The new Hashcard1 dialog has the following fields:

Card Start Position: Position where the credit card number starts into a String. Default value is 1.
Ex.: ABC1234567890123456 => Let’s suppose that Card Start Position is 4.
Card End Position: Position where the credit card number ends into a String. Default value is 16.
Ex.: 1234567890123456ABC => Let’s suppose that Card End Position is 17.
Mask Start Position: Position into a credit card number, where FDM will start masking. Default value is 1.
Ex.: 1234567890123456 => Let’s suppose that Mask Start Position is 4.
Mask End Position: Position into a credit card number, where FDM will start masking. Default value is 16.
Ex.: 1234567890123456 => Let’s suppose that Mask End Position is 14.
Master Key: Custom user key that will be mixed with internal key set as we have in FORMATENCRYPT1. Follow the same rules that we have in the FORMATENCRYPT1.
Custom End Digits: Full sentence of digits that will not be masked in the end of credit card number. The check digit will not be updated.
Ex.: 1234567890123000 => Let’s suppose that Custom End Digits is 00.
PS.:
In case of credit card number haven't a valid size, the number will be encrypted and it will remain invalid and same size number.
In case found null, 0 or 0000000000000000, the field value will not be changed.
