                Example code for extracting JS-IPFS node keys for external encryption/decryption.
              
          
        
      
        
  
      
    I spent a very long time trying to figure out how to encrypt something with an IPFS peer's ID so that only they can decrypt it
(in JavaScript).
This gist is to save anyone else from that same time-sink.
Encryption

Say you have an IPFS node as your peer, and their public key is this protobuf-encoded gibberish spit out by IPFS:
// for example from the command: node.id()
let publicKey = 'CAASpgIwggEiMA0GCSqGSIb3DQEBAQUAA4IBDwAwggEKAoIBAQDC7gCqYWtRFmfQ8XZHnFnqB2sdPjprZgDOvz3Hl6NLGPpz95JVqguxQ9XDLnmPPFVOXEdMWohXOmWkQ4AF/6MDLz68q9/+xlvGRrwXE6gbhF15rBV+2A6LtCsbTNnzd7G+YmHMgBNk8UF4zB6Cg/6o2770fqp8khrTG1rwRXX2Cl0z/hEcIMFCAHEQpnmigP1gibtJi6cEjfjHQkqRF8ndCSNyUucgBkWPuJKEFWwAh5AJBVeEbWZngFGQ4jhp14RQ57cHv7COOQk8X3rSkJKMnyURm1iHK635TaJXpjaW8gD13imKUZHFCxS1JLIa3QTh8bk33+kK1jzkPN/XAC2BAgMBAAE='
