Options:

-cryptokeys=< encryption keys Crypto.json>

-blocksize=< BlockSize >

-bitwindow=< BitWindow >

-compress

-encrypt

-order=<OrderingFile>

-diff (requires 2 filenames first)

-enginedir (specify engine dir for when using ini encryption configs)

-projectdir (specify project dir for when using ini encryption configs)

-encryptionini (specify ini base name to gather encryption settings from)

-extracttomountpoint (Extract to mount point path of pak file)

-encryptindex (encrypt the pak file index, making it unusable in unrealpak without supplying the key)

-compressionformat[s]=<Format[,format2,...]> (set the format(s) to compress with, falling back on failures)

-encryptionkeyoverrideguid (override the encryption key guid used for encrypting data in this pak file)

-sign (generate a signature (.sig) file alongside the pak)

-fallbackOrderForNonUassetFiles (if order is not specified for ubulk/uexp files, figure out implicit order based on the uasset order. Generally applies only to the cooker order)

Decryption:

in UnrealPakTool folder, open/edit Crypto.json.

"EncryptionKey":
  {
      "$type":"2",
      "Name":"null",
      "Guid":"null",
      "Key":"Your Base64 key here"
  },

"Your Base64 key here" paste your generated key (in the middle of " "), save file. then in cmd run:

UnrealPak.exe name_of_your_game-WindowsNoEditor.pak -cryptokeys=Crypto.json
