## AI overview

The article reviews Himitsu 0.9, a Linux secret storage manager that stores passwords and other secrets with associated metadata. It highlights the new hiprompt-gtk GTK4 prompter, implemented in Hare, and notes that Himitsu and its cryptographic dependencies have not been independently audited.

## Source excerpt

Last week, Armin and I worked together on the latest release of Himitsu, a "secret storage manager" for Linux. I haven't blogged about Himitsu since I announced it three years ago, and I thought it would be nice to give you a closer look at the latest release, both for users eager to see the latest features and for those who haven't been following along.1 A brief introduction: Himitsu is like a password manager, but more general: it stores any kind of secret in its database, including passwords but also SSH keys, credit card numbers, your full disk encryption key, answers to those annoying "security questions" your bank obliged you to fill in, and so on. It can also enrich your secrets with arbitrary metadata, so instead of just storing, say, your IMAP password, it can also store the host, port, TLS configuration, and username, storing the complete information necessary to establish an IMAP session. Another important detail: Himitsu is written in Hare and depends on Hare's native implementations of cryptographic primitives - neither Himitsu nor the cryptography implementation it depends on have been independently audited. So, what new and exciting features does Himitsu 0.9 bring to the table? Let me summarize the highlights for you. A new prompter The face of Himitsu is the prompter. The core Himitsu daemon has no user interface and only communicates with the outside world through its IPC protocols. One of those protocols is the "prompter", which Himitsu uses to communicate with the user, to ask you for consent to use your secret keys, to enter the master password, and so on. The prompter is decoupled from the daemon so that it is easy to substitute with different versions which accommodate different use-cases, for example by integrating the prompter more deeply into a desktop environment or to build one that fits better on a touch screen UI like a phone. But, in practice, given Himitsu's still-narrow adoption, most people use the GTK+ prompter developed upstream. U
