[POSDM] Credit card number masking

Hi Experts

We have a requirement to mask the credit card number on display (i.e. POS workbench) BUT show full card number on data level for BW data processing.

I am able to mask the card number on display through the config below:

Cross Application Component --> Payment Cards --> Make Security Settings for Payment Cards. (Masked Display and Encrypted When Saved)

Appreciate if you can kindly guide me to the setting for allowing to show the full card number on data level.

Moreover, I have searched in the note here that Installation of the encryption library "SAPCRYPTOLIB" is needed. Is it true?

Thanks a lot for your help.
