# icf-reader

Tools for decoding, decrypting and encrypting ICFs

## Usage
```shell
icf-reader <PATH TO ICF>
icf-reader <decrypt | encrypt> <INPUT> <OUTPUT>
```

Encrypting the ICF will also correct CRC checksums, so worrying about the
correct checksum is not needed.

## Building
```
ICF_KEY=<key> ICF_IV=<iv> cargo build --release

ls target/release/icf-reader.exe
```
