ipfs-file-enc - encrypt file and add to IPFS.

Currently, IPFS does not have an inbuilt content encryption system. Many solutions exist on top. I wanted something easy. This builds on senc.

On the commandline

This tool is command-line based.

Install

Using go get:

go get github.com/Csterkuroi/ipfs-file-enc/ipfs-file-enc

How to encrypt & share

# encrypt with a known key. (256bits)
ipfs-file-enc --key <secret-key> share <path-to-file>

# encrypt with a randomly generated key. will be printed out.
ipfs-file-enc share <path-to-file>

Leave your IPFS node running, or pin this somewhere.

How to download & decrypt

# will ask for key
ipfs-senc download <ipfs-link> <local-destination-dir>

# decrypt with given key.
ipfs-senc --key <secret-key> download <ipfs-link> [<local-destination-dir>]

Will use your local ipfs node, or the ipfs-gateway if no local node is available.

Example

>ipfs-file-enc share index.js
