Description

The tool validates the following set of header fields in a DPX file:

• Magic number of 'SDPX' or 'XPDS' for reversed byte order.

• A valid image data offset value.

• Header format version number as 'V2.0'.

• DPX file size in header matches what filesystem shows.

• Encryption key is undefined and therefore image is unencrypted.
