=== Meta Checksums ===
There are 3 checksums at the offset specified by meta_offset. 

*The first is the sha1 checksum of the entire self file. 
*The 2nd checksum is the inverse of the first checksum. 
*The 3rd checksum is the first checksum XORed with 0xAAAAAA..AAAAAB 

The PSJailbreak payload ignores the actual checksums, but checks that the 3rd checksum is the 2nd checksum XORed with 0xAAAAAA..AAAAAB

[21:00:58]	<Mathieulh>	selfs are a mess to generate properly because a lot of values need to be calculated from the original elf file
[21:01:11]	<Mathieulh>	the problem is right now all the public tools use hardcoded values
[21:01:19]	<Mathieulh>	that are grabbed from various self files
[21:01:21]	<Mathieulh>	but are not calculated
[21:01:34]	<Mathieulh>	well that's one of the many problems actually
[21:01:35]	<jevin> 	Mathieulh, things other than elf offsets?
[21:01:40]	<Mathieulh>	yah
[21:02:03]	<Mathieulh>	sony also did some fancy things with the compression self format
[21:02:12]	<Mathieulh>	where values are off by a certain offset etc etc
[21:02:38]	<Mathieulh>	if you want to make a proper self tool
[21:02:44]	<Mathieulh>	you first need to reverse make_fself
[21:03:06]	<jevin> 	not too hard with hexrays *cough*
[21:03:09]	<Mathieulh>	that's the initial step
[21:03:15]	<Mathieulh>	yeah it's not that hard
[21:03:29]	<Mathieulh>	then you'll figure what a big fuck up the self format really is xD
[21:05:14]	<Mathieulh>	but yeah just my self.cpp is 5 times larger than the entire source for geohot make_self/make_self_npdrm
[21:05:27]	<Mathieulh>	in terms of lines of code
[21:05:48]	<Mathieulh>	so his is missing shitloads of stuffs and only relies on hardcoded values
[21:06:06]	<jevin>	        entire headers copypasta'ed from existing selfs
[21:06:11]	<Mathieulh>	pretty much yah xD
[21:06:23]	<Mathieulh>	the ones on the tool I use are generated
[21:06:32]	<Mathieulh>	as in calculated and generated
[21:06:36]	<Mathieulh>	from the original elf
[21:06:52]	<Mathieulh>	btw unself is buggy too
[21:06:54]	<Mathieulh>	just so you know
[21:07:16]	<jevin>	        why havent you labeled the control flags? :)
[21:08:16]	<Mathieulh>	jevin I didn't feel the need to, I already know what they do anyway
[21:08:37]	<Mathieulh>	for example 0x40 is root rights, 0x20 is debugger rights and so on
[21:09:07]	<jevin>	        im guessing the self capabilities flags are offset 0x20 in the self header
[21:09:18]	<Mathieulh>	capabilities aren't in the header
[21:09:23]	<Mathieulh>	they are part of the metadata
[21:09:28]	<Mathieulh>	as in, they are encrypted and signed
[21:10:16]	<jevin>	        offset 0x10 in the section header?
[21:10:29]	<Mathieulh>	it's after the metadata keys
[21:10:33]	<jevin>	        no, they wouldnt be per section
[21:10:50]	<Mathieulh>	as in, right after them
[21:11:09]	<jevin>	        i see. so unself doesnt have enough fields in the metadata header
[21:11:35]	<jevin>	        i really should color in the hex values that are mapped to structures in unself vs ones that arent
[21:11:42]	<jevin>	        seems like it is missing a lot
[21:11:49]	<Mathieulh>	everything public is missing tons
[21:12:15]	<Mathieulh>	capabilities are optional mind you
[21:12:35]	<jevin>	        are they restrictive or permissive?
[21:13:11]	<Mathieulh>	restrictive
[21:13:16]	<Mathieulh>	(for most)
[21:42:15]	<jevin>	        Mathieulh, you said that the geohot npdrm keypair is blacklisted in 3.56
[21:42:30]	<jevin>	        i couldnt find the decrypted or encrypted metadata keypair in 3.56 files
[21:42:47]	<jevin>	        where does the blacklisting occur? is it a hash that is blacklisted?
[21:43:08]	<jevin> 	its interesting to me because we can make our own keypairs now with juan nadie's work
[21:48:45]	<Mathieulh>	<jevin> Mathieulh, you said that the geohot npdrm keypair is blacklisted in 3.56 <== not only that
[21:49:03]	<Mathieulh>	geohot stuff doesn't generate some of the npdrm specific values
[21:49:08]	<Mathieulh>	those were not checked in 3.55
[21:49:13]	<Mathieulh>	but they are checked in 3.56 now
[21:49:55]	<jevin>	        Mathieulh, gotcha
[21:50:09]	<jevin>	        is his keypair actually blacklisted somewhere though?
[21:50:10]	<Mathieulh>	there is no whitelist for npdrm
[21:50:22]	<Mathieulh>	so it's actually possible to generate valid npdrm self for 3.56+
[21:50:42]	<jevin>	        is it a check in appldr?
[21:50:43]	<Mathieulh>	that tool I made a screenshot of actually does that
[21:51:02]	<Mathieulh>	jevin yeah, it's enforced by lv1 though
[21:51:16]	<jevin>	        a hash comparison?
[21:51:27]	<Mathieulh>	yeah it's a hash
[21:51:30]	<Mathieulh>	but I won't say more
[21:51:35]	<jevin>	        ok :)
[21:51:55]	<Mathieulh>	everything you need is in the 3.56 fw :P
[21:52:16]	<jevin>	        rgr, i will poke around later
[21:52:34]	<jevin>	        the checks are unmodified in 3.60+?
[21:52:43]	<jevin>	        + new keys of course
[21:52:51]	<Mathieulh>	same checks
[21:54:53]	<Mathieulh>	jevin you won't get around crafting valid 3.56+ npdrm selfs without a proper makeself tool though
[21:57:18]	<jevin>	        would SCE make npdrm selfs work if actually signed?
[21:57:25]	<jevin>	        + crypted
