C# Generate a random Md5 Hash
How to generate a random Md5 开发者_运维问答hash value in C#?
A random MD5 hash value is effectively just a 128-bit crypto-strength random number.
var bytes = new byte[16];
using (var rng = new RNGCryptoServiceProvider())
{
rng.GetBytes(bytes);
}
// and if you need it as a string...
string hash1 = BitConverter.ToString(bytes);
// or maybe...
string hash2 = BitConverter.ToString(bytes).Replace("-", "").ToLower();
You could create a random string using Guid.NewGuid()
and generate its MD5 checksum.
using System.Text;
using System.Security.Cryptography;
public static string ConvertStringtoMD5(string strword)
{
MD5 md5 = MD5.Create();
byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(strword);
byte[] hash = md5.ComputeHash(inputBytes);
StringBuilder sb = new StringBuilder();
for (int i = 0; i < hash.Length; i++)
{
sb.Append(hash[i].ToString("x2"));
}
return sb.ToString();
}
