Public key sharing refers to the process of distributing a user’s public key to facilitate secure transactions. In systems utilizing public-key cryptography, each user has a pair of keys: a public key, which can be shared openly, and a private key, which must be kept secret.When someone wants to send funds, they use the recipient’s public key to encrypt the transaction. This encryption ensures that only the person with the corresponding private key can access the funds or transaction details. By sharing public keys, users can confirm their identities and enable secure communications without needing to exchange sensitive information.It is important to remember that public keys do not reveal the associated private keys, making this system secure against unauthorized access. Public key sharing can occur through different mediums, such as online wallets, social media, or other channels, and plays a crucial role in enabling decentralized transactions without involving intermediaries.The ability to share public keys easily enhances overall security and trust in transactions, allowing individuals to engage confidently in financial exchanges.
