HTTP Proxy^BETA

The SecretHub HTTP Proxy adds a RESTful interface to the SecretHub Client. Apps can this way still use SecretHub, without having to directly include the client as a binary dependency.

You can configure it with a SecretHub credential at start, thereby removing the need of passing it in on every request.

SecretHub is a developer tool to help you keep database passwords, API tokens, and other secrets out of IT automation scripts.

A note on security

The SecretHub HTTP Proxy opens up the configured SecretHub account over HTTP. This moves the responsibility of securing your secrets to the domain of network security, which comes with its own risks. So use this with caution and make sure the credential you pass in only has access to only those secrets it needs.

It is recommended to create a service account, tightly control it with access rules, and use the service credential instead of your own SecretHub account.

secrethub service init my-org/my-repo --permission read --desc my-app

Installation

Binary

Download and extract the latest release of the SecretHub HTTP Proxy. Start it with your SecretHub credential:

./secrethub-http-proxy -C $(cat ~/.secrethub/credential) -p 8080

If upon signup you've chosen to lock your credential with a passphrase, you will get prompted for your passphrase.

Docker

You can also run the proxy as a Docker container. Assuming you have a SecretHub credential stored in the default $HOME/.secrethub location, you can run it with the credential mounted as a volume:

docker run -p 127.0.0.1:8080:8080 --name secrethub -v $HOME/.secrethub:/secrethub secrethub/http-proxy

You can also pass in the credential as an environment variable:

docker run -p 127.0.0.1:8080:8080 --name secrethub -e SECRETHUB_CREDENTIAL=$(cat $HOME/.secrethub/credential) secrethub/http-proxy

If upon signup you've chosen to lock your credential with a passphrase, run the container with -it to get prompted for your passphrase.

docker run -it -p 127.0.0.1:8080:8080 --name secrethub -e SECRETHUB_CREDENTIAL=$(cat $HOME/.secrethub/credential) secrethub/http-proxy

Alternatively, the passphrase can be sourced from the SECRETHUB_CREDENTIAL_PASSPHRASE environment variable.

Usage

With the proxy up and running, you can perform the following HTTP requests:

/v1beta/secrets/raw/:path

Example:

/v1beta/secrets/raw/my-org/my-repo/my-secret

GET

Returns the secret contents as bytes.

POST

Creates or updates a secret. Expects the secret contents as bytes.

DELETE

Deletes the entire secret and its history.
