Generating the keys for patches[edit | edit source]

00 00 00 00 5F 5F 5F 5F 53 43 45 49 53 59 53 31
  • replace 4 dots with soft id in decimal form, xor with 0x140 key and with cipher patcher key and encrypt with master patcher key to obtain cipher master key for that soft id
  • replace 4 dots with soft id in decimal form, xor with 0x140 key and with hasher patcher key and encrypt with master patcher key to obtain hasher master key for that soft id

Modus Operandi[edit | edit source]

  • Reuses the first 0x1E (30) keys from the 64 available on old syscon format from old ps3 syscon
  • UCMD format, similar to ps4
  • Patch generation differs slightly as well as format
  • SNVS (Secured Non Volatile Storage) regions has an extra layer of crypto, making it 3 layers total, opposite to old ps3 syscon
