Comparing and contrasting basic concepts of cryptography
The most common asymmetric algorithms include the Diffie Hellman, which creates a secure session so that symmetric data can flow securely. An example of this would be the L2TP/IPsec VPN. RSA is the commonly used asymmetric algorithm that was the very first of its kind, creating public and private key pairs. Elliptic Curve Cryptography is an asymmetric algorithm used for the encryption of small mobile devices.
Asymmetric – PKI
Asymmetric keys are obtained from a CA. If you are selling products or services with external entities, then you need to obtain your X509s from a public CA, otherwise your internal certificates will not be accepted.
Asymmetric – weak/depreciated algorithms
A SSL should now be depreciated as it is weak; an example of an exploit is the POODLE attack, which is a man-in-the-middle attack that exploits the vulnerabilities of SSL 3.0 and SSL 3.0 (CBC). Asymmetric algorithms should not be using a key whose strength is 2046...
