C# 如何从整数生成MD5哈希(32/64个字符)
我已经用谷歌搜索和检查过了 如何从整数生成MD5哈希(32/64个字符) 我得到的是从字符串或字节数组生成MD5哈希字符串的示例。但在我的例子中,我需要从整数中获取MD5哈希 我知道C# 如何从整数生成MD5哈希(32/64个字符),c#,.net,hash,int,md5,C#,.net,Hash,Int,Md5,我已经用谷歌搜索和检查过了 如何从整数生成MD5哈希(32/64个字符) 我得到的是从字符串或字节数组生成MD5哈希字符串的示例。但在我的例子中,我需要从整数中获取MD5哈希 我知道GetHashCode()方法用于获取整数的哈希代码。但这种方法不适用于我的情况 我是否需要将整数转换为字符串或字节数组以获得预期的MD5哈希字符串 请建议我怎么做?你可以试试这个 int intValue = ; // your value byte[] intBytes = BitConverter.GetByt
GetHashCode()

我是否需要将整数转换为字符串或字节数组以获得预期的MD5哈希字符串
请建议我怎么做?你可以试试这个
int intValue = ; // your value
byte[] intBytes = BitConverter.GetBytes(intValue);
Array.Reverse(intBytes);
byte[] result = intBytes; // you are most probably working on a little-endian machine
byte[] hash = ((HashAlgorithm) CryptoConfig.CreateFromName("MD5")).ComputeHash(result);
// string representation (similar to UNIX format)
string encoded = BitConverter.ToString(hash)
// without dashes
.Replace("-", string.Empty)
// make lowercase
.ToLower();
你可以试试这个
int intValue = ; // your value
byte[] intBytes = BitConverter.GetBytes(intValue);
Array.Reverse(intBytes);
byte[] result = intBytes; // you are most probably working on a little-endian machine
byte[] hash = ((HashAlgorithm) CryptoConfig.CreateFromName("MD5")).ComputeHash(result);
// string representation (similar to UNIX format)
string encoded = BitConverter.ToString(hash)
// without dashes
.Replace("-", string.Empty)
// make lowercase
.ToLower();
首先需要将整数转换为字节数组,然后可以执行以下操作:
byte[] hashValue;
using (var md5 = MD5.Create())
{
hashValue = md5.ComputeHash(BitConverter.GetBytes(5));
}

如果你想知道“生命的意义”的md5散列是什么,你可以 这假设您可以
public string CalculateMD5Hash(string input)
{
// step 1, calculate MD5 hash from input
MD5 md5 = System.Security.Cryptography.MD5.Create();
byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);
byte[] hash = md5.ComputeHash(inputBytes);
// step 2, convert byte array to hex string
StringBuilder sb = new StringBuilder();
for (int i = 0; i < hash.Length; i++)
{
sb.Append(hash[i].ToString("X2"));
}
return sb.ToString();
}
公共字符串计算emd5hash(字符串输入)
{
//步骤1,从输入计算MD5散列
MD5 MD5=System.Security.Cryptography.MD5.Create();
byte[]inputBytes=System.Text.Encoding.ASCII.GetBytes(输入);
byte[]hash=md5.ComputeHash(inputBytes);
//步骤2,将字节数组转换为十六进制字符串
StringBuilder sb=新的StringBuilder();
for(int i=0;i

类似这样的内容:
int source = 123;
String hash;
// Do not omit "using" - should be disposed
using (var md5 = System.Security.Cryptography.MD5.Create())
{
hash = String.Concat(md5.ComputeHash(BitConverter
.GetBytes(source))
.Select(x => x.ToString("x2")));
}
// Test
// d119fabe038bc5d0496051658fd205e6
Console.Write(hash);
大概是这样的:
int source = 123;
String hash;
// Do not omit "using" - should be disposed
using (var md5 = System.Security.Cryptography.MD5.Create())
{
hash = String.Concat(md5.ComputeHash(BitConverter
.GetBytes(source))
.Select(x => x.ToString("x2")));
}
// Test
// d119fabe038bc5d0496051658fd205e6
Console.Write(hash);
