I’m excited to announce the first [official release](https://github.com/cryptotronix/hashlet/releases/tag/v0.1.0 "Github Release Page") of the Hashlet software!  The [README](https://github.com/cryptotronix/hashlet/blob/master/README.md) outlines the available commands; see this blog [post](https://cryptotronix.wordpress.com/2013/12/27/hashlet_random_tests/ "External hardware random number generator for the BeagleBone Black") on using the hardware random number generator.

I’m particularly fond of the `offline-verify` feature. This feature allows you to verify a Message Authentication Code (MAC) from the Hashlet without needing the device attached. I’ll blog a short tutorial soon but the expected use case is a situation where a remote server must verify a message sent from a BeagleBone Black.  I’ve tested the software on a BBB running Debian; official Angstrom support will be in the next release.

The next release will be [0.2.0](https://github.com/cryptotronix/hashlet/issues?milestone=2&state=open) which will add a “clone” feature. This feature which allow you to set up two Hashlets, with the same keys, so that they can authenticate each other.

I’m planning on selling the Hashlets on [Tindie](/content/2013/12/30/first-official-hashlet-release/www.tindie.com). Once they are available, I’ll make an announcement here so be sure to subscribe. I will have a limited number available for this first batch.
