Naming convention: key vs privateKey

[BarakBinyamin]

I'm having some difficulty shifting from connect to AuthHandler when using the client module

I used the type definitions from @types/ssh2 to help me through, idk how that's automatically downloaded when I install ssh2 but thats cool...

A ConnectConfig has privateKey field.
A PublicKeyAuthMethod has key field.

Are they both private keys or is one supposed to be a public key?

Here's my code for reference:

const Client   = require("ssh2").Client       
const sshClient = new Client()
sshClient.connect({
  host        :  myServer,
  port        :  22,
  username    : "milo",
  authHandler : function(methodsLeft, partialSuccess, doNextAuth){
    let  authConfig={
        type      : "publickey",
        host      : myServer,
        username  : "milo",     
        key       : key
      }
    doNextAuth(authConfig)
  }
})

vs

const Client   = require("ssh2").Client       
const sshClient = new Client()
 sshClient.connect({
    type           : "publickey",
    host           : myServer,
    username       : "milo",     
    privateKey     : key        // privateKey ~/.ssh/id_rsa in plaintext
})

Thanks!

The documentation in the README states about the key property:

Can be a string, Buffer, or parsed key containing a private key
