'''Title metadata''' is a format used to store information about a title (a single standalone game, channel, etc.) and all its installed contents, including which contents they consist of and their SHA1 hashes.
 +
 +
Many operations are done in terms of 64-byte blocks, which means you will often see padding out to the nearest 64-byte boundary at the end of a field.

== Example code application ==
 +
<source lang="c">
 +
typedef unsigned char  u8;
 +
typedef unsigned short u16;
 +
typedef unsigned int  u32;
 +
/* On a 32bit system, long is only 4 bytes- use long long instead */
 +
typedef unsigned long u64;
 +
</source>
 +
<source lang="c">
 +
typedef struct {
 +
  u32 cid; // content id
 +
  u16 index; // # number of the file
 +
  u16  type;
 +
  u64 size;
 +
  u8  hash [20]; //  SHA1 hash content
 +
} content_record; // size: 0x24 bytes
 +
</source>
 +
<source lang="c">
 +
enum sig_type {
 +
      RSA_2048 = 0x00010001,
 +
      RSA_4096 = 0x00010000
 +
};
 +
</source>
 +
<source lang="c">
 +
typedef struct {
 +
        u32 sig_type;
 +
        u8 sig[256];
 +
        u8 fill1[60];
 +
        u8 issuer[64]; // Root-CA%08x-CP%08x
 +
        u8 version;
 +
        u8 ca_crl_version;
 +
        u8 signer_crl_version;
 +
        u8 fill2;
 +
        u64 sys_version;
 +
        u64 title_id;
 +
        u32 title_type;
 +
        u16 group_id; // publisher
 +
        u8 reserved[62];
 +
        u32 access_rights;
 +
        u16 title_version;
 +
        u16 num_contents;
 +
        u16 boot_index;
 +
        u16 fill3;
 +
        content_record contents[num_contents];
 +
} tmd;
 +
</source>
 +
The tmd is then followed by a chain of certificates, where each certificate is of the general form
 +
<source lang="c">
 +
  u32 sig_type;  //
 +
  u8 sig[256];  // 256 for RSA_2048, 512 for RSA_4096
 +
  u8 issuer[32];
 +
  u32 tag;  // identifies what is being signed
 +
  u8 name[64]; // name of thing being signed
 +
  u8 key[...];
 +
</source>
