Ranked in these QuestionsQuestion Ranking
Pro Completely free
CipherShed is completely free and open source.
Available on Windows, OS X and Linux
Pro Built on top of TrueCrypt
CipherShed is built on top of the famous and now abandoned TrueCrypt and it comes with a lot of things that TrueCrypt had.
Con Difficult to enhance key derivation
Since CipherShed decided to keep the TrueCrypt compatibility, and stick with that format they also have to stick with TrueCrypt's key derivation which was released in 2004 and understandably does not offer the same security that it did when first released.
