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

[Andreas Brzesowsky]

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.

I applied your patch to trunk and run the test program I sent earlier [1], which creates some encrypted PDF files in PoDoFo and then tries to read them, and the AESv3 still fails, this time with a different error: Testing aesv3.pdf: Failed with error: PoDoFo encounter an error.
