示例1: Main
//引入命名空间
using System;
using System.Security.Cryptography;
using System.Text;
namespace MD5Sample
{
class Program
{
static void Main(string[] args)
{
string source = "Hello World!";
using (MD5 md5Hash = MD5.Create())
{
string hash = GetMd5Hash(md5Hash, source);
Console.WriteLine("The MD5 hash of " + source + " is: " + hash + ".");
Console.WriteLine("Verifying the hash...");
if (VerifyMd5Hash(md5Hash, source, hash))
{
Console.WriteLine("The hashes are the same.");
}
else
{
Console.WriteLine("The hashes are not same.");
}
}
}
static string GetMd5Hash(MD5 md5Hash, string input)
{
// Convert the input string to a byte array and compute the hash.
byte[] data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(input));
// Create a new Stringbuilder to collect the bytes
// and create a string.
StringBuilder sBuilder = new StringBuilder();
// Loop through each byte of the hashed data
// and format each one as a hexadecimal string.
for (int i = 0; i < data.Length; i++)
{
sBuilder.Append(data[i].ToString("x2"));
}
// Return the hexadecimal string.
return sBuilder.ToString();
}
// Verify a hash against a string.
static bool VerifyMd5Hash(MD5 md5Hash, string input, string hash)
{
// Hash the input.
string hashOfInput = GetMd5Hash(md5Hash, input);
// Create a StringComparer an compare the hashes.
StringComparer comparer = StringComparer.OrdinalIgnoreCase;
if (0 == comparer.Compare(hashOfInput, hash))
{
return true;
}
else
{
return false;
}
}
}
}输出：
The MD5 hash of Hello World! is: ed076287532e86365e841e92bfc50d8c. Verifying the hash... The hashes are the same.
