C# 密码加密 md5加密 SHA256加密

一、md5加密

using System.Security.Cryptography;
public string EncrytPasswordMD5(string password)  
{  
    using (MD5 md5Hash = MD5.Create())  
    {  
        byte[] inputBytes = Encoding.ASCII.GetBytes(password);  
        byte[] hashBytes = md5Hash.ComputeHash(inputBytes);  
        StringBuilder sb = new StringBuilder();  
        for (int i = 0; i < hashBytes.Length; i++)  
        {  
            sb.Append(hashBytes[i].ToString("X2"));  
        }  
        return sb.ToString();  
    }  
}

二、SHA256加密

using System.Security.Cryptography;
public string EncrytPassword(string password)
        {
            using (SHA256 sHA256 = SHA256.Create())
            {
                byte[] inputBytes = Encoding.ASCII.GetBytes(password);
                byte[] hashBytes = sHA256.ComputeHash(inputBytes);
                StringBuilder sb = new StringBuilder();
                for (int i = 0; i < hashBytes.Length; i++)
                {
                    sb.Append(hashBytes[i].ToString("X2"));
                }
                return sb.ToString();
            }
        }
