AES不同语言加密解密

AES不同语言加密解密

AES加密模式和填充方式：还有其他

算法/模式/填充 16字节加密后数据长度 不满16字节加密后长度AES/CBC/NoPadding 16 不支持AES/CBC/PKCS5Padding 32 16AES/CBC/ISO10126Padding 32 16AES/CFB/NoPadding 16 原始数据长度AES/CFB/PKCS5Padding 32 16AES/CFB/ISO10126Padding 32 16AES/ECB/NoPadding 16 不支持AES/ECB/PKCS5Padding 32 16AES/ECB/ISO10126Padding 32 16AES/OFB/NoPadding 16 原始数据长度AES/OFB/PKCS5Padding 32 16AES/OFB/ISO10126Padding 32 16AES/PCBC/NoPadding 16 不支持AES/PCBC/PKCS5Padding 32 16AES/PCBC/ISO10126Padding 32 16

更多关于加密模式内容：- 因为数据长度不是16的整数倍就需要填充），而Java是没

有这种填充模式，杯具的只能自己写一个了，那Java的填充模式就用NoPadding（不填充内容）

Java端代码：

import javax.crypto.Cipher;import javax.crypto.spec.IvParameterSpec;import javax.crypto.spec.SecretKeySpec;import sun.misc.BASE64Decoder;public class Encryption{ public static void main(String args[]) throws Exception { System.out.println(encrypt()); System.out.println(desEncrypt()); } public static String encrypt() throws Exception { try { String data = "Test String"; String key = "1234567812345678"; String iv = "1234567812345678"; Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding"); int blockSize = cipher.getBlockSize(); byte[] dataBytes = data.getBytes(); int plaintextLength = dataBytes.length; if (plaintextLength % blockSize != 0) { plaintextLength = plaintextLength + (blockSize - (plaintextLength % blockSize)); } byte[] plaintext = new byte[plaintextLength]; System.arraycopy(dataBytes, 0, plaintext, 0, dataBytes.length); SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES"); IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes()); cipher.init(Cipher.ENCRYPT_MODE, keyspec, ivspec); byte[] encrypted = cipher.doFinal(plaintext); return new sun.misc.BASE64Encoder().encode(encrypted); } catch (Exception e) { e.printStackTrace(); return null; } } public static String desEncrypt() throws Exception { try { String data = "2fbwW9+8vPId2/foafZq6Q=="; String key = "1234567812345678"; String iv = "1234567812345678"; byte[] encrypted1 = new BASE64Decoder().decodeBuffer(data); Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding"); SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES"); IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes()); cipher.init(Cipher.DECRYPT_MODE, keyspec, ivspec); byte[] original = cipher.doFinal(encrypted1); String originalString = new String(original); return originalString; } catch (Exception e) { e.printStackTrace(); return null; } }}

Java的填充模式是NoPadding，用自己的编写的补零填充内容；

php：

';//解密$encryptedData = base64_decode("2fbwW9+8vPId2/foafZq6Q==");$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $privateKey, $encryptedData, MCRYPT_MODE_CBC, $iv);echo($decrypted);?>

C# 最喜欢的语言

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Security.Cryptography;namespace pda_demo{ class Program { static void Main(string[] args) { String encryptData = Program.Encrypt("Test String", "1234567812345678", "1234567812345678"); Console.WriteLine(encryptData); String decryptData = Program.Decrypt("2fbwW9+8vPId2/foafZq6Q==", "1234567812345678", "1234567812345678"); Console.WriteLine(decryptData); Console.Read(); } public static string Encrypt(string toEncrypt, string key, string iv) { byte[] keyArray = UTF8Encoding.UTF8.GetBytes(key); byte[] ivArray = UTF8Encoding.UTF8.GetBytes(iv); byte[] toEncryptArray = UTF8Encoding.UTF8.GetBytes(toEncrypt); RijndaelManaged rDel = new RijndaelManaged(); rDel.Key = keyArray; rDel.IV = ivArray; rDel.Mode = CipherMode.CBC; rDel.Padding = PaddingMode.Zeros; ICryptoTransform cTransform = rDel.CreateEncryptor(); byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length); return Convert.ToBase64String(resultArray, 0, resultArray.Length); } public static string Decrypt(string toDecrypt, string key, string iv) { byte[] keyArray = UTF8Encoding.UTF8.GetBytes(key); byte[] ivArray = UTF8Encoding.UTF8.GetBytes(iv); byte[] toEncryptArray = Convert.FromBase64String(toDecrypt); RijndaelManaged rDel = new RijndaelManaged(); rDel.Key = keyArray; rDel.IV = ivArray; rDel.Mode = CipherMode.CBC; rDel.Padding = PaddingMode.Zeros; ICryptoTransform cTransform = rDel.CreateDecryptor(); byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length); return UTF8Encoding.UTF8.GetString(resultArray); } }}

js：

java 补零操作：

public static String paddingZero(int num, int length) { String s = "" + num; while(s.length()
