MerkleShare

A no-brainer pastebin on IPFS - think distributed http://sprunge.us

Why this if there's `ipfs add`?

Good question! ipfs add currently doesn't support showing a full link, let alone xclip-compatible output - the user has to select the hash, paste it in a browser and manually add the rest of their preferred IPFS link format.

Installation

merkleshare is available through PyPI:

$ pip install merkleshare

But if you want, you can install it directly from the repo:

$ pip install git+https://github.com/drozdziak1/merkleshare

Requirements

In order for MerkleShare to work, you need to bring up a local IPFS node using ipfs daemon.

Usage

A typical stdin pipe situation:

$ echo "Hello, world" | mersh -t gateway
https://ipfs.io/ipfs/QmaMLRsvmDRCezZe2iebcKWtEzKNjBaQfwcu7mcpdm8eY2

How about some file input?

$ echo "Hello, friends." > file.txt
$ mersh file.txt
/ipfs/QmZRyLRgWiXN2Zks6rjH5jPYQzbWj3BYTWERa9m7QQc3kW

Or maybe you only need the hash? No problem:

$ echo "Rollin' with the hash\!" | mersh -t hash

Got security needs? You'll be happy to know that MerkleShare supports Fernet encryption (via the cryptography module):

$ echo "Lizard people live at the edge of flat earth" | mersh -e
/ipfs/QmcXM8gCqeJA2qjnVmFYkFFc2sMjDvT21p8UwGBwzWxva8/#fT7jn4eDJLgHcM3wva4KS4eUMyJ19zuxRJhy5Lp5xwZsVzA4Q6AzoEEEZxUt
                                                     # `----------------------------------------------------------'
                                                     #        Your data is guarded by a disposable secret

It's not possible to reach your data without the secret, which is only present in the link...

$ ipfs cat /ipfs/QmcXM8gCqeJA2qjnVmFYkFFc2sMjDvT21p8UwGBwzWxva8

...but if you do have it then retrieving your stuff with MerkleShare becomes about as easy as it gets:

$ mersh -d /ipfs/QmcXM8gCqeJA2qjnVmFYkFFc2sMjDvT21p8UwGBwzWxva8/#fT7jn4eDJLgHcM3wva4KS4eUMyJ19zuxRJhy5Lp5xwZsVzA4Q6AzoEEEZxUt

Features

Read from stdin or a specified file
Only the link gets printed to stdout, everything else is stderr - effortlessly pipe it to your favourite clipboard manager!
Seamless data encryption
Output the link in the format you need:
- Regular: /ipfs/<hash>
- Gateway: https://ipfs.io/ipfs/<hash> - great for sharing links with non-IPFS friends
- Local: http://localhost:8080/ipfs/<hash>
- Bare: <hash>
Optional static WebUI (Enabled with the -g flag)

Planned Features

Built-in clipboard support
Pure Python IPFS backend (once py-ipfs is ready)
Binary blob support for WebUI uploads
