The practice and study of sending secure, encrypted messages between two or more people are known as cryptography. Cryptography enables anonymous, safe, and “trustless” digital currency transactions without needing a bank or other middleman.

With the help of cryptography, cryptocurrency transactions can be anonymous, secure, and “trustless,” which implies that there is no need for a bank, credit card company, government, or other intermediaries to be present during the transaction. Additionally, cryptography is crucial for more than just digital currency; our computers and the networks connected to them constantly encrypt and decrypt data, from every email you write to every Google search you conduct.

Sensitive data can be sent even across unsafe networks by employing specialized encryption methods. The level of encryption will vary depending on how much protection the data needs. For instance, the security utilized on bitcoin networks differs from that used on conventional personal files (such as contacts).
