Subway Surfers
Subway Surfers is a mobile game developed by Kiloo. All the save files consist of the JSON format right after the header, protected by a SHA-1 hash.
Header
'Length' determines the number of bytes are after the header. The value is little-endian.
| Name | Data Type | Position | Length |
|---|---|---|---|
| Magic | Integer | 0 | 0x4 |
| Hash | SHA-1 | 0x4 | 0x14 |
| Length | Integer | 0x18 | 0x4 |
Hash
The hash is generated from the data starting at the end of the header all the way to the end of the file, and a key. The key is different depending on the type of file it is. When creating a new hash, place the key before the data.
