HaiAll. we great to join this forum...
would u help me to make this coding with VB net ?
I have one task about substitution of plain text like this
if I encrypt this word, will result DKUH
description about it :
key=3 (it is how many row)
the length of plaint is 4, so
0 * 3 = ABCD
1 * 3 = DEFG
2 * 3 = KLM
3 * 3 = UV
4 * 3 = H
so the result of cipher from ABCD is DKUH
again, we encrypt this DKUH, this description like this :
1 * 3 GNXK
2 * 3 MTD
3 * 3 CV
4 * 3 H
we will take the new result is HCDK
this method above is some of cryptography algorithm (triangle chain).
I very happy if you are should be help me to make this coding with using vb net. I use that for my paper...
my full thank so.
