+
+
+ HTTP ProxyBETA
+
+
+[][godoc]
+[][circleci]
+[][goreportcard]
+[][latest-version]
+[][discord]
+
+The SecretHub HTTP Proxy adds a RESTful interface to the [SecretHub Client](https://github.com/secrethub/secrethub-go).
+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](https://secrethub.io) 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](https://secrethub.io/docs/reference/service-command/), tightly control it with [access rules](https://secrethub.io/docs/reference/acl-command/), 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](https://github.com/secrethub/secrethub-http-proxy/releases/latest) of the SecretHub HTTP Proxy. Start it with your SecretHub credential:
+
+```
+./secrethub-http-proxy -C $(cat ~/.secrethub/credential) -p 8080
+```
+
+If upon signup you've chosen to lock your credential with a passphrase, you will get prompted for your passphrase.
+
+### Docker
+
+You can also run the proxy as a [Docker container](https://hub.docker.com/r/secrethub/http-proxy).
+Assuming you have a SecretHub credential stored in the default `$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.
+
+## BETA
+
+This project is currently in beta and we'd love your feedback! Check out the [issues](https://github.com/secrethub/secrethub-http-proxy/issues) and feel free to suggest cool ideas, use cases, or improvements.
+
+Because it's still in beta, you can expect to see some changes introduced. Pull requests are very welcome.
+
+## Terraform State Backend
+
+For those of you using [Terraform](https://www.terraform.io), the SecretHub HTTP Proxy can function as a [Terraform Backend](https://www.terraform.io/docs/backends/index.html) for your `.tfstate`.
+Read more about this on our [blog post]().
+
+## Development
+
+Get the source code:
+
+```
+git clone https://github.com/secrethub/secrethub-http-proxy
+```
+
+To build the binary from source, use:
+
+```
+make build
+```
+
+To build the Docker image from scratch, you can use:
+
+```
+docker build -t secrethub-http-proxy .
+```
