Revoke list is a Certified File.

Location[edit | edit source]

PS3[edit | edit source]

CoreOS package 3.56+.

RL_FOR_PACKAGE.img/RL_FOR_PROGRAM.img, pkg.srvk/prog.srvk

PSVita[edit | edit source]

In SLB2 partition in PUP and in eMMC:

slb2:prog_rvk.srvk

Decryption[edit | edit source]

See Certified_File#Decryption.

Stucture[edit | edit source]

Contains includes/excludes to be checked by lv1/hypervisor.
Fetched by Updating process to NAND/NOR-Flash as trvk_prg0/1 and trvk_pkg0/1.
So this is basically a list of additional checks for the hypervisor.
Example: if (sce type == 4 & authid = x) then do what flags tell, related with version etc.

See also: Keys, Program Authority Id.

Struct[edit | edit source]

 typedef header {
  uint32_t type;          /* 3 ps3 prog rvk, 4 ps3 pkg rvk, 5 psvita prog rvk */

   struct prog {
    uint64_t version;     /* Revoke List Version */
   };
   struct pkg {
    uint64_t unk_pkg_rvk; /* To check */
   };
  };
  uint32_t entry_count;   /* Number of entries */
  uint8_t padding[0xC];
 } __attribute__((packed)) rvk_header;

Revoke list entries[edit | edit source]

typedef rvk_entry {
  uint32_t program_type;
  uint32_t flags;
  uint64_t version;
  uint64_t program_authority_id;
  uint64_t unknown;
