Dear Guys,
I am Simone from Rome.

I have a problem. I need to write an algorithm for the encryption of data, and to implement it I need to work with integer numbers of about 100 ciphers (for example I need to make a multiplication between 2 numbers of 70 digits each one).

Do you know a solution?

Thanks,
Simone.

Use a library to do that part for you, something like lint for example.
