[ruffiano89]

Required:

1. Create

2. Resolve

3. Update

4. Create: Param (content: object) Returns Content: object

   const cid = await ipfs.dag.put(content, { storeCodec: 'dag-cbor', hashAlg: 'sha2-512' });
   const path = `/ipfs/${cid}`;
   await ipfs.name.publish(path, {
               lifetime: lifetime,
               ttl: lifetime,
               key: keyName, // optional
           });
   return content

5. Resolve: Param (peerId: string) Returns (Content: Object)

   const path:any = await all(ipfs.name.resolve(peerId));
   console.log('path: ', path)
   if(!path) return false
   const cidStr = path[0].replace(/^\/ipfs\//, '');
   const cid = CID.parse(cidStr)
   const { value: content } = await ipfs.dag.get(cid);
   return content

6. Update: Call Resolve function and get Content with peerID Update previous content with new Content

   const cid = await ipfs.dag.put(new_content, { storeCodec: 'dag-cbor', hashAlg: 'sha2-512' });
   const path = `/ipfs/${cid}`;
   await ipfs.name.publish(path, {
               lifetime: lifetime,
               ttl: lifetime,
               key: keyName, // optional
           });
   return new_content

@ruffiano89 How to secure Update API? anybody on the internet can connect to my Blox and update my DID document. and because you use IPNS there is no validation by hash.

@ruffiano89 any suggestions for namespace fula.diddoc: import {create, update, resolve} from "fula.diddoc" ?

@ruffiano89 for testing can you please provide a sample Content: object? or instruction how i can generate it?

import fulaProvider from 'fula-provider' const didProvider = fulaProvider(ipfs) didProvider.create() didProvider.resolve() didProvider.update()

I will add source code into fula-sec with test case and you can use as reference. Pls, feel free to ask any question.

await ipfs.name.publish(path, {key: keyName,}) we will add here pem key which is temporarily key after publishing we will remove it. key is only belongs to specific user which is owner.

Each time when we publish new content or update user will use encrypted pem key. after all process should be removed, because its temp pem key. we dont need keep always

@ruffiano89 How the client (fula) generate pem key? Is it coming from blox ? How the blox know this is owner? How owner can access other to use this API?
