Before you invest in any cryptocurrency, you'll be issued what are called public and private keys. These are long, unique blocks of encryption that identify specific currency holders, and are just one layer of security to ensure the privacy of all transactions.

All cryptocurrency wallets have public and private keys. When you generate a wallet through one of a number of merchants you use the public key to send/receive coins and the private key is used to access the wallet/public key. With a number of wallets, a private key. · The private key is also called symmetric being common for both parties. Private key cryptography is faster than public-key cryptography mechanism.

Public Key. The public key is used to encrypt and a private key is used decrypt the data. The private key is shared between the sender and receiver of the encrypted sensitive information.

· Public / Private Keys Cryptocurrencies Let’s look at how public / private key cryptography works, public and private keys exist as pairs or key pairs. They’re called pairs because the two sets of keys are related to each other. It starts with the private key which is just a number picked at random. · A public key is a derivation of a private key, which can be traced back to a private key but can’t be used to decode it.

Using a similar one-way process — called a hash function — the public key creates a shorter version of itself: the crypto address. · Public Key Cryptography Public key cryptography uses a pair of a public key and a private key to perform different tasks.
