Replace <your-cid> with the actual CID you received earlier.Medium

Access via IPFS Desktop: If you're using IPFS Desktop, you can also share the file directly through the application interface.

🔐 Encrypting Your File Before Uploading

To ensure privacy, you can encrypt your file before uploading it to IPFS:

Install GPG: Set up GPG (GNU Privacy Guard) on your system.mycoralhealth.medium.com

Generate a Key Pair: Create a public/private key pair for encryption and decryption.

Encrypt the File: Use the recipient's public key to encrypt your file:

Upload the Encrypted File: Add the encrypted file to IPFS as described above.mycoralhealth.medium.com+1Medium+1

Share the CID: Provide the CID of the encrypted file to the recipient. They can decrypt it using their private key.

⚠️ Important Considerations

File Persistence: Files on IPFS are stored as long as there are nodes (computers) pinning them. To ensure your file remains accessible, consider pinning it using services like Pinata or Infura.Pinata Help Center

Privacy: By default, files on IPFS are public. Always encrypt sensitive data before uploading.

File Size: Large files can take time to upload and retrieve, depending on network speed and node availability.
