目录
一、有趣的加密方式
1.1、当铺密码
这种加密算法相当简单:当前汉字有多少笔画出头，就是转化成数字几。
王：该字外面有 6 个出头的位置，所以该汉字对应的数字就是 6；
口：该字外面没有出头的位置，那就是0；
人：该字外面有 3 个出头的位置，所以该汉字对应的数字就是 3；
下面是一段由当铺密码组成的字符：
密文：王夫 井工 夫口 由中人 井中 夫夫 由中大
对应： 67 84 70 123 82 77 125
1.2、猪圈密码
由点和线组成的形状即代表在该形状内的那个字↓↓↓↓
由此可以得到密码表↓↓↓↓
例如：the weather is sunny加密后就得到了
1.3、键盘密码
电脑键盘上多个字符表示一个字母，例如9IKLP0代表字母O。
如图，9IKLP0字符围绕中间的字符是O。

基础分享C#封装的几个加解密类
前段时间一个业余项目涉及到字符串和文件的加密，所以写了封装了几个给予DES,AES,MD5的加密解密类.
直接看代码
DesSecurity.cs
/// <summary> /// 基于DES加密解密 /// </summary> public static class DesSecurity { public static byte[] Encrypt( byte[] data ,string key , bool ispaddingzeros = true, bool isEcbMode = true ) { byte[] result; using (DESCryptoServiceProvider des = new DESCryptoServiceProvider { Key = Encoding.Default.GetBytes(key), IV = Encoding.Default.GetBytes("visonsec"), Mode = isEcbMode ? CipherMode.ECB : CipherMode.CBC, Padding = ispaddingzeros ? PaddingMode.Zeros : PaddingMode.None }) { byte[] array; using(MemoryStream ms = new MemoryStream()) { using(CryptoStream cryptoStream = new CryptoStream( ms , des.CreateEncryptor(), CryptoStreamMode.Write)) { cryptoStream.Write(data, 0, data.Length); cryptoStream.FlushFinalBlock(); } array = ms.ToArray(); } result = array; } return result; } public static string Encrypt( string data, string key ) { byte[] bytes = Encoding.Default.GetBytes(data); byte[] valuetocon = DesSecurity.Encrypt(bytes , key, true ,true ); return StringConverter.ToHexString(valuetocon); } public static byte[] Descrypt( byte[] data ,string key , bool ispaddingzeros = true , bool isecbmode = true ) { byte[] result; using(DESCryptoServiceProvider des = new DESCryptoServiceProvider{ Key = Encoding.Default.GetBytes(key), IV = Encoding.Default.GetBytes("visonsec"), Mode= isecbmode ? CipherMode.ECB : CipherMode.CBC , Padding = ispaddingzeros ? PaddingMode.Zeros:PaddingMode.None }) { byte[] array; using (MemoryStream ms = new MemoryStream()) { using( CryptoStream cs = new CryptoStream( ms , des.CreateDecryptor(), CryptoStreamMode.Write)) { cs.Write(data, 0, data.Length); cs.FlushFinalBlock(); } array = ms.ToArray(); } result = array; } return result; } public static string Descrypt(string data , string key ) { byte[] datas = StringConverter.ToHexBytes(data); byte[] bytes = DesSecurity.Descrypt(datas, key, true, true); return Encoding.Default.GetString(bytes).Replace("\0", null); } }
AESSecurity.cs
public static class AESSecurity { public static byte[] Encrypt(byte[] data, string key) { Rijndael rijndael = Rijndael.Create(); rijndael.Mode = CipherMode.ECB; rijndael.Padding = PaddingMode.PKCS7; rijndael.Key = Encoding.UTF8.GetBytes(key); byte[] result; try { using(MemoryStream ms = new MemoryStream()) { using(CryptoStream cs = new CryptoStream(ms,rijndael.CreateEncryptor(), CryptoStreamMode.Write)) { cs.Write(data, 0, data.Length); cs.FlushFinalBlock(); result = ms.ToArray(); } } } catch (Exception ex) { System.Diagnostics.Debug.WriteLine("AES EXCEPTION:" + ex.Message); result = null; } finally { rijndael.Clear(); } return result; } public static byte[] Encrypt(string data, string key) { return AESSecurity.Encrypt(Encoding.UTF8.GetBytes(data), key); } public static byte[] Descrypt(byte[] data ,string key ) { Rijndael rijndael = Rijndael.Create(); rijndael.Mode = CipherMode.ECB; rijndael.Padding = PaddingMode.PKCS7; rijndael.Key = Encoding.UTF8.GetBytes(key); byte[] result; try { using(MemoryStream ms = new MemoryStream()) { using(CryptoStream cs = new CryptoStream(ms, rijndael.CreateDecryptor() , CryptoStreamMode.Write)) { cs.Write(data, 0, data.Length); cs.FlushFinalBlock(); result = ms.ToArray(); } } } catch (Exception e) { result = null; System.Diagnostics.Debug.WriteLine(e.Message); } finally { rijndael.Clear(); } return result; } }
MD5Security.cs
byte[] buf = StringConverter.ToBytes(value); string result; using(MD5CryptoServiceProvider md = new MD5CryptoServiceProvider()) { byte[] v = md.ComputeHash(buf); string s = BitConverter.ToString(v, 4, 8).Replace("-", string.Empty); result = s; } return result; } public static string Encrypt32( string value ) { if (value == null) throw new ArgumentNullException("value"); byte[] buf = StringConverter.ToBytes(value); string result = null; using(MD5CryptoServiceProvider md = new MD5CryptoServiceProvider()) { byte[] array = md.ComputeHash(buf); StringBuilder sb = new StringBuilder(); for(int i = 0 ; i < array.Length ; i++ ) { sb.Append(array[i].ToString("x2")); } result = sb.ToString(); } return result; } public static string GetMD5FromFile( string file ) { if(File.Exists(file)) { string result; using(FileStream fs = new FileStream(file,FileMode.Open)) { using(MD5CryptoServiceProvider md = new MD5CryptoServiceProvider()) { byte[] array = md.ComputeHash(fs); StringBuilder sb = new StringBuilder(); for( int i = 0 ; i < array.Length ; i++ ) { sb.Append(array[i].ToString("x2")); } result = sb.ToString(); } } return result; } else { return null; } } }
StringConverter.cs 字符串转换辅助类
[System.Flags] public enum StringEncodeType { EN_Default = 0 , EN_UTF8 = 1 , EN_UnicodeEncoding = 2 , EN_Base64 = 3 } public static class StringConverter { public static string ToHexString(byte[] valueToConvert) { if (valueToConvert == null) { throw new ArgumentNullException(); } string text = string.Empty; for (int i = 0; i < valueToConvert.Length; i++) { text += valueToConvert[i].ToString("X2"); } return text; } public static byte[] ToHexBytes(string valueToConvert) { if (valueToConvert == null) { throw new ArgumentNullException("valueToConvert"); } valueToConvert = valueToConvert.Replace(" ", string.Empty); if (valueToConvert.Length % 2 != 0) { throw new FormatException("valueToConvert"); } byte[] array = new byte[valueToConvert.Length / 2]; for (int i = 0; i < array.Length; i++) { array[i] = Convert.ToByte(valueToConvert.Substring(i * 2, 2), 16); } return array; } public static byte[] ToBytes(string valueToConvert, StringEncodeType stringEncodingType) { if (valueToConvert == null) { throw new ArgumentNullException("valueToConvert"); } byte[] result = null; switch (stringEncodingType) { case StringEncodeType.EN_Default: result = Encoding.Default.GetBytes(valueToConvert); break; case StringEncodeType.EN_UTF8: result = Encoding.UTF8.GetBytes(valueToConvert); break; case StringEncodeType.EN_UnicodeEncoding: result = new UnicodeEncoding().GetBytes(valueToConvert); break; case StringEncodeType.EN_Base64: result = Convert.FromBase64String(valueToConvert); break; } return result; } public static byte[] ToBytes(string valueToConvert) { return StringConverter.ToBytes(valueToConvert, StringEncodeType.EN_UTF8); } }
