ArrayIndexOutOfBoundsException

lokesh kalal
Hi Guys ,
Facing multiple crashes in my application.
Is there somthing we can do to fix this?

Fatal Exception: java.lang.
: src.length=208 srcPos=192 dst.length=16 dstPos=16 length=16
       at java.lang.System.arraycopy(System.java:252)
       at com.android.org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher.processBytes(PaddedBufferedBlockCipher.java:221)
       at com.android.org.bouncycastle.jcajce.provider.symmetric.util.BaseBlockCipher$BufferedGenericBlockCipher.processBytes(BaseBlockCipher.java:1004)
       at com.android.org.bouncycastle.jcajce.provider.symmetric.util.BaseBlockCipher.engineDoFinal(BaseBlockCipher.java:841)
       at javax.crypto.Cipher.doFinal(Cipher.java:1340)

RE: ArrayIndexOutOfBoundsException

In reply to this post by lokesh kalal
You need to provide us with a minimal code example on how you use the Cipher so we can help you. What methods do you call with which buffer length, what version is it, which cipher do you use, what do you want to achieve. It looks like you use doFinal(byte[], int) with a too short output buffer. Did you account for IV block, padding and AE Tag?

Hi 
I am using folllwing class to decrypt the various data packet in a loop.

public class Decryptor {

private Cipher aesDecryptCipher = null;

public byte[] Decrypt(byte[] data) {
byte[] decryptedData = null;
try {
if (aesKeySpec == null)
aesKeySpec = new SecretKeySpec(sessionKey, "AES");
if (aesDecryptCipher == null) {
aesDecryptCipher = Cipher.getInstance("AES", "BC");
aesDecryptCipher.init(Cipher.DECRYPT_MODE, aesKeySpec);
}
decryptedData = aesDecryptCipher.doFinal(data);
} catch (NoSuchAlgorithmException e) {
Logger.d(tag, "NoSuchAlgorithmException: " + e.toString());
} catch (NoSuchPaddingException e) {
Logger.d(tag, "NoSuchPaddingException: " + e.toString());
} catch (InvalidKeyException e) {
Logger.d(tag, "InvalidKeyException: " + e.toString());
} catch (IllegalBlockSizeException e) {
Logger.d(tag, "IllegalBlockSizeException: " + e.toString());
} catch (BadPaddingException e) {
Logger.d(tag, "BadPaddingException: " + e.toString());
} catch (NoSuchProviderException e) {
Logger.d(tag, "aesDecrypt NoSuchProviderException: " + e.toString());
} catch (IllegalStateException e) {
Logger.e(tag, "aesDecrypt IllegalStateException: " + e.toString());
}
return decryptedData;
}

Re: ArrayIndexOutOfBoundsException

Tim Panton new
I saw the same problem and solved it by allocating extra space in the output buffer;

Here is a useful code example I found:

byte[] output = new byte[aes.getOutputSize(plaintext.length)];
