The keys are used in tandem too. Either of the two keys can be used in encryption, with the other one used for decryption. It is computationally improbable to determine the private key given only knowledge of the cryptographic algorithm and the public key.
Public key cryptography is most used in three ways, to:
- Secure the message transmission between two parties ...
