Invalid key length error

[bjkeyser]

Hello... mostly worked but run into this error when I try to stream from my phone over aiplay. Running iOS 10 beta and OSX El Capitain 10.11.6. Any thoughts?

Have you attempted to stream with an apple product running IOS 9? If so, have you reproduced your issue?

+1, on iOS 9. Tested using node 4.5 and 6.4, on Arch Linux. The exception is triggered as soon as I hit play on my iDevice.

Search complete. Set up 4 device tunnels.
crypto.js:238
  this._handle.initiv(cipher, toBuf(key), toBuf(iv));

Same issue here on macOS Sierra beta: crypto.js:238 this._handle.initiv(cipher, toBuf(key), toBuf(iv)); ^

#302 + Nodetunes fix

[ghost]

Yes! that solves the issue

[jonathanmmoore]

I'm a bit new to this and have no idea how to apply this fix...can anyone help?

[yecine06]

when ths fix will be available on airsonos ?

[rightisleft]

I think the issue is that the pull request above has not yet been merged into nodetunes...

[discopolis]

I am seeing a similar issue:

Error: Invalid key length at Error (native) at new Decipheriv (crypto.js:239:16) at Object.Decipheriv (crypto.js:236:12) at Object.decryptAudioData (/usr/local/lib/node_modules/airsonos/node_modules/nodetunes/lib/helper.js:141:25) at RtpServer.

[discopolis]

And I have updated the helper.js folder to reflect the #302 fix but still not working

[paddyriyer]

The fix works for me. Edit the file, ~/{user}/.nvm/versions/node/v6.2.1/lib/node_modules/airsonos/node_modules/nodetunes/lib/helper.js

[isidore]

Worked for me: Editing

/usr/local/lib/node_modules/airsonos/node_modules/nodetunes/lib/helper.js 

replacing

var decipher = crypto.createDecipheriv('aes-128-cbc', audioAesKey, audioAesIv);

with

var audioAesKeyBuffer = new Buffer(audioAesKey, 'binary');
var decipher = crypto.createDecipheriv('aes-128-cbc', audioAesKeyBuffer, audioAesIv);

[naazy]

Thanks @isidore this worked for me!

[JoeCotellese]

Worked for me too!

[psieyes]

I'm not a proficient programmer at all but could probably figure it out with a little help. Would appreciate if someone could advise how I can edit /usr/local/lib/node_modules/airsonos/node_modules/nodetunes/lib/helper.js

and replace

var decipher = crypto.createDecipheriv('aes-128-cbc', audioAesKey, audioAesIv);

with

var audioAesKeyBuffer = new Buffer(audioAesKey, 'binary'); var decipher = crypto.createDecipheriv('aes-128-cbc', audioAesKeyBuffer, audioAesIv);

Thank you very much

[dabvid]

+1 Worked for me as well.

[ksho]

@psieyes Open terminal.

Type vim /usr/local/lib/node_modules/airsonos/node_modules/nodetunes/lib/helper.js to open the file.

Type /decipher to search for the string "decipher" and hit enter when it finds the line.

Type dd to delete that line.

Copy the two new lines:

var audioAesKeyBuffer = new Buffer(audioAesKey, 'binary');
var decipher = crypto.createDecipheriv('aes-128-cbc', audioAesKeyBuffer, audioAesIv);

Back in the terminal, type i to enter insert mode.

cmd + v to paste the new lines.

Hit ESC to exist insert mode.

Type :wq to save the file and quit.

[SimonSels]

Works like a charm. Thanks guys

[sspross]

perfect, thx a lot!

[igrek8]

Only worked with extra decipher.setAutoPadding(false) idk why

var audioAesKeyBuffer = new Buffer(audioAesKey, 'binary');
var decipher = crypto.createDecipheriv('aes-128-cbc', audioAesKeyBuffer, audioAesIv);
decipher.setAutoPadding(false);

[loretoparisi]

Had the same issue, and it worked with

  var audioAesKeyBuffer = new Buffer(audioAesKey, 'binary');
  var decipher = crypto.createDecipheriv('aes-128-cbc', audioAesKeyBuffer, audioAesIv);
  decipher.setAutoPadding(false);

[meglio]

Me too, experiencing this issue.

Same as @meglio on macOS Sierra 10.12.6
