How to verify Terraform provider h1 locally

Question

I've patched and released an internal fork of F5 Bigip based on BigIP one, which is released on internal network mirror. Important note: I build the provider on Windows, I have no choice to build this on a Linux platform. I build provider for both Windows and Linux on this machine

I face two issues:

Linux Provider binary is not executable

Description

Linux provider zip package contains provider file which is not executable

Bypass

1. Run chmox +x .terraform/providers/f5networks/bigip/terraform-provider-XXXXX in project root
2. Run terraform init -upgrade
3. Run terraform plan
4. Works

Question

How to make this provider executable after build time ?

Compute h1 checksum

Description

To deploy this on our static mirror, we need to compute a h1 of the provider. Terraform uses this lib to compute h1: https://pkg.go.dev/golang.org/x/mod/sumdb/dirhash

But, when I run the suggestion command: find . -type f | sort | sha256sum | base64 and then run terraform init -upgrade, Terraform says checkum do not match

Bypass

1. Generate zh checksum (sha256sum over .zip), put id in 1.2.3.json
2. Run terraform init -upgrade
3. Grab h1 from .terraform.lock.hcl and copy it to 1.2.3.json and remove zh
4. Run terraform init -upgrade
5. Run terraform plan
6. Works

Question

Which command should I run to get h1 from the command line to directly copy into json file ?
