    Here is PRXdecrypter 2.4b - a minor update, with all the keys up to 6.20 courtesy of bbtgp, who spent many hours reversing to get them, whereas I just spent 10 minutes updating my source code.

    Thanks to the usual suspects + ErikPshat for some of the latest keys.

    UPDATE: 2.4b released (29th March)
    2.4a --> 2.4b
    - Decryption error for an old key, tag 0x4C940AF0, fixed.
    - Decryption key added for pops_04g.prx from 6.XX firmwares - tag 0x457B1EF0
    - Slightly more information when encryption is likely to fail (SHA-1 check warning)
    - NOTE: key for tag 0x2E5E10F0 does not appear to be working due to a new encryption method. I'll look into it.
    - New EBOOT.BIN key added for tag 0x2E5E12F0. As above, might not work.

    2.4 --> 2.4a
    - New EBOOT.BIN key added - fixes "tag error 0x2E5E10F0"
    - Can extract the nand_updater/lfatfs_updater from old updaters again

    2.3a --> 2.4
    - All firmware keys up to 6.20

    It's been 4 years since I first entered the PSP scene, and those 4 years were a privilege to be part of. A lot has changed since the days of kxploit. We've had a lot of fun battling Sony back and forth with their constant diversion and obfuscation tactics, watched a lot of drama unfold over some quite petty incidents, and seen some real triumphs of talent and ability from great minds such as Dark_AleX, but the past few months have seen a steady and obvious decline in the number of people following the scene and the number of developers still active. With this in mind, I thought it'd be worth letting those of you who are still around that I have sold my last remaining PSP, my silver first gen PSP 2000 - it served me well.

    I am still interested in the scene and will continue to update PRXdecrypter and PSPident as long as there is still a demand for them (please reply to this thread if you still want to see these apps updated). However, if/when the time comes where they require a major rewrite, which would obviously be impossible for me to do without a PSP, I will clean up and release the source code.

    For anyone wondering why I did this: partly because I don't see an imminent recovery in the PSP scene soon, partly because the hardware is outdated (and has been for a while), partly because it has been sitting in my drawer for months doing nothing, and a tiny bit because I wanted to free up some cash to buy a Nexus One (a quite amazing phone, if anyone is looking at buying one).

    Many thanks.

    Thank you for your excellent tool. It helped me to extract table keys in Sony update in 10 minutes before I even knew what that EBOOT is about. Really looking forward to your release of source code. Nexus One is on my wish list too.

    Cheers

    Thanks for the update jas0nuk !! :D

    Sad to hear you have sold your PSP. You have been a great force and inspiration for the scene for a long time. All you have done is much appreciated. And thanks for lending support to folks like myself who are going to stick with what is left of the scene, to the bitter end.

    Glad to hear you are going to keep updating your programs for us. That is very kind of you :)
    Maybe we can all get together and have all this fun, all over again when PSP2 comes out ? :p

    Thanks again bro.

    Thanks for everything Jason, I agree, the PSP scene is 90% dead .. But those who want homebrew have everything they want thanks to the "test m33" option in DC8, so it's sort of okay that Sony's winning ;)
    Btw I recon 90% of people here did NOT play a lot of games on their psp, but enjoyed the modding process itself more than the games (myself included really).. Every time waiting for the next m33 to come out, then install it, then... putting the psp away again lol :p It's been a good run!

    Honestly, I'm going to cry ;_;

    Thanks again, mate. I've been around a little less than a lot of the people here (3.40) but I enjoyed the PSP's many ups and downs. Unfortunately, the scene is slowly dying unless someone makes some sort of breakthrough. Hey, maybe it'll happen. Maybe not.

    I'll still be around though, forever tinkering with custom themes and PSone eboots.

    So true. 90% of the fun was modding the PSP.
    The other 10% of the fun was actually playing games on it. :)

    I myself, can't resurrect the scene, but I do have a few more cool animated themes, and fun homebrews up my sleeve for PSP ;)

    Thankfully jas0nuk is going to keep interst going for a bit with PRXdecrypter. :D
    Great news indeed, ecpecially since many cfw users are now 3000 owners, who do not have the luxery of Pandora's Test m33 option...

    Thanks again jas0nuk !! :D

    can i decrypt game demos with this tool? PRXDecrypter showed this error message "unsigchecked failed" when i tried to decrypt game demo's EBOOT.PBP. I've also tried to decrypt DATA.PSP which extracted from EBOOT.PBP. But it failed and printed an error message "unknown header 'NPUM'". Anyone knows? thanks in advance

    PS: Thanks jas0nuk for updating this excellent tool. ;)
