Is there a Mathematician Cryptographr in the House.
Both ‘Key’ and ‘Plaintext’ belong in the ASCII printable subset (elements 32 to 126 incl – 95 elements) Treat these names ‘Key’ and ‘Plaintext’ as variable names in this model. X is a positive integer. Consider now, [(X +Key) + (X +Plaintext)] (Mod N) = a residue (Mod N) Call, [(X +Key) + (X +Plaint... 21 Jul 2010 19:08

The Huge Significance of the Newline Character in modern Cryptography.
>> There is nothing preventing you from applying your ideas about using the Vigen�re square in a 256 x 256 form so it can cover all possible bytes, not just a subset of them. �As it is your system is not guaranteed to reproduce what was initially put into it. �For example, here is a short Java program: ... 14 Jul 2010 15:26
