Streams and Data Access

Question

From your blog:
--------------------
Streams provide a natural way to support encrypted data on a blockchain, as follows:

1. One stream is used by participants to distribute their public keys for any public-key cryptography scheme.
2. A second stream is used to publish data, where each piece of data is encrypted using symmetric cryptography with a unique key.
3. A third stream provides data access. For each participant who should see a piece of data, a stream entry is created which contains that data’s secret key, encrypted using that participant’s public key.
   
   Do we have any documentation/steps how to implement this?

Answer 1

We don't have any more detailed documentation than this, and for now all the encryption will happen at the application level. You should be able to use a tool/library like OpenSSL to do most of the heavy lifting for you, so it's mainly a matter of deciding what encryption schemes you wish to use.
