we want to obfuscate the credit card numbers
Is there any other option?

If you have DQ License you can try using Data masking transformation. It has a special option for Credit card masking.
MD5 is one of the option to encrypt your data.
Informatica also provides AES_ENCRYPT and AES_DECRYPT functions.
Feed you credit card numbers, with length as 16 string and the aes_encrypt can be captured in an output field of binary type.
See if that works.
