Encrypting the credit card numbers does the job quite nicely
numero = 53[Text]CCnum_Encrypted=[url][url][Encrypt seed=8chars][CCnumber] [/Encrypt][/url][/url][/Text] [Text]CCnumber=[Decrypt seed=8chars][unurl][CCnum_Encrypted] [/unurl][/Decrypt][/Text]Replace "8chars" with the seed of your choice (8 characters long), but be sure to keep it secret! (note: in your actual code, there will not be line breaks between the square bracketed units.) The following has worked very well for encrypting and decrypting numbers:
[text]CCnum_Encrypted=[url][url][Encrypt seed=8chars][CCnumber]
[/Encrypt][/url][/url][/Text]
[text]CCnumber=[Decrypt seed=8chars][unurl][CCnum_Encrypted]
[/unurl][/Decrypt][/Text]
