Cryptography - Kamus Indodax Academy

Cryptography is a branch of mathematics that studies showing and disguising or commonly known as the process of decrypting and encrypting information. In the case of digital assets, these are used on the blockchain system making it impossible for someone to break into or break the chain in the blockchain network. Cryptography is also used by makers of digital asset wallet services to encrypt wallets.

History of cryptography

The word “cryptography” comes from the Greek Kryptos, which means hidden.

The prefix “crypt-” means “hidden” or “vault”, and the suffix “-graphy” means “write”.

The origins of cryptography date back to around 2000 BC, with the practice of Egyptian hieroglyphics. It consists of complex pictograms, the full meaning of which is known only to an elite few.

The first known use of modern ciphers was by Julius Caesar (100 BC to 44 BC), who distrusted his messengers when communicating with his governors and officers. For this reason, he created a system in which each character in his message was replaced by a character three positions before it in the Roman alphabet.

In recent times, Cryptography has turned into a battleground for some of the world’s best mathematicians and computer scientists. The ability to securely store and transfer sensitive information has proven to be a critical factor in success in war and business.

Because the government does not want certain entities inside and outside its country to have access to receive and send hidden information that can threaten national interests, Cryptography has experienced various restrictions in many countries, ranging from restrictions on use. and exporting software to the public to disseminate mathematical concepts that can be used to develop cryptosystems.

However, the internet has enabled the deployment of powerful programs and, more importantly, the techniques underlying Cryptography, so that today many of the most sophisticated cryptosystems and ideas are now in the public domain.
