Modern ciphers, which make distributed ledgers like blockchain possible, are known as asymmetric ciphers. Asymmetric ciphers use one key, known as the public key, to encrypt information and a second key to decrypt information. These two keys are known as the private and public key cryptography pair. foto text editor
