N Bases calculator :

To do some calculation with any sort of base on any length, because operation are done with strings and vectors, you can multiply 2 numbers of more than 100 digits and have an exact result! What is it useful for ? Some work was done in this field related to encryption issues, for example a 25 chars base allows to write meaningful sentences, and using a multiplication operation gives a "coded" result, the second multiplicative operand being the key! Of course this is not very efficient but it was part of a few other trials and a first step toward a small coder that is independent from hardware configuration, practically if you want to crypt something you generally need a stream of pseudo random numbers, obtaining a good stream of pseudo random numbers is quite difficult and was the target of many mathematics articles! A good solution is obtained with the Xorshift algorithm ( http://en.wikipedia.org/wiki/Xorshift ) that is fast enough to have its bits manipulated within an array instead of a processor registry, and here we are, we become independent from the hardware, and a text coded now should be ok to decipher in 50 years on a very different hardware as long as we can still read the crypt.
