Hi Wei, I recently ran across a paper published by Martin Stigge, Henryk Plötz, Wolf Müller, and Jens-Peter Redlich: Reversing CRC - Theory and Practice. Reference http://sar.informatik.hu-berlin.de/research/publications/.
In the paper, they discuss their algorithm for modifying data, and then how to obtain the original CRC by changing the data a bit more. The algorithm requires running CRC from the last bit in the stream forward to the point of tampering (mild hand waiving here. Does Crypto++ allow such an operation (a direction on CRC)?
