|Method||The Randomly method
randomly selects a character. As a result, two identical input values can be
masked with the different output values.
When the same value appears twice in the input data, the Consistently method ensures that the function outputs the same masked value in the same Job execution.
This function can encrypt the output masked values in the same format as the input values, using Format-Preserving Encryption (FPE) methods:
The FPE methods are bijective methods.
The FF1 with AES and FF1 with SHA-2 methods require a password to generate encrypted and repeatable masked values. Those FPE methods do not use a seed.
You can specify this password in the password for FF1 method field, from the Advanced Settings of the component.
This function requires an extra parameter.
The extra parameter is the number of digits to be masked.
In the first example, the input value does not contain any digits, the input value is copied as is to the output.
In the first example, the first two digits are are copied to the output as is. The following ones are masked with random digits.
