Implement SHA-512 and HMAC using C++.... Please show the entire process if you can.

Implement SHA-512 using C++. Input: An input file contains a message that will be composed of ASCII characters. You may not assume that the message is a specific length, but you may assume that the length of the input string is a multiple of 1024 bits. Output: A 512-bit digest, expressed in hexadecimal. B. Implement HMAC using SHA-512 implemented above as the building block. Input: A key used in HMAC algorithm. The input message that is stored in the file with the given name. Output: After computing the HMAC, convert the result into hexadecimal and print it on the screen. Use all upper-case letters for hexadecimal 'A' through 'F'.
