use*_*271 3 c# java hash hmac sha512
在 C# 中
public static string HashToString(string message, byte[] key)
{
byte[] b=new HMACSHA512(key).ComputeHash(Encoding.UTF8.GetBytes(message));
return Convert.ToBase64String(b);
}

我已经基于 c# 代码在 java 中编写了 hashtostring 方法。这是正确的吗?(输出是不同的,因为在这两种情况下每次过程都是动态的。)

使用不同的 C# 编码
public static string SHA512_ComputeHash(string text, string secretKey)
{
var hash = new StringBuilder(); ;
byte[] secretkeyBytes = Encoding.UTF8.GetBytes(secretKey);
byte[] inputBytes = Encoding.UTF8.GetBytes(text);
using (var hmac = new HMACSHA512(secretkeyBytes))
{
byte[] hashValue = hmac.ComputeHash(inputBytes);
foreach (var theByte in hashValue)
{
hash.Append(theByte.ToString("x2"));
}
}
return hash.ToString();
}
