Hi again, Patrick!
I will try to give you answer for your questions in detail:
There is button "secure random" for generate random bytes.
This launch activate function secureRandom and I see there is separate file with name secure-random.js
I see in this script source code there using two entropy sources:
1. Browser random (window.crypto or window.msCrypto)
var crypto = window.crypto || window.msCrypto;
this is Web Cryptography API:
https://msdn.microsoft.com/en-us/library/dn265046(v=vs.85).aspx

2. And sometimes, if this is supporting - there is using nodeRandom function;
var crypto = require('crypto')

This modules is easy for include, but it can give pseudo-random values because this is the external modules.
So I did add XOR and additional value for XOR. You can find this value in the source code of the script brainwallet.js

1. Secret Exponent (button). This generate value from which depended hexadecimal value of private key.
2. Root Key (for Armory and Electrum deterministic chains of wallet generators).
3. XOR tab - just for fun.

1. Armory and Electrum is deterministic chains generators.
This can give chains of paper wallets [private_key and address].
Seed for this generators have encoded root key and chain code.
For example Armory... First two strings from seed is hex of root key (easy16 encoded). You can check it in converter tab.
Another two strings is encoded chain code hex.
Four strings seed - is backward compatible with the official brainwalletx,
and this can be checked here https://brainwalletx.github.io/#chains
But chaincode in official brainwalletx varies uniquely from root key and only root key is seed (two lines).
And for both values can be applied XOR.

2. If anyone generating secret exponent - he can get different values of private key in WIF (wallet import format).
This is a paperwallet for import and saving, holding and have full access to address.

3. If anyone want to remember only simply password (brainwallet)
and if it can be hacked by dictionary attack - then
this user can using his own random_seed parameter
and do XOR to get secret exponent and private_key and address
which is depended from this simple password, but with cryptographic strength.

In this case user need to download brainwallet in ZIP, unzip it,
change random_seed parameter in the file brainwallet.js
to set this his own, and use this brainwallet locally (on the USB flash for example - it is portable).

I don't see the link to this modified brainwalletX in the bottom of the page, because I don't do hosting it.
I didn't push there rghost link, because file will be deleted from this file-sharing service after some period...
There is only links to official brainwalletx repositaries...
So you can upload this zip on your hosting and change this links
by found it in the bottom of the source code in file index.html
Then users can using they own random_seed values and do XOR theirself anywhere.

How to run it? I see there is .jar file. It need java. Is there any portable java without install?
Can I compile it to .exe?
Also is there any another votecoin GUI for windows?
How to do "dumpprivkey votecoin_address" if votecoin-cli.exe did give me generated address and I see wallet.dat?
Can I parse wallet.dat data to get private_key?
Can I import another private key from zcash for example?

How to do solo mining bitcoin gold on the core-wallet through RPC-server?
I want try to find nonce from one block, but I cann't be sure that it will not be rejected.

Why I don't see total available supply and full btg balance here: https://btgblocks.com/ and here https://btgexp.com
Why I see only mined BTG after the launch btg mainnet?
I see full balance in my BTG qt but I don't see this balance in btg block explorers.

How to do solo mining to my qt-wallet without any solo-pools? Is there using getblocktemplate method???
Can I do it without any dev-fee?
I using BTGProxy https://github.com/sammy007/zcash-proxy
+ EBWF BTG miner + Power limit in MSI Afterburner,
because intensity change not working in this miner.
But in frontend of BTGProxy I see this:
Upstream
Name   | Url | Accepted | Rejected | Fails
Main | http://127.0.0.1:44444 | 0 | 0 | 5

ccminer tpruvot can connect to BTGproxy but cann't get work and process it (maybe need to specify nonce offset, I don't know what it is),
and when directly connect ccminer it to my wallet I see error method get_work is failed...
Also, as I understanding, like zcash proxy This proxy charges 2.0% devfee.

I cann't understand what fails is mean, maybe it's declined solutions for blocks.
In this case I lost 5 blocks.  

WOW, how to recompile this shi~?
P.S. hahhah it's about pool.

You can calculate it here yourself: https://www.crypto-coinz.net/crypto-calculator/

I have this wallet in zip, but there is no working all functions. Maybe their server was been hacked.
Here is only btgwallet.online listed http://btcgpu.org/downloads/ -> https://btgwallet.online/
And I have it in zip-archieve and it working locally.
If I enter BTC private key in the form Verify -> I can see my BTG address, but DO IT LOCALLY without any connections!
See source code for find try to do connections! Disconnect internet! Unzip zip, and open index.html without Internet!
For transfers use syncronized core qt with imported BTC_privkey (move your BTC to another address earlier).
For using Core QT client - first do importprivkey, then syncronization (or -reindex and -rescan).
Do not send your keys, passwords and logins to any links, emails and forms on any sites.

I got email with this sh~t:
DON'T ENTER ANY KEYS HERE, MAYBE THIS IS FISHING TO GOT YOUR DATA.
TRANSFER YOUR BTC BEFORE ENTER PRIVATE KEYS AND DO IT LOCALLY IN CORE QT CLIENT.
Check all qt on virustotal.com

Hello. Is there any site, like https://bitnodes.earn.com/ to get copyable addnode list
with nearest active peers Like http://zpool.ca/explorer/peers?id=2377
for just copy and paste it to config and get fast syncronization without any bootstrap.dat

http://btgblocks.com/movement
Also, I received 0.006 BTG mining rewards from btg.suprnova.cc to my btg_from_BTC_address
and see this transaction in this block explorer with my BTC_BTG.
My qt still not syncronized and in -reindex mode so I cann't transfer this. But... I'll hold it and do mining.

I did do -reindex and saw my transactions then. It has status "conflicted" and after restart qt I cann't see this transactions.
I did export all transactions to *.csv file and open it as text. Then I see addresses and can do "dumpprivkey GUN_address".
But I don't see any transactions and my blocks in block explorer.
This is because I did run qt with parameter -reindex, in this case my qt again download blockchain from another nodes.
But only my wallet was been a node with my blocks.
I did have only this nodes in my config.conf:
addnode=seed.guncoin.info
addnode=seed2.guncoin.info
addnode=seed3.guncoin.info
and as I see all this nodes is on one domain. It was been disconnected ALL if guncoin.info server disconnected
and my wallet did mining my own blockchain. I saw 30000 GUN in my wallet with confirmed status.
But all this blocks was been declined.
Now I added all nodes from this list: https://chainz.cryptoid.info/gun/#!network and now solo mining is good.

Also, I don't see paperwallet and if you want to do brain wallet, you can add your prefix bytes to this brainwalletX:
https://bitcointalk.org/index.php?topic=2359426.msg24488519#msg24488519 (open source, local, zip)
Private key version, public key version, compressed or uncompressed keys and addresses.
(index.html <ul class="dropdown-menu dropdown-menu-two-column">)
Then you can host it on your site if you want. See source code.

Also, can I specify my address to get rewards?
I see this is possible here, in this proxy: https://github.com/sammy007/zcash-proxy
parameter "coinbase": but this is for zcash and btg.
So do you have any proxy like this or another resolution?

Wow, it's cool, because I did solo mining to zcash-proxy with get block template. No one blocks found.

Devs, can you add option or parameter for skip blocks like this: https://en.bitcoin.it/wiki/Bitcoin_Core_0.11_(ch_5):_Initial_Block_Download
and then recompile windows-qt.exe
If I know block number or block hash, where is my bitcoin go to my wallet,
I no need to download and syncronize all blocks from bitcoin blockchain
which was been generated earlier then this.

I did add my private key to syncronized BTG wallet, and then automatically was been started -reindex
now I need to download 8 years bitcoin blocks again. =(

Also, when web-wallet will be working???

No, getwork is a good method. I'll using EWBF miner + power limit in Afterburner.

Just leave it here:
2017/11/15 18:46:24 Malformed stratum request from 127.0.0.1: invalid character 'P' looking for beginning of value
Need to fix it.

P.S. It's my bug, i did try to connect -o 127.0.0.1:PORT but need to use string -o stratum+tcp://127.0.0.1:PORT
Now ccminer is working and get_work method is working through getblocktemplate proxy.

Best regards.

Is there any win-x64 cuda miners with equihash, where getblocktemplate is supporting?
Can I install any getblocktemplate->get_work proxy or my own stratum server to use this bullsh~t?

How to run solo mining with getblocktemplate method for equihash algorithm in ccminer tpruvot (Windows x64)?
I see only parameter for disable getblocktemplate method.
method get_work failed


Also, is there any cuda-miners with getblocktemplate for equihash and nvidia cards?

I using ccminer from tpruvot, because this is one miner where I can set intensity - to get stable mining with stable hashrate.
Here https://en.bitcoin.it/wiki/Getblocktemplate
I can see supporting miners:
Mining software with GBT support:
BFGMiner 2.8+
cgminer 2.9+
Ufasoft Bitcoin Miner 0.39+
Butterfly Labs's EasyMiner
But I have NVidia cards. I know about ccminer tpruvot supporting getblocktemplate, but for equihash it not working.
Is there any miner for nvidia with getblocktemplate and intensity change available?
Is there any converting proxy??? Can devs do getwork or their own solo miner with stratum server, like sgminer??

[ANN] Bitcoin Gold : Make Bitcoin Decentralized Again
Bitcoin Gold qt.exe for windows: method get_work failed.
I cann't try to do solo-mining. About what decentralized do you say?!
If mining pools will be shut down - no one solo-miner cann't supporting BTG and confirm transactions.
It's not decentralized.

P.S. Also, where I can buy BTG and withdraw it to my BTG address?
I don't want to buy any illiquide futures.

Special port for ccminer tpruvot - added there.

No airdrops. ?!! xD

I got my BTG address without import private key (but priv need to do transfers).

---

1. https://brainwalletx.github.io/#converter -> select GameCredits (0x26 byte) ->
FROM Base58Check: BTC address -> TO Base58Check -> BTG address.

---

2. https://btgblocks.com/ -> G-address to the search field -> and see my BTG there (transferred before 491407 block).

---

Now I can do mining there but I cann't transfer. I don't want to download any blockchains and I'll using web wallets.
If get_work method will be unlocked in windows-qt, I'll download it, syncronize and want to do solo mining then.
