Hello, how I can generate a ciphered with no padding?

I'm testing with this: 1234567891234567, I'm waiting this base64 result: QlWHK6ZeJptBBCmDLhOpkGAct0ZDO8jaaOFp9sxMSo0=; but the library returns: QlWHK6ZeJptBBCmDLhOpkA==

Thanks in advance.

I have a question about the Additional Authentication Data. Is it possible to use this library with out using that? For the moment I am just passing in

[NSData new]

If I encrypt, then decrypt, on the same device, things seem to work, but doing this test using 2 different devices and a failure happens in step 8 of the decrypt, which has to do with the authentication tag. So I am wondering if I am using that correctly.

Hi Team,

Need help here, I need to get the cipheredData and authenticationTagData from the object iagData

IAGCipheredData *iagData = [IAGAesGcm cipheredDataByAuthenticatedEncryptingPlainData:ciphertext
                                                              withAdditionalAuthenticatedData:aad
                                                                      authenticationTagLength:IAGAuthenticationTagLength128
                                                                         initializationVector:iv
                                                                                          key:key
                                                                                        error:nil];

Any help appreciated.

In Xcode 8.3 and higher you get nullability warnings for IAGBlockType function parameters.

• (void)getXorBuffer:(IAGUCharType *)buffer
  withBuffer:(IAGUCharType *)value1
  buffer:(IAGUCharType *)value2
  bufferSize:(IAGSizeType)bufferSize
  {
  for (IAGSizeType i = 0; i < bufferSize; i++)
  {
  buffer[i] = (value1[i] ^ value2[i]); //EXC_BAD_ACCESS
  }
  }

Hi, thanks for your work, I wand decrypt a file from Android with aes/gcm/nopadding , the library CCCryptorGCM is perfect but is not public ... how call your library? I don't have the

NSData *aad = [@"AdditionalAuthenticatedData" dataUsingEncoding:NSUTF8StringEncoding];
:

I have only Data, ckey and cIv [16]

CCCryptorStatus cryptStatus = CCCryptorGCM(operation,
kCCAlgorithmAES128,
cKey,
kCCKeySizeAES128,
cIv,
kCCBlockSizeAES128,
nil,
0,
contentData.bytes,
contentData.length,
operationBytes,
tag.bytes,
&tagLength);

Thanks a lot
