Mask French phone number
This function generates a unique random French phone number related to the input.
This function masks the last six digits. Input values that contain at least six digits are regarded as valid phone numbers.
If the input value is not valid, the function returns null.
This function only applies on Strings.
If there are duplicates in the input data, you will get the same duplicates in the masked values. In the same way, if there are no duplicates in the input data, there will be no duplicates in the masked values.
| Option | Description |
|---|---|
| Method |
The default Basic method uses a proprietary
algorithm.
Information noteNote: As the masking methods are stronger, it is recommended to use the FF1
algorithms rather than the Basic method.
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, 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 for FF1 method field, from the Advanced Settings of the component. |
| Extra parameter | This function requires no extra parameter. |
In the following example, the Keep format check box is selected to preserve the spaces from the input value.
| Input value | Method | Example of masked value |
|---|---|---|
| 02 40 99 90 99 | FF1 with AES | 02 40 89 78 01 |
