Cosign crashes when password input is requested from terminal in Windows

[gjirm]

On Windows when password should be read from terminal, application immediately crashes with the following error:

Enter password for private key:
Error: The handle is invalid.
main.go:46: error during command execution: The handle is invalid.

For example when running these commands:

cosign generate-key-pair
cosign sign --key cosign.key ...

I think it is related to the bug #862 I previously reported.

My environment

• Windows 11 (21H2 - build 22000.318), Windows 10 (21H2 - build 19044.1348)
• cosign v1.4.0
• Window Terminal v1.11.2921.0
  • native cmd.exe
  • PowerShell 7.2.0

@gjirm I wasn't able to reproduce the issue. Would you be able to add a test case to https://github.com/sigstore/cosign/blob/main/test/e2e_test.ps1 that provokes the bug?

@dekkagaijin Unfortunately, I don't know how to add a test case, because it only happens to me if I run the command without entering a password (via a environment variable or via a pipe). See example below for cosign generate-key-pair:

I also have similar issue. I use Windows 10 Pro. I downloaded v1.5.1 version of cosign.
When I run cosign generate-key-pair in PowerShell/cmd i get such thing:

Enter password for private key: Error: The handle is invalid.
main.go:46: error during command execution: The handle is invalid.

When I run the same command in git bash, then bash hangs and I need to kill this command:

$ cosign generate-key-pair -d

Providing password via environment variable resolves this issue.
