我这里的不一致仅仅就如下代码而言
先看代码
+ (NSString *)desEncodeContent:(NSString *)content key:(NSString *)key
{
NSString *ciphertext = nil;
const char *textBytes = [content UTF8String];
NSUInteger dataLength = [content length];
unsigned char buffer[1024];
memset(buffer, 0, sizeof(char));
size_t numBytesEncrypted = 0;
// Byte iv[] = {1,2,3,4,5,6,7,8};
CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt,
kCCAlgorithmDES,
kCCOptionPKCS7Padding,
[key UTF8String],
kCCKeySizeDES,
NULL,
textBytes,
dataLength,
buffer,
1024,
&numBytesEncrypted);
if (cryptStatus == kCCSuccess) {
NSData *data = [NSData dataWithBytes:buffer length:(NSUInteger)numBytesEncrypted];
ciphertext = [[NSString alloc] initWithData:[GTMBase64 encodeData:data] encoding:NSUTF8StringEncoding];
}
return ciphertext;
}
private static String encode(String key, byte[] data) {
try {
DESKeySpec dks = new DESKeySpec(key.getBytes());
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
Key secretKey = keyFactory.generateSecret(dks);
Cipher cipher = Cipher.getInstance(ALGORITHM_DES);
IvParameterSpec iv = new IvParameterSpec("12312312".getBytes());
AlgorithmParameterSpec paramSpec = iv;
cipher.init(Cipher.ENCRYPT_MODE, secretKey, paramSpec);
byte[] bytes = cipher.doFinal(data);
return Base64.encodeToString(bytes, 0);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
不是向量的问题
不知道读者动是iOS还是java, 我是iOS, 我对java DES这个API看不懂, 但是语法什么的没问题, 仿佛Android是加了向量, 其实不然, 我尝试OC加向量,结果是不行.
