# RH File

RH are files which contain data about items, skills, resources in table form.

### File Encryption <a href="#file-structure" id="file-structure"></a>

RH files are encrypted with **AES-256**.

AESKey = **gkw3iurpamv;kj20984;asdkfjat1af\0**&#x20;

AESIV = **0xDB0F4940**

AESMode = **ECB**

For the AESKey, that's 31 characters followed by a null terminator. The null terminator is required for the AES cipher to function.

### File structure <a href="#file-structure" id="file-structure"></a>

#### The RH files contain columnName, columnTypes, numRows, numColumns, and rowData. <a href="#the-dnt-files-contain-header-columnsinfo-datainfo-and-endinfo" id="the-dnt-files-contain-header-columnsinfo-datainfo-and-endinfo"></a>

```
rhFile
{
	numRows (int32)
	numColumns (int32)
	columnNames (array of strings)
	columnTypes (array of int32)
	rowData
}
```

### Column Types <a href="#column-type" id="column-type"></a>

```
columnTypes
{
	int32 = 0
	float32 = 1
	string2 = 2
	string = 3
	int64 = 4
}
```

**Value of row cell depends of column type value.**

| Column Type Index | Data Type | Column Name Start                               | Description |
