+ Twofish cipher algorithm.
+
+ Twofish was submitted as an AES (Advanced Encryption Standard)
+ candidate cipher by researchers at CounterPane Systems. It is a
+ 16 round block cipher supporting key sizes of 128, 192, and 256
+ bits.

- Authenc: Combined mode wrapper for IPsec.
- This is required for IPSec.
+ This is the Deflate algorithm (RFC1951), specified for use in
+ IPSec with the IPCOMP protocol (RFC3173, RFC2394).
+
+ You will most probably want this if using IPSec.
