ignace Posted May 25, 2010 Share Posted May 25, 2010 Get a degree in mathematics. Or a book, but you'll need the degree to understand it Quote Link to comment Share on other sites More sharing options...
Daniel0 Posted May 25, 2010 Share Posted May 25, 2010 The first rule of implementing crypto is don't implement crypto. The fact that you are asking this question shows that you shouldn't implement crypto. No offense. Quote Link to comment Share on other sites More sharing options...

I did this a while back, but it wasn't really encryption i don't think. What I did was give each keyboard value a 2 digit number, and put it into 2 arrays, that way I could encode/decode it.

Mchl Posted May 25, 2010 Share Posted May 25, 2010 That's good enough for some fun, but is far from enough when security is concerned. A substitution cypher like this, can be fairly easy broken with frequency analysis. Quote Link to comment Share on other sites More sharing options...
