IronKey, a Los Altos, Ca. company that makes a high-speed encrypted USB flash drive device, has raised $7.9 million in financing.

Of that, $6 million was raised late last year from Leapfrog Ventures and other investors, $500,000 came more recently from debt provider Western Technology. The company also got a $1.4 million government grant for development (see BizJournal story on this company).

The product will begin shipping later this spring.

The devices will cost between $79 to $149, and range between 1 and 4 gigabytes, and as part of the service, passwords and backup files are stored online.
