Local Shared Object envelope
A Local Shared Object file (.SOL) consists of a short header, and then a set of name:value pairs comprising that object. All data in the Local Shared Object file format is AMF - ActionScript Message Format-based, and thus big endian (unlike SWF).
Format
See this table :
| Field | Data Type | Example | Description |
|---|---|---|---|
| Version? | byte[2] | “\x00\xbf” | Unknown |
| Length | uint32_be | “\x00\x00\x00\x25” (37) | Length of the *rest* of the .SOL file (filesize - 6) |
| Signature? | byte[10] | “TCSO\x00\x04\x00\x00\x00\x00” | Unknown |
| Root Object Name | UTF-8 string | “\x00\x06my_sol” (”my_sol”) | Name of the root object (uint16_be length prefixed UTF-8) |
| Padding? | byte[4] | “\x00\x00\x00\x00” | Unknown |
... and then name:value pairs until the end of file, as such:
| Field | Data Type | Example | Description |
|---|---|---|---|
| Name | UTF-8 string | “\x00\x04name” (”name”) | Name of the property |
| Value | AMF - ActionScript Message Format | “\x02\x00\x05value” (”value”) | AMF - ActionScript Message Format value with type code |
| Padding | byte | “\x00” | NULL byte |
