Cryptography – The terms “crypto” and “currency” are combined to form the phrase “cryptocurrency,” as you would have guessed. Despite this, a lot of people are still unsure of what cryptography is and how it relates to cryptocurrencies. Therefore, let’s take a deeper look at cryptography and how it relates to cryptocurrencies.
In essence, cryptography is the process of encrypting certain data or information to protect it from prying eyes. From the allied forces transmitting military signals during World War II to Julius Caesar employing cyphers to convey encrypted messages to his generals in ancient times, cryptography has been utilized for everything.
WHY CRYPTOGRAPHY IS NEEDED
Cryptography is often necessary to prevent the compromise and theft of sensitive data by people who should not see it. These data can be of military, financial, scientific, mathematical, medical, etc. origin. There are an incredible number of reasons why it is necessary for many different people to keep certain information secret.
Some information, if it gets into the wrong sources, can even pose a threat to national security. For example, nuclear launch codes or passwords for entering weapons storage or infectious disease facilities, such as CDC testing facilities and the like, must be kept secret to protect national security. Cryptography allows only the right people to have access to relevant sensitive information.
HOW CRYPTOGRAPHY WORKS
There are many different ways to apply cryptography to data. Before the advent of modern technology, permutation cyphers were used to rearrange the letters in a message. For example, the message NRGEE SRGAS can go through a permutation cypher to change the positions of the letters to GREEN GRASS. This is a very simple use of the concept of cryptography. However, in ancient times it was very popular.
Implementation strategies for data Cryptography have grown considerably more complicated. Now, it is possible to encrypt data in more sophisticated ways than ever before using exceedingly difficult mathematical and computational technology. Modern cryptocurrencies are currently using some of these techniques. Despite its complexity, cryptography always operates on the same fundamental tenet: data is encrypted and its real meaning is concealed so that only a person with the proper authorization may decrypt it.
USE OF CRYPTOGRAPHY IN CRYPTOCURRENCIES
Cryptography is primarily used by cryptocurrencies to manage unit formation, protect the security of transactions, and verify asset transfers. To carry out all of these functions, cryptocurrencies rely on so-called “public key cryptography.”
PUBLIC KEY CRYPTOGRAPHY

Thus, only someone who knows the private key can unlock the public key. To better understand how this works, imagine a metallic blue mailbox often found in public places. Anyone can put mail in these mailboxes, but only the postman has the key to open the mailbox and receive the mail. Cryptocurrency cryptography works in much the same way.
Money can be sent to a public key or location (such as a PO Box), but only those with the private key can access it (Postmen). In the world of cryptocurrencies, each person has a mailbox they may use and a key to unlock it. It enables users to receive and access money without allowing others to do the same. Technology’s wonder, public key cryptography, is revolutionizing online payments.
CRYPTOGRAPHIC PUBLIC KEY VULNERABILITIES
Perhaps the biggest vulnerabilities faced by public key cryptography are people accidentally losing their keys or revealing their private keys to others. If a person loses their private key, they may not be able to recover any funds they may have in their wallet. If a person accidentally reveals their private key information to a third party, that third party could hypothetically gain access to the account and steal all of the bitcoins, litecoins, or other cryptocurrencies in that person’s wallet.
HOW CAN CRYPTOGRAPHY CHANGE IN THE FUTURE?
Cryptocurrency cryptography is currently doing very well for the most part, so this doesn’t look like a major change to the underlying public-key cryptographic structure that’s coming anytime soon. In fact, it seems that more and more people will feel comfortable using cryptocurrencies based on this technology.
However, as technology improves over time, it is possible that someone could come up with a system that is even better than public key cryptography. If this happens, many major cryptocurrencies will likely update to accommodate these developments. Hypothetically, this could make cryptocurrencies even more secure.
But then again, at the moment, public key cryptography is doing very well, and the cryptocurrency industry is booming. Major cryptocurrencies such as Litecoin, Bitcoin, Ethereum, and others have made incredible strides in the past year as their adoption rates have skyrocketed. The cryptography of these public key coins is at the heart of their strength and continues to be an important factor in holding back their growth. It is possible that in the next decade, Bitcoin or even various other cryptocurrencies will begin to seriously compete with the dollar and other fiat currencies backed by fiat.
FINAL THOUGHTS ON CRYPTOGRAPHY
The concept of cryptocurrency has been around for literally millennia. It has been used in different ways by different people for different reasons. Despite the rich history of [cryptography], cryptocurrencies based on public key cryptography are still in their infancy. In fact, the first cryptocurrency (Bitcoin) has only existed for about 9-10 years. The limitless potential of this type of cryptography is just beginning to be realized.
As more and more people start using cryptocurrencies, an increasing percentage of the population will begin to realize how valuable public key [cryptography] and cryptocurrencies are. For anyone who is a fan of crypto, privacy and security, these are very exciting times. One of the reasons all these crypto technologies are being developed is because there is a great need to securely store, send and receive money online.
