练习：计算哈希值

In this exercise session, you are assigned to write some code to calculate cryptographic hashes. Write a program to calculate hashes of given text message: SHA-224, SHA-256, SHA3-224, SHA3-384, Keccak-384 and Whirlpool. Write your code in programming language of choice.

在本练习中，你需要编写一些代码来计算加密哈希值。需要编写程序来计算给定文本信息的不同哈希值：SHA-224，SHA-256，SHA3-224，SHA3-384，Keccak-384 和 Whirlpool。你可以自行选择编程语言来编写代码。
