ChainSafe Files is a cloud platform that lets you upload files to IPFS and Filecoin. The files you upload are encrypted. This tool demonstrates the fact that given enough knowledge about your files, you can actually retrieve them without needing to log in to the ChainSafe Files platform. All you need is the content identifier of your file (cid) and the decryption key. When connected to Files user interface, the key is printed in the console of your browser.

• node v15 or later (get it here)

Currently, the only available command is get.

Required arguments:

• --cid: IPFS content identifier of the file to get. This is available in the "info" menu for each file stored on Files.
• --output: Full local path where the file will be saved once downloaded and decrypted, for example ./my-image.jpg
• --key: Decryption key from ChainSafe Files. This is available in the "info" menu from each file stored on Files.

Optionnal arguments:

• --gateway: IPFS gateway to get the file from. Default: "https://ipfs.io/ipfs/"
