What are the types of cryptography, and how does cryptography protect cryptocurrencies?
Before modern cryptography, basic cryptography was limited to written documents, where a seemingly nonsensical original message was “decrypted” or decoded to reveal its meaning.
Modern cryptographic systems can be classified into three different types:Secret Key CryptographyAlso known as symmetric cryptography, secret key cryptography uses a single key for encrypting data.
Public Key CryptographyAlso called asymmetric cryptography, public key cryptographic schemes use two keys: a public and a private key.
Phishing is when scammers pretend to be trusted contacts or legitimate companies so they can get your private information.
