Tickets are a format used to store an encrypted title key. The format has been updated again since 3DS.
Structure
| Offset | Size | Description |
|---|---|---|
| 0x000 | Y | Signature data |
| Y | 0x2C0 | Ticket data |
Y denotes the total size of the "signature data" section and depends on the signature type.
Signature data
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x4 | Signature type |
| 0x4 | X | Signature |
| 0x4 + X | Padding to align the signature data to 0x40 bytes |
Signature type
| Value | Signature method | Signature size | Padding size |
|---|---|---|---|
| 0x010000 | RSA-4096 PKCS#1 v1.5 with SHA-1 | 0x200 | 0x3C |
| 0x010001 | RSA-2048 PKCS#1 v1.5 with SHA-1 | 0x100 | 0x3C |
| 0x010002 | ECDSA with SHA-1 | 0x3C | 0x40 |
| 0x010003 | RSA-4096 PKCS#1 v1.5 with SHA-256 | 0x200 | 0x3C |
| 0x010004 | RSA-2048 PKCS#1 v1.5 with SHA-256 | 0x100 | 0x3C |
| 0x010005 | ECDSA with SHA-256 | 0x3C | 0x40 |
| 0x010006 | HMAC-SHA1-160 | 0x14 | 0x28 |
The hash for the signature is calculated over the ticket data.
Ticket data
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x40 | Issuer |
| 0x40 | 0x100 | Title key block |
| 0x140 | 0x1 | Ticket Version (Always 2 for Switch (ES) Tickets) |
| 0x141 | 0x1 | Title key type |
| 0x142 | 0x2 | Ticket Version |
| 0x144 | 0x1 | License Type |
| 0x145 | 0x1 | Master key revision |
| 0x146 | 0x2 | Properties Bitfield |
| 0x148 | 0x8 | Reserved |
| 0x150 | 0x8 | Ticket ID |
| 0x158 | 0x8 | Device ID |
| 0x160 | 0x10 | Rights ID |

The title key can be stored as a 16-byte block when tickets are "common" [2.0.0+] with title key type 0, or as a "personalized" RSA-2048 message when title key type is 1. The latter is used for titles requiring stronger licensing (applications, add-on content), while the former (old) method is used for patches.
When RSA is used, this uses an SPL key handle that is initialized with the console-unique RSA-2048 ticket key.
Certificate chain
| Certificate | Signature type | Retail cert name | Debug cert name | Description |
|---|---|---|---|---|
| Ticket | RSA-2048 | XS00000020 | Used to verify ticket signatures using AES title key block ("common" tickets) | |

The CA certificate is issued by 'Root', the public key for which is stored in ES.
