# create the tables
CREATE KEYSPACE "ragna"  WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1};
CREATE TABLE ragna.blocks (cid ascii, sha256 blob, size int, enckey blob, nonce blob, pinned boolean, PRIMARY KEY(cid));

# start the ipfs daemon
# make sure you edit the config to suit your needs
$ ipfs daemon

example:

  # POST(upload) a file with namespace `example-ns` and filename `b`
  $ echo 'its working!' | curl -XPOST -d@- -s localhost:9122/io/extample-ns/b?pin=true

  .. from the log we can get the cid of the ipfs object
  INFO[0001] setting extample-ns:b                        
  INFO[0002]   key: extample-ns:b creating block cid: QmVDVooXihvM394UPmcUVAk8NTnLJ4yfdJgfB2n46wjoDw [pin: true], size 12, took 18 
  INFO[0001] removing previous blocks [] 

  # cat the data in ipfs, check that is encrypted
  $ ipfs cat QmVDVooXihvM394UPmcUVAk8NTnLJ4yfdJgfB2n46wjoDw
