Two hash schemes exist: <code>zh:</code> (a legacy scheme tied to zip archives) and <code>h1:</code> (a directory hash of the unpacked provider). Understanding how these are calculated helps when debugging lock file mismatches or verifying providers manually.</p> <h2 id="zh-and-h1-checksums">zh and h1 Checksums</h2> <p>The <code>terraform init</code> command downloads the provider and verifies that it matches one of the checksums in the lock file, then extracts the package into <code>.terraform/providers</code>.</p>https://blog.corneschi.ro/posts/about/Mon, 01 Jan 0001 00:00:00 +0000https://blog.corneschi.ro/posts/about/<div class="d-flex flex-column flex-sm-row align-items-start gap-3 mb-3"> <img src="avatar.jpg" alt="Daniel Corneschi" width="220" height="220" class="rounded-circle" style="flex-shrink: 0"> <div> <p>Hi, I&rsquo;m <strong>Daniel Corneschi</strong>, a Linux systems engineer at <strong>NTT Data</strong>, based in <strong>Romania</strong>.</p> <p>I work on infrastructure: Linux and Unix servers, networks, cloud and the automation that ties them together.
