A Bit More About the New Joyent Cloud API:

To solve this problem with SmartDataCenter, we’re introducing the HTTP Signature authentication scheme, which is already released as open source. The HTTP Signature scheme allows for digital signatures to be leveraged as your credentials, and does not imply any particular key management scheme. It should be suitable for just about any REST API out there, so we’re certainly hoping if you’re an API vendor you take a look at it, but rather than jump into the technical details of the spec itself, I thought it would be interesting to show you some CLI candy, so lets walk through some examples.
