Pipeline 1 linear · 0 branches

Why use A → B → C?

A pipeline feeds each result directly into the next compatible converter. Use one when the destination needs an intermediate representation or when you want to inspect and normalize that middle format.

JSON → CSV → XLSX turns records into rows before building a workbook.
Markdown → HTML → DOCX resolves markup before creating a document.
SVG → PNG → PDF intentionally flattens vector artwork before placing it on a page.

Only type-compatible next steps are offered. Lossy steps are marked before you run them.

About this conversion

How to convert Plain text to Binary OpenPGP message

Before you start

Paste Plain text content or drop a matching file.

Accepted: .txt · text/plain

Paste valid Plain text content, choose files, or drag them onto the drop zone.
Confirm the detected format and adjust the available settings. Mixed-format batches are flagged before conversion.
Select “Convert on this device.” Produces a downloadable Binary OpenPGP message file with the correct extension and MIME type.

How this converter behaves

OpenPGP.js parses packets and performs requested encryption, decryption, or key serialization entirely in memory; secret options are omitted from presets.

What happens to your data?

The conversion engine runs in this browser tab. OmniCastConverter has no upload API and never sends your content, file name, or converted result to a server.

Fidelity and limitations

This route is classified as lossless. The converter preserves meaning and structure supported by both formats.

OpenPGP protects message confidentiality or authenticity only when keys, passwords, fingerprints, identities, and trust are managed correctly. Secret material is omitted from presets; password fields remain in memory unless the user explicitly saves one to the separate encrypted device vault.

The “Use example” action in the workbench loads this exact input. Produces a downloadable Binary OpenPGP message file with the correct extension and MIME type.
