define Package/uencrypt/default/description
  This is a small encrypton/decryption program. It defaults
  to AES-128-CBC, but supports any encryption provided by
  the crypto library. Even though it can be used for
  non-critical* regular encryption and decryption operations,
  it is included here to unencrypt the configuration from mtd
  on some devices.

  * Key and IV are exposed on cmdline

  This variant uses $(1) as crypto provider
