An open-source utility for decrypting, encrypting and signing PS2/PSX DESR KELF files.
Place them in your home directory (%USERPROFILE%) in the "PS2KEYS.dat" file as a 'KEY=HEX_VALUE' pair. Or place them in your working directory.
decrypt - decrypt and check the signature of kelf files
encrypt <headerid> - encrypt and sign kelf files <headerid>: fmcb, fhdb, mbr
fmcb - for retail PS2 memory cards
dnasload - for retail PS2 memory cards (PSX Whitelist)
fhdb - for retail PS2 HDD (HDD OSD / BB Navigator)
mbr - for retail PS2 HDD (mbr injection).
Note: for mbr, elf should load from 0x100000 and should be without headers:
readelf -h <input_elf> should show 0x100000 or 0x100008
headerless elf creation:
$(EE_OBJCOPY) -O binary -v <input_elf> <headerless_elf>
examples:
kelftool encrypt fhdb input.elf output.kelf
kelftool decrypt input.kelf output.elf
decrypt command will also print useful information about kelf

Note: for arcade units (Namco System 246/256 and Konami Python 1) it is necessary to provide different keys and also additional keys: OVERRIDE_KBIT and OVERRIDE_KC
For DTL units it is necessary to provide different keys (dev keystore). Proto keystore probably was never used.
