Cannot parse privateKey: Unsupported key format

dogui1718 commented 5 years ago

I am getting this error when I try to connect with server using a ssh key.

(node:13393) UnhandledPromiseRejectionWarning: Error: Cannot parse privateKey: Unsupported key format
   at Client.connect (/node_modules/ssh2/lib/client.js:146:13)

   at <anonymous>
   at process._tickDomainCallback (internal/process/next_tick.js:228:7)

I am using this key format

-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----

This is my code

client.scp({
    host: '*******************',
    username: '******************',
    privateKey:  '~/.ssh/user',
    path: `***************************`
  }, `*******************************`,
  function(err){
    if (err){
      console.log(err);
    }
  });

Looking for more info about this error, I guess you must to add a new property for ask which ssh key formar are using. Take a look at this documentation:

This is not a bug. You should use:

client.scp({ host: '*', username: '**', privateKey: fs.readFileSync('~/.ssh/user'), path: `***** },***`, function(err){ if (err){ console.log(err); } });

Thank you @geovanneb, your solution worked for mу. However, instead of ~/.ssh/id_rsa I had to write path like /Users/sergey/.ssh/id_rsa. For some reason fs did not recognize ~ correctly

I tried using exact path @geovanneb, here is my code

test.scp("***************************", { host: "localhost", username: "********", port: "2223", privateKey: fs.readFileSync('/home/***********/xyz.key'), path: ".", }, (err) => { console.log(err); });

@SergeyMell, the problem you encountered is not specific to this library, but rather node.js. You can test with this simple code:

const fs = require('fs')
console.log(fs.readFileSync('~/test-file.txt').toString()) // this would throw error

You can use the solution in this SO entry to work around that problem.

    scpclient.scp({
        host,
        port,
        username,
        privateKey: require('fs').readFileSync(SSH_KEY_PATH),
        passphrase,
        path,
    }, dest);

same error, console.log(require('fs').readFileSync(SSH_KEY_PATH)) gives a Buffer
