This repo provides a list of utility modules for common crypto algorithms use for Exohood operations.


  • factory methods to construct an AES-GCM cipher with a 96-bit nonce from the input raw key bytes
  • encrypt & decrypt methods, the output ciphertext is prefixed with the random nonce.


  • factory methods to construct an DES or 3DES cipher from the raw key bytes or hex text
  • encrypt & decrypt methods
  • verify the constructed cipher against the check value

KEK Bundle

Helper class to construct a 3DES key encryption key from a list of components.


Common RSA operations for plugins to use. Targeting use-cases such as key extraction.
