DIGITAL CURRENCY.

Cryptography is the practice and study of hiding information. It is used to protect sensitive information such as passwords, financial data, and secret messages. It is also used in computer systems to protect data from unauthorized access or disclosure. In a computer, cryptography is used to protect data in transit and at rest.

Every day, we rely on cryptography to protect our data and our privacy. We use cryptography to secure our online transactions and to protect our data when we access our bank or credit cards online. We use cryptography to protect our sensitive information when we send an email or text. We use cryptography to secure our communications, our online data, and our devices.

Cryptography is used in a wide variety of contexts: online banking, online shopping, computer networking, and beyond. It’s also the foundation of the computer and communications technologies we rely on every day. When we use these technologies, we trust that our data—our names, our addresses, our credit card numbers—is being transmitted and received reliably.

Cryptography is the practice of encoding a message in such a way that only those who know the code can understand what the message says, and only those who know the code can recover the message. This is done using the scientific method, and is a very rigorous and time-consuming process. However, once the message has been properly secured, it can never be accessed by anyone other than those who are meant to see it.

Cryptography is used to ensure privacy and prevent unauthorized access, copying, or modification. Cryptography can be used to protect data in transit, at rest, or in storage. It can also be used to verify the integrity of data and verify the identity of the sender.
