This report outlines safe methods for accessing Autodesk AutoCAD 2023

For projects exceeding 1GB, the user must pivot to a more aggressive, though still free, strategy: client-side encryption paired with a commodity host. Services like Google Drive or MEGA (which offers 20GB free) provide robust transport encryption (TLS 1.3), but server-side access is technically possible. To achieve true "secure transfer," one must encrypt the AutoCAD file before upload. The free, open-source utility 7-Zip (or its command-line equivalent) is the ideal partner. By right-clicking a collection of .dwg files and selecting 7-Zip > Add to archive, the user can choose AES-256 encryption—the same standard used by the U.S. government for classified documents. Creating a self-extracting archive (.exe or .7z) with a 32-character password ensures that even if the free cloud host suffers a breach, the AutoCAD data remains mathematically indecipherable. The receiving party only needs the same free password to decrypt. This two-step method (compress, encrypt, upload) turns any free cloud provider into a secure vault.

Step 3 – Choose a secure free transfer tool (from Part 3)

• For files under 5 GB: Tresorit Send or Internxt Send.
• For 5-10 GB: Send Anywhere.
• For 10+ GB (rare with RAR compression, but possible): OnionShare or self-hosted via SFTP (e.g., using free Oracle Cloud trial then delete after).

5. OnionShare (100% free, open-source, no size limit)

• Method: Direct, peer-to-peer via Tor network. You host the file on your machine.
• Security: Extreme – recipient downloads directly from you. No third party.
• Use case: Sending a 20 GB AutoCAD folder with drawings, XREFs, and point clouds.
• Downside: Requires both users to have OnionShare; slower due to Tor.

If you want, I can: create exact 7-Zip command lines, show how to generate SHA-256 checksums, or give step-by-step for Syncthing/OnionShare. For files under 5 GB: Tresorit Send or Internxt Send

1. Run AUDIT and -PURGE to clean the DWG.
2. Use ETRANSMIT to package dependencies.
3. Compress with 7-Zip (Ultra, .7z).
4. Upload to Tresorit Send (5GB free) or Mega.nz (20GB free).
5. Share the decryption key/password via a separate channel (e.g., SMS or phone call, not the same email).
