Function gpgExec

pgp/keysource.go:625–636

gpgExec runs the provided args with the gpgBinary, while restricting it to homeDir when provided. Stdout and stderr can be read from the returned buffers. When the command fails, an error is returned.

(ctx context.Context, homeDir string, args []string, stdin io.Reader)

// buffers. When the command fails, an error is returned.
