable history for your entire db.

In fact, the _rev is a deterministic hash over the document and all of its revisions, at least for CouchDB. It's also using the previous _rev, so you basically get a deterministic hash if you make the same sequence of updates to a document.

Unfortunately, it's an MD5 hash, so it isn't really suitable for security-related stuff.

AFAIK, the actual value of the _rev is never checked, only the part before the dash must be numeric. So you could write a PouchDB plugin that changes the _rev generation and also checks the integrity of the _rev value on every update.
