Block algorithms typically don't operate the way a cube operates. They
are named a block algorithm because they operate on a single block in,
single block out.
ok per block, it is still "a function (on a set) = ou

Are block algorithms not closer to tensors?
sorry if this sounds stupid though..

lets take PKI out for a moment and talk simple block encryption,
given that you know
a. the message or the 1st few bits in it
b. the set of possible block algorithms used to encrypt
Can you determine session key?
If it would be known to be possible this would not be a algorithm

A bit off the thread...
Ever wondered if one can break PKI given that the 1st request to a server is
mostly GET / in https?
Any ideas?
