面java的Sha1加密在c#中对应要怎么写

// C# SHA一加密 public string SHA一Encrypt(string pwd) { SHA一 sha一 = SHA一.Create(); byte[] bytes = sha一.ComputeHash(Encoding.Default.GetBytes(pwd)); sha一.Clear(); string result = BitConverter.ToString(bytes); return result; } C#些用加密式： // MD5加密 public string MD5Encrypt(string pwd) { MD5 md5 = MD5.Create(); byte[] bytes = md5.ComputeHash(Encoding.Default.GetBytes(pwd)); md5.Clear(); string result = BitConverter.ToString(bytes); return result; } // SHA二5陆加密 public string SHA二5陆Encrypt(string pwd) { SHA二5陆 sha = SHA二5陆.Create(); byte[] bytes = sha.ComputeHash(Encoding.Default.GetBytes(pwd)); sha.Clear(); string result = BitConverter.ToString(bytes); return result; } // SHA三吧四加密 public string SHA三吧四Encrypt(string pwd) { SHA三吧四 sha = SHA三吧四.Create(); byte[] bytes = sha.ComputeHash(Encoding.Default.GetBytes(pwd)); sha.Clear(); string result = BitConverter.ToString(bytes); return result; } // SHA5一二加密 public string SHA5一二Encrypt(string pwd) { SHA5一二 sha = SHA5一二.Create(); byte[] bytes = sha.ComputeHash(Encoding.Default.GetBytes(pwd)); sha.Clear(); string result = BitConverter.ToString(bytes); return result;
