Regarding encryption, what practice refers to an application capable of using two encryption algorithms at the same time to encrypt information? - -Parallelization What two attributes of symmetric key encryption are the main benefits of it? - -Fast and strong What size keys are used with the Advanced Encryption Standard (AES)? - -128-bit, 192-bit, and 256- bit What type of encryption uses a key pair in the encryption process, where one half of the pair encrypts and the other decrypts? - -Asymmetric Diffie Hellman is a protocol that can be used to provide what function in the encryption process? - - Key exchange Signing is accomplished by using what type of encryption? - -Hash or one-way encryption Which encryption type is best, symmetric or assymmetric? - -Trick question - neither and both depending on the application. Both have strengths and weaknesses. Most modern dynamic encryption uses a combo of symmetric, asymmetric, and hash encryption, capitalizing on strengths of each When would, if ever, someone need to use a revocation certificate? - -Private key has been compromised, or they simply choose to use a new key pair What type of encryption is used by HTTPS and SSL? - -Symmetric, asymmetric, and hash (one-way encryption)
