I have implemented various block ciphers on various machines, just to
get an idea if transparent harddisk encryption is feasible yet.

The ciphers are DES, FEAL-8 (8 rounds FEAL) and IPES (if it is still
called IPES, there are rumours Prof. Massey changes the name each week).

I wonder if FEAL-8 (by NTT, Japan) is still considered safe.

Any suggestions? - Please send email, I will summarize to the net.

For all who are interested, here is the table (assembly code, of course):

bytes per second          DES          FEAL-8         IPES
Intel486 @ 25 MHz         95000        450000        139000
MIPS R3000 @ 25 MHz      126000        470000        225000
Intel i960CA @ 25 MHz    200000        518000        350000

As you see, if it is still safe, FEAL-8 is a prime candidate for
transparent encryption without hardware gadgets.
