Encryption: Strengths and Weaknesses of Public-key …

WebSymmetric encryption is also called “secret key” encryption because the key must be kept secret from third parties. Strengths of this method include speed and cryptographic strength per bit of key; however, the major weakness is that the key must be securely shared before two parties may communicate securely.
