encryption query

[Chakraborty, subhadeep [WHQKH]]

Hi,

 

Can anyone please let me know the type of encryption mechanism is used
to encryption card number in credit_card entity(r656976)? I think it is
not SHA-1/md5 since those are one way and used probably is password
encryption.

 

Also, can we alter the type of encryption to a different type using some
configuration parameters?

 

Thanks & Regards,

Subhadeep
