Re: [Podofo-users] what is the status of AES Decrypt/Encrypt

[Andreas B. <and...@do...>]

Hi,

that's weird.
Because if the patch is applied correctly the error message "Error 
AES-decryption data length not a multiple of the key length" does not 
exists anymore
In the patch are these lines:
-        if( lLen % keyLen != 0 )
-            PODOFO_RAISE_ERROR_INFO( ePdfError_InternalLogic, "Error 
AES-decryption data length not a multiple of the key length" );
+        if( lLen % 16 != 0 )
+            PODOFO_RAISE_ERROR_INFO( ePdfError_InternalLogic, "Error 
AES-decryption data length not a multiple of 16" );

So can you please make sure that the patch is correctly applied.
Thanks.

Bye

Andreas
