[vtkusers] encrypt and decrypt the VTK data in memory

[Liu_tj]

Hi,


Is it possible to encrypt VTk data in memory and decrypt it before we begin to use it? For example, I generate a 3D volume and want to store it to file, now I hope to encrypt it before writing to file, and decrypt it before using vtkSTLReader to load it?


Thanks
Liu Peng
