QuickBMS Script
Notes and Comments
- Table of Content (archive footer) is encrypted with XOR encryption. TOC offset is XORed with 0x123.
- Data seems to be unencrypted and uncompressed.
- IDF extension is probably translated to "Insane Data File".
Encryption Method
Below is example of the code from quickbms script which may be used to decrypt TOC:
for i = 0 < TOC_LENGTH get NEW_BYTE byte XMATH NEW_BYTE "NEW_BYTE ^ TOC_XOR_KEY" XMATH TOC_XOR_KEY "(NEW_BYTE + i + (TOC_XOR_KEY * 5)) & 0xFF"
