Hi Group,
I having some trouble with a compile, and I want to get this correct:
I have a private class member. It could be any symmetric:
BlockCipher* m_cipher;
At construction:
m_cipher = new
Later, in a method (before any information is encrypted/decrypted) _when_
choosing ECB or CBC mode:
StreamTransformationFilter(
*((SymmetricCipher*)m_cipher), NULL );
StreamTransformationFilter needs a StreamTransformation&.
I don't think it is going to work, since BlockCipher inherits from
BlockTransformation and SimpleKeyingInterface.
How can I attach a filter (when in ECB or CBC mode) to get the effect I
want?
Thanks,
Jeff
For reference, BlockCipher class heirarchy:
