Replace all digits

This function masks all digits from the input values.
Option Description
Method The Randomly method randomly selects a character. As a result, two identical input values can be masked with 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:

  • FF1 with AES relies on the Advanced Encryption Standard in CBC mode.
  • FF1 with SHA-2 relies on the secure hash function HMAC-256.

The FPE methods are bijective methods, except when using tweaks.

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 or 256-bit key for FF1 methods field, from the Advanced Settings of the component.

Alphabet Digits is the only alphabet available with the FF1 with AES and FF1 with SHA-2 methods.
Extra parameter

The optional extra parameter is the replacement character.

In the first example, the input value contains no digits. The input value is copied as is to the output.

In the second example, the replacement character is not defined. All digits are masked with random digits.

In the third example, all digits are masked with the defined digit.

Input value Method Extra parameter Example of a masked value
Jack Randomly "" Jack
S1000D Randomly "" S5302D
S1000D Randomly "8" S8888D
