RSA Public Key Cryptography - This security page at Georgia Tech is devoted to RSA public key cryptography. ... The article discusses the advantages and disadvantages of encryption and states that encryption can be abused but the benefits far outweigh the risks and that key escrow is not the answer due to its disadvantages.

2.1.3 What are the advantages and disadvantages of public-key cryptography compared with secret-key cryptography? A disadvantage of using public-key cryptography for encryption is speed. There are many secret-key encryption methods that are significantly faster than any currently available public-key encryption method.
