The RSA is an encription algorithm of public key more used in the world. Its security increases exponentially with every bit that we add to the encription key, hence nobody have achieved break its security and maybe nobody do it never. If you want know how are posible the secure bank transactions over Internet, or how can be signed digitally e-mails and documents, besides of other things, follow reading.

RAM memory
In this post I'm going to explain a way of waste the RAM memory instaled in the computer, which affects to a lot of users.
Since some years ago, are being sold computers with 4 or more GB of RAM, but if we use an operating system of 32 bits, it will indicate us that we are using a little less of those 4 GB. Why occurs this? Continue discovering "RAM memory: Why if I have 4GB or more the OS detect less?"

Continue discovering "Could the CAPTCHA of the future distinguish a human from a machine?"
