Martin Atkins 4d1c6c151b go.mod: go get golang.org/x/crypto@v0.45.0
This is primarily to clear naive security scanner reports for GO-2025-4135,
which is a potential denial of service if attacker-controlled software can
send malformed packets back to OpenTofu through the SSH Agent proxy
channel.

We are not considering this a significant vulnerability for OpenTofu
because the SSH Agent forwarding pattern already assumes that software on
the remote system is trusted not to misuse the keys that are exposed though
the proxy channel.

Due to the Go team's policy of ratcheting upgrades between all of the
golang.org/x/* modules, this also requires upgrading three other modules.
I have reviewed the changes in those, and most appear to not affect
OpenTofu at all. There are some performance improvements to the HTTP2 and
QUIC implementations in x/net, but they don't seem to be a big concern for
us.

OpenSSF Best Practices

OpenTofu is an OSS tool for building, changing, and versioning infrastructure safely and efficiently. OpenTofu can manage existing and popular service providers as well as custom in-house solutions.

The key features of OpenTofu are:

  • Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.

  • Execution Plans: OpenTofu has a "planning" step where it generates an execution plan. The execution plan shows what OpenTofu will do when you call apply. This lets you avoid any surprises when OpenTofu manipulates infrastructure.

  • Resource Graph: OpenTofu builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, OpenTofu builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.

  • Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what OpenTofu will change and in what order, avoiding many possible human errors.
