#snsinstutions #snsdesignthinkers #designthinking Public key cryptography is a system that uses two keys to encrypt and sign data. One key is public and can be used by anyone, while the other key is private and only known by the sender.  How it works Data encrypted with the public key can only be decrypted with the private key.  Public key cryptography is used to create digital signatures, which are unique codes for each message. Public key cryptography is used to authenticate electronic messages and prevent denial or repudiation by the sender or receiver.
