note right of FOF::__construct
  Constructor

  since: 3.2.0
end note

note right of FOF::encrypt
  Encrypt a string as needed

  since: 3.2.0
  return: string
end note

note right of FOF::decrypt
  Decrypt a string as needed

  since: 3.2.0
  return: string
end note

note right of FOF::getExpandedKey
  Function taken from FOFEncryptAes
changed a little but basically the same
to ensure we get the same passwords (not ideal)
we should use `$this->aes->setPassword(...)` instead
but can't for backwards compatibility issues with already encrypted string

  since: 3.2.0
  return: string
  
  arguments:
    string $key
    int $blockSize
    string $iv
end note

note right of FOF::resizeKey
  Function taken from FOFEncryptAes
changed a little but basically the same
to ensure we get the same passwords (not ideal)
we should use `$this->aes->setPassword(...)` instead
but can't for backwards compatibility issues with already encrypted string

  since: 3.2.0
  return: ?string
