So your concept is to move the ancient concept of a codebook into a
database? It is ECB with encryption replaced by a lookup.
The overall security is as strong as what I will call the chaining mode
within and between the messages. By this I mean that is "orcdriffle" always
translates to "telephone" the construct will leak and quickly fall apart.
No Joe i meant more like this
I can see the fruits ceasare called me, but thilty my love it is not
working
Dirty pants wialked in the woods alonge and hungry.could that be
obscure, but she is sexy.
(actual sentence encoded without offset technology)You turn me on kiss
me i can feel you hot, so that is it
Let us say the actual sentence to decode is the last one the
equivalence in the database would be.
1. You turn=Tomorrow
2 .me on=i will
3. kiss me=send a letter
4 i can=the authorities
5. feel=regarding
6. you hot=the ballistic
7. so that=orion missile
8. is it=no further contact
The acual deced message will not encode to.... You turn me on kiss i
can feel you hot, so that is it i t will encode by using four 5
multiplied letters from a meaning 3 sentences earlier with a distance
of 5 between each discard the spaces.
And you get a offset number let us say 946422235 and the word to
encode is number 1. Tomorrow then the program take 1+94622235 and
find the eqvivalent phrase for that offset.
When encoding next phrase you move one step, letter forward in the
sentence that is used for offset. Pick the 5 new letters multiply
them.
Of course the program must handle the whole phrasebase phrasebase
like a circle with no end.
I think it a rather clever idea.

You need some method of convolving the database even within the same
message. I would actually suggest having a look at RC4 to create a double
lookup method, it should be simple to create an effective chaining mode from
ther, but the security will be suspect. For stronger security you'll want to
look at the designs of strong stream ciphers.
