Google chrome on android not opening encrypted tw5

[passingby]

I tried to open an encrypted tw5 hosted on tiddlyspot in google chrome on android on my samsung galaxy edge. It does not open. At first i thought my password was incorrect but then i found that same file opens on other browsers on the phone such as firefox and internet (samsung stock browser). The same file opens without difficulty on laptop on chrome. Its just on the phone that it does not open.

There must have been some change to the internal JS encryption library -- decryption doesn't work on AndTidWiki now either.

Error messages might help debug the problem. Unfortunately, it might be necessary to use a desktop app to connect to the console. There are instructions here:

Hi Mark

Chrome for Android doesn't let you just use a developer's console on screen. You have to link to your desktop, following directions that are apparently incorrect.

Anyways, after attempting to log in to the encrypted marxsal.tiddlyspot.com I got these 2 messages in the (remote) console window:

(index):932 Crypto error:URIError: URI malformed
(index):869 [Violation] 'submit' handler took 12335ms

I assume the index values are line values in the html, but don't know.

Do these messages provide any clue?

Thanks,
Mark

Do either of them have a stacktrace included?

I haven't used these tools this way, but poking around, the full long message is ...

1. URIError: URI malformed↵    at decodeURIComponent (<anonymous>)↵    at Object.fromBits (http://marxsal.tiddlyspot.com/:145:171)↵    at Object.ia (http://marxsal.tiddlyspot.com/:190:236)↵    at Object.decrypt (http://marxsal.tiddlyspot.com/:190:300)↵    at callSjcl (http://marxsal.tiddlyspot.com/:929:31)↵    at $tw.utils.Crypto.decrypt (http://marxsal.tiddlyspot.com/:957:10)↵    at Object.callback (http://marxsal.tiddlyspot.com/:1671:36)↵    at HTMLFormElement.<anonymous> (http://marxsal.tiddlyspot.com/:882:15)"
2. __proto__:Error

I can see that the error is inside the first catch inside of $tw.utils.Crypto = function() function  (my line numbers may be different since I'm using 14-pre-release.)

The stack trace:

callSjcl ((index):932)
decrypt ((index):957)
callback ((index):1671)
(anonymous) ((index):882)

I can see that the form has captured the correct password, so it's not a simple form error.

If there's some particulare error message or variable I should be looking for, let me know.
