RSA (Rivest-Shamir-Adleman) needs no introduction, it is well known and most used public-key cryptosystem that governs our digital lives.

I just want to announce the very first release [v0.0.3] of Cryptos-ruby project, a simple and very easy to use Ruby API to manipulate multiple crypto coins.

This is Part 2 of ‘The hard way - Bitcoin’ series and I will start with ’the easy way’ section first because even this gets a bit complex, then will continue with the hard stuff, crafting a Bitcoin transaction from scratch using basic math and cryptography.

This article will present two ways of generating a Bitcoin address: the hard way using simple math and the easy way using an existing Bitcoin library.
