我有很多代码片段,它们使用 AES128 加密数据(如果您提供工作实现,我将非常感激)例如这个:
- (NSData*)AES128EncryptWithKey:(NSString*)key {
// 'key' should be 16 bytes for AES128, will be null-padded otherwise
char keyPtr[kCCKeySizeAES128 + 1]; // room for terminator (unused)
bzero(keyPtr, sizeof(keyPtr)); // fill with zeroes (for padding)
// fetch key data
[key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF8StringEncoding];
NSUInteger dataLength = [self length];
//See the doc: For block ciphers, the output size will always be less than or
//equal to the input size plus the size of one block.
//That's why we need to add the size of one block here
size_t bufferSize = dataLength + kCCBlockSizeAES128;
void* buffer = malloc(bufferSize);
size_t numBytesEncrypted = 0;
CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionECBMode + kCCOptionPKCS7Padding,
keyPtr, kCCKeySizeAES128,
NULL /* initialization vector (optional) */,
[self bytes], dataLength, /* input */
buffer, bufferSize, /* output */
&numBytesEncrypted);
if (cryptStatus == kCCSuccess)
{
//the returned NSData takes ownership of the buffer and will free it on deallocation
return [NSData dataWithBytesNoCopy:buffer length:numBytesEncrypted];
}
free(buffer); //free the buffer;
return nil;
}
之后数据经过base64编码,我使用在线工具将其保存到data.bin
我想做的就是用 OpenSSl 解密这些数据。
但是,当我打电话时
openssl enc -aes-128-ecb -in data.bin -out out.bin -d -pass pass:0123456789123456
它告诉我坏幻数
如果我使用
openssl enc -aes-128-ecb -in data.bin -out out.bin -d -pass pass:0123456789123456 -nosalt
它告诉我解密错误
请帮忙。
