Why the f not just post it in plaintext? It's public domain info, and is
only weakly protected even though it doesn't need protection - all this does
is force the reader to waste extra time. Seems a bit pointless to me.

During these early stages of evaluating your Vector Cipher 2, I am
focussing on two aspects for Popular Cryptography Magazine:
I cannot find a place in your software to enter a key of all zeros.
When I tried to encrypt a file with 24 megabytes of ASCII information,
the ciphertext was only 3 kilobytes long.
Do you, adacrypt, have any comment on those two issues?

Are these the right programs to be evaluating?
real_time_encryption_program_mark_2.exe
batch_encryption_program_mark_2.exe
general_encryption_program_mark_2.exe
general_decryption_program_mark_2.exe

It is automated to be unobtrusive so unskilled people can benefit.
That automation disallows anyone to enter the key of all zeros, except
in rare instantiations.

I tried out TrueCrypt. It disallows me to enter the key of all zeros.

Yes, I notice that the automated authentication is about as
trustworthy as on-line slot machines.

Hi,

Yes, these are the right programs alright.

That version does not display any of the internal computations at
runtime that Mark_0 does - it is a working version - it also an exact
copy of Mark_1

I have no idea what a key of all zeros that you mention is and there
is no accomodation in my source code for it - I suspect my cipher is
rejecting something it is not intended to do - it may sound small-
minded but frankly the only thing I want to understand is security of
information that is encrypted by one of the two cipher types (sporadic
mapping to integer points in space) - that I am promoting - I want to
cooperate with you and suggest that if you email me a file of
plaintext - I will encrypt it at my end and compare results - remember
I work in denary all the time - no binary ever - except inside my
computer as machine code - hope to hear from - cheers - Adacrypt
