Sections

• Some of the leafs contain sections similar in PSP and PS3 consoles. Here is the description of one section, sumarized:

Description	Length	Note
Data	0x10	contains the actual data of the file (either idps or psid)
plaintext public key	0x28	contains the section's public key (without padding)
R	0x14	part of the ecdsa signature pair (r,s)
S	0x14	part of the ecdsa signature pair (r,s)
public key	0x28	ecdsa public key (unknown what this is doing here)
encrypted private key	0x20	encrypted blob that contains the section's private key (with padding)
omac/cmac1	0x10	hash of the previous information in CMAC1/OMAC mode

• No padding in PSP and PSVita Sections !
• Some sections aditionally contain 0x30 random bytes!
• Section 0x80 (SMI) contains minver at offset 0x08-0x0B (size 4 bytes, endian-swapped)
