why would someone use a public node to start forging?
this tipservice is really cool, so I want to make sure it is secure

almost all tx are ok to send publicly (as long as they are signed locally), but start forging is one of the exceptions

It was my fault, as I wrote above :( I do not run forging, I made the transaction and did not sign them locally, as it was necessary. Now I have corrected the situation, now uses only the local node!

PS. I'll planed to use this code:
Code: [Select]
$pwd2 = '';
for ( $i=0; $i<rand(4)+4; $i++ ) { $pwd2 .= substr(str_replace('+', '.', base64_encode(pack('N4', mt_rand(), mt_rand(), mt_rand(),mt_rand()))), 0, 22); }
$hash2 = hash('sha512', $pwd2);
Code: [Select]

tips@tips:~$ for i in `seq 1 5`; do php -f 1.php; done

yes, I saw the post. you can use remote node with local signing, just block the forging tx!
I cant read the code that is not C, but hashing the output of the rand() seems much safer. as long as the rand() is not always making the same sequence (eg. always srand with same seed), it should be good enough for input into hash.

what is the actual algo for this hash512  function?

SHA-2 512 bit hash function.
since it is for tip accts, should be fine, but if you are feeling ambitious: http://security.stackexchange.com/questions/4687/are-salted-sha-256-512-hashes-still-safe-if-the-hashes-and-their-salts-are-expos

maybe another random number that determines the number of iterations? not knowing how many iterations of hashing, even if the original password was cracked, the output after each hash would need to be tested. wont stop a determined attacker, but with the relatively small amounts any deterrent should be effective.

I was also thinking this random number could be used as a PIN that is displayed on the screen and if the user chooses to, not stored anywhere. Just an idea to experiment with making the user experience more like real world things where they say here is a 4 digit PIN, dont lose it!

Micro-payment service NxtTips came back!


Vastly improved security as well fixed bug, which resulted in the hacked of 4 passphrases :)  Old users only need to create a new Nxt-account, all other settings unchanged. I hope that in the near future it will again be included on NxtForum & SupernetForum.


Thanks to everyone who took part in this!

Good news!

I've just logged in and created a new Nxt account with 0 NXT. How can I transfer my NXT from the old tips account to the new one?

My plans include completion plugin for Mozilla & Chrome that there was an opportunity to send micro-payments by clicking on Nxt-address on any website.

So, twitter tipping might be a good alternative.

Hi all!

Some news service NxtTips:

Updated script for Greasemonkey and Tampermonkey, now do not need to write a signature nxttip: (on BTT forum) what would the script found your address. Refused to use the image as it is not all like it did just a reference. Just completely rewrote the code in pure javascript, that would not use heavy type library jQuery.




Just set the start-up script for the site nxter.org - there is also looking for links to news and replaces them with the ability to reference type. If you have the addresses of sites where you have to run my script - write, I might add. GetStarted update the site will be in the near future.




Small RoadMap (ToDo):
  • Finalization of NxtForum (SMF engine) plugin  that would just get away from jQuery
  • Replacing the video in the GetStarted as well as updated information
  • Creating a Twitter bot to implement features such as via twitter (idea xcn)
  • Integration with SuperNET (idea jl777)
  • Ability to create triggers for any accounts Nxt. Let me explain with an example: For example, you wrote a book and want to sell it using Nxt, it will need a profile on NxtTips specify the address (NXT-...) which will come to pay for the book, the minimum value (ie, any transaction with the amount more said falls under the right trigger) and action - such as sending the AM to the sender of the transaction. Thus, if the monitored address receives an amount equal to or greater than the cost of the book, he sent her a link to download as AM.
  • Maybe someday reach the hands to reddit
The order of development position is not fixed
