SWZ
- Format Type : Archive
- Endian Order : Little Endian
- Signature : None
Format Specifications
// SWZ file format (by barncastle)
struct Header
{
uint32_BE Checksum;
uint32_BE Seed; // XOR with EncryptionKey
StringEntry Entries[x];
}
struct StringEntry
{
uint32_BE EncodedCompressedSize // XOR'd
uint32_BE EncodedDecompressedSize // XOR'd
uint32_BE Checksum;
