C# 计算字符串的 MD5 哈希值

CSharp_Md5Encrypt.cs

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();
