Converting between the PS3 disc game Formats

My understanding is that the main PS3 disc game formats are: JB folder, decrypted .iso, and encrypted .iso
Where the encrypted .iso is the format that is truest to the original disc and is the one used by Redump.

I have a PS3 .iso dump that fits the hash info from Redump, so I know it was a good dump. I extracted it to the JB format to try it on the emulator RPCS3 and it worked fine.

Can I get the original encrypted .iso from the JB folder (where it matches Redump)?
I do have the game's disc key and an IRD file for it

I can't figure out how to do it. I tried these tools (maybe wrong settings?) but got different MD5 to Redump

Is it a general rule that 3k3y encrypted .iso is different from Redump encrypted .iso?

multiman will rip disc to standard iso or JB folder format. encrypted iso's are needed for ODE hardware (disc drive emulator). if you do not have ODE, dont worry about 3k3y stuff.
 
Format is bad description. Maybe form would be better?

Disc image i.e in *.iso format is how data looks like on real disc. Can be partial encrypted (as it looks on PS3BD-ROM) or decrypted as is decrypting on the fly during copying. Format which would cover all data in intact form which can be found on PS3 disc doesn't exist, so *.iso is as near as we can use today.

"JB Format" is just copying files and folders from such disc.

You cannot because You don't know LBA order, don't have encryption key (IRD have it but You must decompressed it first to get it out, *.ird is junk useless file ;p) and don't know which area was encrypted.

The only ways to get 1:1 copy is putting original game to PC (not all ODD/ODDW can reading PS3BD-ROM) or PS3 and dump it (as disc image of course, i.e in multiMAN additional step is mandatory: turning on direct disc access or else disc image will be decrypted).

Currently You cannot mount and play on PS3 encrypted disc images with PS3 games. None Cobra or Mamba support it.
 
Thank you for the quick response.
So, what does PS3Dec do then? I've seen few people in this forum recommend it and it does ask for keys.
 
@Berion i tried dumping PS3 discs with multiMAN and ManaGunZ, the one that matches redump standard hash is encypted iso created from ManaGunZ, but it doesn't boot because it is encrypted. I wasn't able to dump a decrypted iso using ManaGunZ 1.41, i get an error. Found that iso.enc size created with managunz has the same size of iso created with multiman but they have different hashes, so I assume that the iso created from multiman is a decrypted iso, am I right?

I haven't understood how it works actually. The content on each ps3 disc is the same for each game (and matches redump hash) but can't be played on the fly because it is encrypted? So even the decrypted content for the same disc (your copy, and mine of the same game) is identical, or it differs from the console/drive/ids/keys?
 
Depend how You creating ISO in multiMAN. With Direct Disc Access option on, You can create encrypted disc image, with DDA off (by default), decrypted.

Part of the PS3 BD-ROM is encrypted by key written in hidden area of disc (this area can be read only on PS3 ODD, firmwares of PC ODD doesn't allow read it, so *.iso made on PC can be only encrypted). Sector range which is encrypted is decrypting on the fly during disc image creation or just game launching by PS3 (or if You want it still encrypted, You need do extra steps like in multiMAN).

Encrypted sector range covering some files (encryption is not on filesystem level but disc sector level).

Encrypted images cannot be used on PS3 to playing games from them because Cobra/Mamba and backup managers doesn't support it.
