 /**
- * The Class SHA512Util.
- *
+ * SHA-512是一种安全哈希算法，也称为SHA-2 512，它是SHA-2系列中的一种。
+ * 
+ * <p>
+ * SHA-512是一种密码散列函数，可以将任意长度的数据映射为固定长度的512位（64字节）的散列值。
+ * 
+ * SHA-512由美国国家标准与技术研究院（NIST）于2001年发布，作为美国联邦信息处理标准（FIPS）。它是在SHA-2系列中继SHA-256之后发布的第二种算法。
+ * 
+ * SHA-512的主要用途是用于验证数据的完整性和来源，例如电子邮件、数字签名等。由于其产生的散列值长度较长，因此被认为比SHA-256更安全。然而，由于其计算复杂度较高，因此在某些场景下可能会比SHA-256慢一些。
+ * 
+ * 需要注意的是，SHA-512并不是一种可以解密的算法，它是一种单向散列函数，只能用于将数据加密成固定长度的字符串，无法将加密后的字符串还原为原始数据。因此，在使用SHA-512进行数据加密时，需要谨慎选择合适的密钥和参数，以确保数据的安全性和完整性。
