[C#] MD5/SHA/SHA256/SHA384/SHA512等加密方法
本帖最後由 whitefox 於 2023-5-29 13:29 編輯這裡透過System.Security.Cryptography.HashAlgorithm來實現各種Hash加密演算法
這篇只有加密沒有解密！
PS: 輸出文字前只要加 $ 就可以了using System;
using System.Security.Cryptography;
using System.Text;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
string text = "～沒加密的明文～";
string[] encryptTypes = new[] { "md5", "sha1", "sha256", "sha384", "sha512" };
foreach (string encryptType in encryptTypes)
{
string encryptText = Encrypt(text, encryptType);
Console.WriteLine($@"【{text}】經【{encryptType}】加密後：{encryptText}");
}
}

public static string Encrypt(string value, string encryptType)

using (var hashAlgorithm = HashAlgorithm.Create(encryptType))

//使用hex格式輸出
StringBuilder result = new StringBuilder();
foreach (byte b in buffer)
{
result.AppendFormat("{0:x2}", b);
}
