Encryption

Usage: mcrputil encrypt [OPTIONS] <INPUT> <OUTPUT>

Arguments:

  <OUTPUT>  Output folder

  -e, --exclude <EXCLUDE>  Specifies files which should not be encrypted
  -h, --help               Print help information

Step-by-step

1. Make sure your pack is unzipped, and in your pack directory should be a manifest.json
2. ./mcrputil encrypt <path to your unzipped pack directory> <path to your unzipped pack/output directory>
3. A contents.json should now be in your pack/output directory, the key will be displayed in the console after "Encryption finished, key: <your key>"
4. Zip your output directory contents (not the directory itself), and copy your key depending on the software used to <your pack zip file>.key.

For integration into build automation systems, it might be easier to use the --key command line argument with an own supplied key.

  <INPUT>   Input folder
  <OUTPUT>  Output folder
