kt d6ed06cf15 internal/providers/aws: Refactor deprecated crypto/elliptic APIs to crypto/ecdh (#8395)
Following SA1019 deprecation warnings in Go 1.21+, the legacy curve.ScalarBaseMult
and curve.IsOnCurve calls for NIST curves (like P256) are substituted with
their crypto/ecdh standard equivalents. Tests continue to parse and verify AWS V4a
signatures equivalently under the new module constraints.

Anders Eknert d3f34a3387 Modernize analyzer fixes (#7965)
Have done this some time in the past, but there was a few
new issues this would highlight now that we're on Go 1.24.

Mostly:
- Use `b.Loop()` in benchmarks
- Use `strings.SplitSeq` where possible
- Remove `omitempty` tag for types that can't be empty

Anders Eknert 8ba08ac80c Apply modernize linter fixes (#7599)
Following up on #7566, and now applying the more exciting
modernizations. fmt.Appendf was new to me! But especially
the contains checks are so much better IMHO. I have reviewed
all changes myself and did a few manual changes where it
became obvious that things could be improved a little further.

(the modernize analyzer still has some issues running against
OPA, and I have manually worked around those for the time being)

Anders Eknert e43ef0a979 Use any in place of interface{} (#7566)
Earlier this evening I tried to run the Go
[modernize](https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize)
analyzer on OPA. That didn't go as planned:

- https://github.com/golang/go/issues/73661
- https://github.com/golang/go/issues/73663

While we wait for that to be fixed, I figured an old-fashioned
search-and-replace across the repo may work for at least the
`interface{}` to `any` conversion. That should help make it easier
to see the other fixes as applied by the modernize tool once it has
had those issues resolved.

Anders Eknert afb30d3f9d Add gocritic linter, fix a bunch of stuff (#7377)
Brace yourselves! For there are many touched files here. No changes
in semantics however.

Spent a long time trying out the various optional rules gocritic
provides, and settled for a few of them. There are more I really
like, but that would take many hours to address across the codebase.

Perhaps others find gocritic too pedantic? If so, we can merge the
fixes without enabling the rule.

Anders Eknert 622434d113 Add util.Keys and util.KeysSorted (#7285)
And use them to reduce imperative boilerplate throughout
the codebase.

Additionally, replace use of sort.Slice with slices.SortFunc
which is more efficient since it is generic and as such avoids
allocations related to `interface{}` casts.

Also a few performance-related minor fixes, but not the main
theme of this PR.

Prasanth Jayachandran 7f5e3a9d1e aws: support for Unsigned Payload or provided content sha256 in AWS signing (#6581)
To support uses cases where OPA is used for signing s3 requests whose payload is
not known upfront or payload is big enough (big file upload) to be sent over wire,
this PR adds support for unsigned payloads.

AWS signer has configurable option to use unsigned payload where the
x-amz-content-sha256 is set to "UNSIGNED-PAYLOAD" and is included as part
of signing process. This PR provides an option for unsigned payload if
aws_config.disable_payload_signing is set to true. If payload signing is
disabled, SignV4 method will not compute the content sha from the request body
but instead use "UNSIGNED-PAYLOAD" string literal for x-amz-content-sha256
header during signature computation.

DerGut b626a2c93b Use existing auth plugins with OCIDownloader
This change addresses solutions 2) and 3) of the related issue #5553.
It mainly starts using the (now exposed) `Config.AuthPlugin()` function
of the `rest` package in the `download.OCIDownloader`. This allows it
to use any `HTTPAuthPlugin` that is defined in the `Config.Credentials`
section and makes it much more consistent with behavior of the
`download.Downloader` and potential other uses of the rest package.

Fixes #5553

Jay Wineinger ea39bf35b9 Feat: Add support for AWS Signing Version 4A (#5489)
AWS is rolling out an extension to SigV4 called Signature Version 4A (SigV4A)
which enables signatures that are valid in more than one AWS Region. This is
required for signing multi-region API requests, for example with Amazon S3
Multi-Region Access Points (MRAP). This commit lets OPA use an S3 MRAP as
a bundle source.

The SigV4A implementation used in this commit is a modified version of
internal code from the `aws-sdk-go-v2` project:
https://github.com/aws/aws-sdk-go-v2/tree/93c3f18/internal/v4a

This commit also refactors the existing V4 signing code into a shared
`internal/providers/aws` package that contains both the existing V4 signing
code as well as the V4A signing code added by this PR.

Fixes #5429

Philip Conrad 1d1cb357ae providers/aws: Refactor + Fix 2x Authorization header append issue. (#5475)
This commit refactors the shared AWS Sig v4 signing code, specifically
to prevent the issue behind #5472. The underlying problem for was
that the `"Authorization"` header was being appended *twice* to the
request, but only for the AWS REST plugin, because the value was pulled
twice from the signed headers map.

This was not caught by the unit tests, because the REST plugin's unit
tests all assumed the header was single-valued and canonicalized.

We now explicitly test for that condition in the unit tests, and the
signing code now returns the AWS headers map separately from the value
for the `"Authorization"` header, reducing the potential for this
mistake to happen in the future.

Fixes: #5472

Philip Conrad ed76301eb6 builtins: Add AWS Sig v4 signing builtin. (#5376)
This commit adds initial support for AWS's SigV4 request signing system,
which will allow OPA's existing `http.send` builtin to be used to more
conveniently query cloud resources. It automates away most of the pain
around signing the request headers and body, and is designed to compose
with `http.send` directly.

Internally, this also refactors AWS SigV4 request signing, so that the
signing logic is shared between the builtin and the REST plugin for AWS.

Fixes: #3749
