There is VeraCrypt, a fork of TrueCrypt 7.1a. It still works at least on Windows and OS X (I didn't check GNU/Linux).

Tails uses CryptSetup to replace TrueCrypt[0]. Although I find it easier just to do

  sudo cryptsetup open --type tcrypt <file> crypdisk
  sudo mount -t ext4 /dev/mapper/crypdisk <location>
