Subject: AW: [oc] Encryption algorithms map to hardware

Most algorithms don't encrypts that block-size
(except for a 2048-bit RSA, that you wouldn't want to implement)

All the symetric ciphers (DES,AES,RC4,...) have either
fixed block-sizes (64 .. 256 bits) (you could chain a number of them), or
are streaming ciphers.

AES (Rijndael) offers variable block sizes (I'm not sure if 2k is ok)

Have a look at:

Betreff: [oc] Encryption algorithms map to hardware


hey there

Does anybody have idea of how to map encryption
algorithms into hardware? Also, what kind of algorithm
could encypt up to 2048 bit packet?

thanks
