# 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
|
||||||
|
