FNXBasic

These are all debugged and ready to use.

the 256 scrambles 256 bits across 1024 bits.

The 512 scrambles 512 bit across 2048 bits

The 1024 scrambles 1024 bits across 4096 bits

the output is converted to hexadecimal to avoid control characters in the output.

the 1024 cant decypher 512 or 256 and the 512 can`t decypher 256 they all three work with different block sizes.

Here is the 512

Here is the 1024

I modified the code to extend the key of the 3 cyphers.
they now do a letter substitution on the output hexadecimal.

These latest versions are incompatable with the previous versions.

the previous versions can`t decypher the outputs or load the keys.
