Functions

func DownloadAndVerifyFileSync

func DownloadAndVerifyFileSync(ctx context.Context, verifyFunc DownloadVerifier, auditor DownloadAuditor,
	identifier DownloadIdentifier, crlUrl url.URL, finalPath string, maxRetries uint,
	timeout time.Duration) (bool, error)

* Returns: Boolean of whether the data at finalPath is now valid, and any error. It is possible * that err != nil and yet finalPath is valid, so callers should rely on the boolean and merely * log the error as needed.
