## README

# bosh-davcli

A CLI utility the BOSH Agent uses for accessing the [DAV blobstore](https://bosh.io/docs/director-configure-blobstore.html). 

Inside stemcells this binary is on the PATH as `bosh-blobstore-dav`.

### Developers

To update dependencies, use `gvt update`. Here is a typical invocation to update the `bosh-utils` dependency:

```
gvt update github.com/cloudfoundry/bosh-utils
```

### Run tests

You can run the unit test with `ginkgo` as follows.

```
ginkgo -r -race -progress -mod vendor .
```

# Pre-signed URLs

The command `sign` generates a pre-signed url for a specific object, action and duration:

`bosh-davcli <objectID> <action: get|put> <duration>`

The request will be signed using HMAC-SHA256 with a secret provided in configuration.

The HMAC format is:
`<HTTP Verb><Object ID><Unix timestamp of the signature time><Unix timestamp of the expiration time>`

The generated URL will be of format:

`https://blobstore.url/signed/object-id?st=HMACSignatureHash&ts=GenerationTimestamp&e=ExpirationTimestamp`
