Long time no see you.

Today I'm glad to release Google TwoFactor Authenticator on PSP.
Currently it officially supports iOS/Android/Blackberry, but here is another choice :p
You can setup 2-step auth for google account.

You can use not only mobile phone call/email but also Google Authenticator applications.

In that picture, you see that [2c] is where secret key is input. In my application, you store secret keys to keys.txt.

# This libpuer pack contains my homebrews.

How to use:
1. copy PSP/GAME/google2fa to ms0:/PSP/GAME/google2fa (you can change directory name)
2. write secret keys to ms0:/PSP/GAME/google2fa/keys.txt
Here secret keys mean what you are supposed to input to your mobile phone.
Please write only keys.
3. adjust PSP's time using NTP (auto mode).
4. execute "Google TwoFactor Authenticator" and you will see 6 digits token!

Warning:
This stores keys in raw form. Although it shouldn't be bad threat as you don't write profile name, please never lose your PSP ^^

NDS, iPodClassic, bla bla... cannot be supported as they don't have NTP feature. hehe.

You can crypt it easily, I don't know what language do you use but if it's C++, this should be ok: http://www.codeguru.com/cpp/misc/misc/c ... .php/c3899

And we don't care about our stored password, but what prove us that you don't steal password by this way ?
I don't say you do but it would be fine togive the source: we can't trust everybody.
EDIT: never mind: you already give it ! :)

Well, this is just a sample implementation in C...

Actually the problem is that you need to write to keys.txt directly --;
There is very easy encryption for text: to perform "abcdefghi -> afbgchdie" transformation twice (btw if you know about 里々 stuff, this is what satori.dll does)

>toBsucht
puerforge is just a test of kernel mode. I used it to debug sctrlHENFindFunction(). Well, currently it can reboot PSP...
