How do i do this? can i just intstall the apk and run it? Or do i have to do something more

[Android Software/Hacking General [Developers Only]] OPGT:
FIX FOR THE BUG!!!!!!!!!! LOOK HERE!!!!!!

I found that when you open it and and enable the seeder, exit the app with the home button! Not the back button. Makes options stick. (Even when you reboot) Tested this and working for me here on galaxy note i717. :)
[Android Software/Hacking General [Developers Only]] kevdliu:
That's because when you press the home key Android "pauses" the app in memory. If you leave it closed for long enough Android will kill it and then the button will revert.

[Android Software/Hacking General [Developers Only]] e2zippo:
Seems to work great on my I/O ****ed up TF300T, thanks A LOT!
[Android Software/Hacking General [Developers Only]] espionage724:
Probably because the app isn't being closed, but is instead running in the background. I believe it resetting to "Off" is a bug, but the function is still enabled (can verify via some command).

Type this into a terminal emulator or ADB:

watch -n 1 cat /proc/sys/kernel/random/entropy_avail

If your value is around/above 3000 and is refreshing every second or so, you're good to go. If it's not working, you'll likely see much lower values

Hi using nexus 7 with smoothRom. Installed seeder apk

typed in your command and output is sh: cat: /proc/sys/kernel/random/entropy_avail: No such file or directory

What is wrong?

EDIT: Speedy settings is on and start auto on boot

Can someone compile a list on different methods to check whether seeder is working for noobs like us

Is checking methods different for people who flashed the zip and people who installed the apk?

What are the advantages of flashing this rather than installing the apk?

Yes, that's 4.2. Someone on Google Code mentioned that wpa_supplicant would be the only user of /dev/random. So I switched wifi off and tried again, and I'm still seeing drops. (Interestingly enough, there are noticeable drops when turning wifi on again).

Does that also work when i just mounted urandom to random or only for the app? I tried it and had between 100 and 200 (nexus 4). Where could the problem lie? I created the init.d script just like he sad.

[Android Software/Hacking General [Developers Only]] Mr. Steve:
The apk needs to either be opened each time you reboot, or set to automatically turn on during boot. Flashing the zip would be a more permanent one time affair.

Has anyone else tried:

?

I did it on my S3, but it's so fast (KT7 2.1Ghz) that I can't see much a difference. Maps seemed to behave better though, and my upload on speedtest (Wi-Fi) doubled. Very possible placebo effect, can anyone else test.

That would end this argument pronto.
[Android Software/Hacking General [Developers Only]] AlanVG:
I just wanted to say THANK YOU!

My One X has never been this fast, and the APK made the install incredibly simple!

[Android Software/Hacking General [Developers Only]] debork:
I rebooted after taking off zeppelinrox's RWUT/WWUT values, and now I see more up/down activity on the watcher.

Thing is, how much entropy_avail doesn't seem to decrease consistently based on activity. As I mentioned, when I had my values up in the 2000-3000 range, there was 0 decrease except for the regular flushing @ 3000bits. Now when I open the same apps, do the same things things, I get a chunk of my avail pool removed sometimes, but but never below the min threshold of 128.

Which is kinda...weird. I think I'm going to experiment moving the theshhold values up until I get consistently no change no matter the activity.
[Android Software/Hacking General [Developers Only]] TKG26:
hmm guess its not doing anything then LOL :)

[Android Software/Hacking General [Developers Only]] osaeed:
lol, believe it or not man, I may have lost root on my phone for some very odd reason. If i launch terminal and type su, it just hangs. I went into superuser app, and did a update and it says checking root access and doesn't say anything just pauses.

Also I am on Gingerbread 2.3.4 Stock tmobile rooted rom.

Its ok, ill wipe everything and install a fresh stock rooted image. Thank you for your help.

EDIT: Nevermind lambgx02, my microsd card was the culprit. I thought about checking my sd card and running a flash test just to check maybe the memory card could be the problem and what you know, the flash memory is getting weak. This has nothing do with your app, its just I had the memory card for a long time and I have used it in other machines. Since my apps save to the external memory, it was having issues writing and reading to the flash memory. Time to get a new one.

I will then test the new memory card tonight. I am so sorry.

Hey, no worries! I'd rather people report anything suspicious than have no feedback and miss something critical. Last thing I'd want to do is release a piece of software that harms peoples' devices.
[Android Software/Hacking General [Developers Only]] thegreatergood:
I'm using an init.d script to start the binary ... is there any way of verifying if its running ? ....
[Android Software/Hacking General [Developers Only]] lambgx02:
Sure.. just:

ps | grep rngd

To make sure it's doing its thing, try:

watch -n 1 cat /proc/sys/kernel/random/entropy_avail

(via adb/ssh)

.. then start firing up and using apps. The entropy available should rarely drop below 2000 or so.
[Android Software/Hacking General [Developers Only]] lambgx02:
Oh, by the way - are you using the rngd binary from my first post, or the one extracted from the apk?

The original one in my first post only runs once every 5 seconds, which isn't frequent enough. I just updated it now.
[Android Software/Hacking General [Developers Only]] thegreatergood:
i figured... wanted to ask if you updated it ... thanks ... was using the zipped version
[Android Software/Hacking General [Developers Only]] thegreatergood:

[Android Software/Hacking General [Developers Only]] RogerG:
hey lambgx02, just wanted to say THANKS A LOT - not only for what seems to be a really astonishing achievement in making android more lag-free (can't test myself atm), but maybe even more for being all-around excellent: helping people, responding to feedback, allowing integration in roms & mirroring, etc.

just a quick question from a conceptual pov (I obviously have little to no actual knowledge of rnd, crypto & android): would it be feasible, to create one rather big random-data file e.g. once a week, instead of having to create new randomness all the time? (or does it have to very recent, e.g. to minimize the possibility of it being tempered with?)

Hey dude!

First of all, thanks!

I've used your binary and got the values from this command: watch -n 1 cat /proc/sys/kernel/random/entropy_avail

(between) >≃ 2000 and <≃3500

So, I've changed the sources and get an original from CyanogenMod (jellybean):

Another values using qrngd:

I installed liteROM with this mod (or call it whatever u want), but it doesnt really seemed any different. I mean chrome is still lagging when switching between tabs. So are bikerace and boost2 games. (not a constant lagging,but in an average of 30 seconds,they lag for a half a second,or something like that)..

I also tried dman's CM, and the older GB roms, and non of these lags existed (I dont know about chrome,cause it doesnt run in GB(in CM it was flawless),but the games are perfectly smooth both in GB and CM ten). So this must be something in stock ICS roms (and roms that are based on them), but I havent experienced that this mod would help.. in which cases should I see the difference? :/

I dont mean to be rude, and I really appreciate your work, Im just confused and curious

reboot? on my G-tab10.1, I had to manually push the files and then change permissions on them. once I did I got that error untill I rebooted. then it worked.

to those that wonder if you can uninstall it, from what I have seen, YES> you will simply need to remove the files that the CWm zip loads into your system folder. unzip it on your PC and use that file structure in teh system folder as a guide to find them.

[Android Software/Hacking General [Developers Only]] nhshah7:
for those that are not getting any results or it keeps setting to "off" when returning to the app, try the non-CWM method in this post. helped me get the values to show up and for them to be over 3000+ :) not sure if it's giving me a performance boost just yet but want to keep testing. Thanks OP!!
[Android Software/Hacking General [Developers Only]] debork:
I've had it in an init.d, so yeah it applies at boot (double-checked values from /sys/proc/kernel/random/)

I'm now running at Read-256, Write-512. My entropy values only go up, until its past 768 and only then will it ever drop down to 520ish if I run something: http://pastebin.com/bcSj3BWs.

The above paste is pretty much consistent no matter what type of activity I do, only difference is that more touches tend to increase the rate of entropy_avail up (fed, like I said, by hardware sensor).
[Android Software/Hacking General [Developers Only]] droidleaf:
entropy_watch is useless. To actually find out if this is necessary, someone needs to add a printk or counter in the kernel for blocking reads to /dev/random. Then create an identical app that wakes up every second, reads /dev/urandom, but doesn't seed /dev/random.

I strongly suspect people are seeing less lag because the 1 second activity is keeping the cpu clocks up.
[Android Software/Hacking General [Developers Only]] lordxcom:
so which works best?

the APK or the rngd.zip?

installed the APK, can't tell a difference.

If i need to push the rngb in, how do i?

[Android Software/Hacking General [Developers Only]] Krunk83:
Not sure this does a damn this, this app.
[Android Software/Hacking General [Developers Only]] zeppelinrox:
You can put it in any init.d script.

But the point of it is that you wouldn't need to run any other seeder/rngd tool to keep entropy_avail full

edit: Just this command: busybox sysctl -w kernel.random.read_wakeup_threshold=1376

The second line is just to see the entropy_avail contents get updated

Yeah that's the exact expected behaviour.

Max = read_wakeup_threshold * 3

Min. = read_wakeup_threshold * 3 - read_wakeup_threshold

[Android Software/Hacking General [Developers Only]] AglarondTX:
I've done enough tests that I have some real numbers. This was done on my Galaxy Stellar, since the results (to my eyes) were more noticeable than on my Nexus 7.

I tested from a fresh reboot. Start [app], time. Force stop [app]. Repeat 4 more times. Take average.

Chrome (to bookmarks page):

Without patch: 2.1 sec

With patch: 1.4 sec

Maps (to showing my location with full map draw):

Without patch: 4.2 sec

With patch 3.1: sec

Google+ (to main page with full picture rendering):

Without patch: 3.5 sec

With patch: 2.2 sec

Bible (YouVersion) (to current passage):

Without patch: 6.3 sec

With patch: 6.5 sec

I didn't see anything near 4 or 5 times faster, but the speed increases were definitely noticeable on some of the apps. Oddly, the Bible app was actually .2 seconds slower on average. Probably no difference at all.

I also did a few framerate tests, and all came within a few fps of each other with no benefit one way or the other. It doesn't appear to help framerates at all.

So, not totally a placebo effect, but some of the benefits people are claiming I wasn't able to back up on my hardware. That said, there could be differences in hardware that aren't accounted for here. More people just need to test and give real numbers.

Edit: I haven't noticed anything significant as far as battery life goes. I just switched from m-kernel a25 to a26, so it would be hard for me to separate the difference and I don't feel like taking the time to get real numbers on this. Just the fact that I haven't noticed a problem makes me happy enough.

Also, I didn't use the APK; I flashed the zip that was linked earlier which contains an init script to start it up. Don't know if that makes a difference, or not.
