Open PUB on Phone

PUB files often store SSH or other public key text.

• Phone file apps often do not show certificate or key files clearly.
• Certificate files may be PEM text or binary DER data.
• Some files can contain private or deploy-related key material.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.
