Hi guys,

I am working on an encryption/decryption vigenere cipher at present. Ive been reading and writing to text files using integer arrays and then modding them together in order to get the...

the length is dependant on the key and message (in a text file) length. Can anyone shed some light on how to encrypt these int arrays to ASCII values and then decrypt back to standard?

Thanks for...

So if i wanted to encrypt plaintext into full ASCII values and then decrypt back to plaintext how would i do this?

I was hoping to mod the plaintext by 255 and then reverse mod back again, but if...

Hi,

I am wanting to reverse mod 128 or 255 on ASCII values, does anyone know how to do this?

Thanks

Thanks for the quick reply. I understand it now.
Many thanks

thanks guys but its still not sinking in tonight :(.

So to map each key character (e.g.10 characters) to my file characters (e.g. 200 characters in total) what do i need to do to change my code?...

I am wanting to add the arrays togther.But why does (i) suddenly jump to 10 from 0 after the 1st key mapping?shouldnt it stay constant?

Thanks

thank you, but i dont think it works.

Here is a snippet of my code:
for ( int i = 0; i < file.length;i+=key.length)
{

for (int k = 0; k <key.length;k++)
{

Hi people,

I am wantng to read a key in as an argument that will duplicate itself to the exact character length as the plaintext , read from a text file.

E.g. key = deceptive

Then i need it...
