Question 13 Consider SSL with 128-bit AES keys. Using 1024-bit RSA keys would be: Too little security, since they provide about the same security as 80-bit symmetric keys. Overkill, since they provide about the same security as 256-bit symmetric encryption keys. Just about right Way, way too little security. Use 8192-bit keys minimally. Question 14 When checking the digital signature of Bob's message, how is a hash function used? It is used to hash the input to the encryption function. It is used to hash the output of the decryption function. It is used to hash the message; the hash is compared with the decrypted hash value. It is used to hash Bob's public key before decryption; the key is long otherwise
