I am working on a project that uses the ASDCP library for R/W MXF files. While I was on the area of encryption/decryption of a DCP, I need to extract IV,CV,Essence(including padding),MIC seperately.

I know that IV,CV are the first 32 bytes of the buffer. But how can i extract the Essence(with padding) ,and the MIC value from the ASDCP databuffer?

Thanks in advance
