示例1: MD5hash
byte[] MD5hash (byte[] data)
{
// This is one implementation of the abstract class MD5.
MD5 md5 = new MD5CryptoServiceProvider();
byte[] result = md5.ComputeHash(data);
return result;
}示例2: getMd5Hash
//引入命名空间
using System;
using System.Security.Cryptography;
using System.Text;
class Example
{
// Hash an input string and return the hash as
// a 32 character hexadecimal string.
static string getMd5Hash(string input)
{
// Create a new instance of the MD5CryptoServiceProvider object.
MD5CryptoServiceProvider md5Hasher = new MD5CryptoServiceProvider();
// Convert the input string to a byte array and compute the hash.
byte[] data = md5Hasher.ComputeHash(Encoding.Default.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(string input, string hash)
{
// Hash the input.
string hashOfInput = getMd5Hash(input);
// Create a StringComparer an compare the hashes.
StringComparer comparer = StringComparer.OrdinalIgnoreCase;
if (0 == comparer.Compare(hashOfInput, hash))
{
return true;
}
else
{
return false;
}
}
static void Main()
{
string source = "Hello World!";
string hash = getMd5Hash(source);
Console.WriteLine("The MD5 hash of " + source + " is: " + hash + ".");
Console.WriteLine("Verifying the hash...");
if (verifyMd5Hash(source, hash))
{
Console.WriteLine("The hashes are the same.");
}
else
{
Console.WriteLine("The hashes are not same.");
}
}
}输出：
The MD5 hash of Hello World! is: ed076287532e86365e841e92bfc50d8c. Verifying the hash... The hashes are the same.
