Is there a class to use to mask credit card numbers? Preferrably, all but
the last 4 numbers

Thanks.

No, it is a server application that write the credit card number to a log
file on the server. We need to mask this number before writing it.

Thanks.

You wouldn't really need a whole class just to replace a single line of code that concatenates 12 asterisks and the last 4 digits of your number, I don't think.
 
Hoo hoo hoo! Looks like we got a live one! Here, wave this tiny ad at it:
