Cryptography is the term used to describe the use of mathematical techniques for storing, securing, and transforming data. To be an educated user of the world’s most sophisticated tools for privacy and security, it is important to understand both cryptography and computer security. Tutorials will show you how to encrypt information before storing them on your computer or before sending them off into cyberspace. There are also tutorials on digitally signing email messages or files with your chosen private key. You’ll find tutorials teaching you about password cracking, how public key encryption works, setting up your own CA, generation of different types of symmetric keys…

What is cryptocurrency?
Cryptocurrency is a digital or virtual currency, which are called crypto-coins in this case. Cryptocurrencies are issued, or “mined”, by using computers to complete a complicated process called “mining”. In this process, computers are used to solve complex math problems, which become part of the blockchain, a public ledger of transactions that is the basis of all cryptocurrencies. This ledger is also called the “blockchain”, a technology that enables cryptocurrencies. Cryptocurrencies use cryptography, a process that converts data into an unreadable form for humans and computers, but which can be reversed easily. Cryptography enables people to send each other money, without having to go through a financial institution.
Why use cryptocurrency?
Cryptocurrencies are the first decentralised digital currencies. A decentralised currency means that it does not rely on a central authority to keep the system going. In other words, it is not controlled by a central authority, and there is no government or bank that can regulate the transactions of the currency. There is no single point of failure. In a decentralised system, all the information that is required to use the currency is distributed across a large number of computers. There is no single point of failure.
How do you use cryptocurrency?
Cryptocurrency is used to make payments for products and services. When someone buys a product or service using cryptocurrency, it is called a “crypto transaction”. When the person who is selling the product
Cryptocurrency Investing: Pros & Cons
Cryptocurrency investing has seen a huge increase in popularity over the last few years. The fact that it is unregulated by the government and free from banks means that it can be used to purchase all sorts of different products. The pros and cons of investing in cryptocurrency are many. The fact that it is unregulated by the government means that it is free from any financial restrictions. However, it can also be a very risky investment. There is no central authority that can regulate the transactions. Cryptocurrency Investing: Pros & Cons
Cryptocurrency exchanges are a key part of cryptocurrency trading. These are online platforms where you can buy and sell different cryptocurrencies. There are also exchanges that trade cryptocurrency for traditional currencies. These are called “crypto to fiat
History of cryptocurrency
In 1985, the American cryptographer David Chaum invented the concept of electronic cash, an anonymous currency that can be sent to others. In 1995, he implemented it through DigiCash. With this technology, digital currency could be transferred to a recipient without a third party’s permission. It allowed the digital currency to be untraceable by the issuing bank, government or any third party. The NSA published a paper describing a cryptographic electronic cash system. Nick Szabo later described bit gold. Both of these concepts involved proof of work. These systems were intended to be based on the blockchain, but no implementation has been developed for any of them.
In the world of cryptocurrencies, “mining” is a process by which validators of transactions gain new coins by using computer resources. This activity rewards validators by reducing the transaction fee paid to the miners.  The rate at which transactions are validated is being increased by the use of specialized machines such as FPGAs and ASICs, running complex hashing algorithms such as SHA-256 and scrypt. This has caused the price of these specialized machines to skyrocket.  Over time, the increasing cost of the machines required to perform this task has created a situation where validators are no longer rewarded by the system, and where the profitability of mining no longer justifies the cost of investing in the equipment and cooling facilities.

Loss, theft, and fraud
Mt. Gox, the largest bitcoin exchange, was shut down in 2014. It declared bankruptcy because it lost 750,000 bitcoins in the course of their business. This equates to roughly 7% of all bitcoins in existence. The price of a bitcoin fell from over $1,100 in December to below $400 in February. Two federal agents used some of the seized bitcoins to pay for their own expenses. In addition, one agent took bitcoin from the Silk Road Task Force to protect himself during an investigation. A man named Ross Ulbricht (“Dread Pirate Roberts”) was arrested and convicted. He got 6.5 years in federal prison. The case was described in an article by Michael Sullivan on MSNBC.com.
