尝试使用AES128算法加密样本数据,在

Android和iOS中使用CBC和PKCS7填充,但结果不同:(

Android代码：

private static final byte[] KEY = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10};

int srcBuffSiz = 1024;

byte[] srcBuff = new byte[srcBuffSiz];

Arrays.fill(srcBuff, (byte)0x01);

SecretKeySpec skeySpec = new SecretKeySpec(KEY, "AES");

Cipher ecipher = Cipher.getInstance("AES/CBC/PKCS7Padding");

ecipher.init(Cipher.ENCRYPT_MODE, skeySpec);

byte[] dstBuff = ecipher.doFinal(srcBuff);

int bytesEncrypted = dstBuff.length;

iOS代码：

// Source buffer

size_t srcBuffSiz = 1024;

unsigned char* srcBuff = new unsigned char[srcBuffSiz];

memset(srcBuff, 0x01, srcBuffSiz);

// Destination buffer

size_t dstBuffSiz = srcBuffSiz + 128;

unsigned char* dstBuff = new unsigned char[dstBuffSiz];

memset(dstBuff, 0x00, dstBuffSiz);

unsigned char keyPtr[kCCKeySizeAES128] = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10};

size_t bytesEncrypted = 0;

CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionPKCS7Padding,

keyPtr, kCCKeySizeAES128,

NULL /* initialization vector (optional) */,

srcBuff, srcBuffSiz, /* input */

dstBuff, dstBuffSiz, /* output */

&bytesEncrypted);

因此,在这两种情况下,我都试图使用预定义的样本密钥加密样本1024字节缓冲区(通常填充0x01值).

iOS中第一个和最后6个字节的加密缓冲区：

ED CC 64 27 A8 99 ... 0C 44 9F EC 34 FC

Android中第一个和最后一个6字节的加密缓冲区：

AE 65 A9 F7 7F 0E ... 1F BD AE 8B 85 ED

任何的想法？

如果我将Cipher.getInstance(“AES / CBC / PKCS7Padding”)替换为Cipher.getInstance(“AES”),那么加密缓冲区的前几个字节将是相同的,但是从第17个字节开始……

iOS版：

ED CC 64 27 A8 99 DA 83 D5 4A B0 03 0F E7 DD A7 35 F2 50 5C 49 47 CC 3B 2F AB D1 61 05
