Show HN: Shrouded, secure memory management in Rust
Hi HN!<p>I've been building a project that handles high-value credentials in-process, and I wanted something more robust than just zeroing memory on drop. A comment on a recent Show HN[0] made me realize that awareness of lower-level memory protection techniques might not be as widespread as I thought.<p>The idea here is to pull out all the tools in one crate, with a relatively simple API. * mlock/VirtualLock to prevent sensitive memory from being swapped (eg the KeePass dump) * Core dump exclusion using MADV_DONTDUMP on Linux & Android * mprotect to minimize exposure over time * Guard pages to mitigate under/overflows<p>After some battle testing, the goal here is to provide a more secure memory foundation for things like password managers and cryptocurrency wallets.<p>This was a fun project, and I learned a lot - would love any feedback!<p>[0] - <a href="https://news.ycombinator.com/item?id=47073430">https://news.ycombinator.com/item?id=47073430</a>
Shrouded is a technically sound utility addressing a critical niche in memory security for Rust developers, but it currently presents as an open-source project rather than a commercial startup. While the problem it solves is relevant to high-growth sectors like fintech and crypto, there is no evidence of a business model, team depth, or significant market traction.
