Label*

Default Value: N/A
Example: FPE account

String

Specify a unique label for the account.

Encryption Key*

Default Value: N/A
Example: 

Integer/Expression

The encryption key (16 or 32 characters) used for encrypting and decrypting data.

Tweak Value*

Default Value: 1,2,3,4,5,6,7
Example: 1,2,3,4,5,6,7

String/Expression

Additional randomization parameter that provides different encryption results without changing the key.

FPE Algorithm

Default Value: FF1
Example:FF1

Dropdown

Specify the algorithm for encryption & decryption. Supported algorithms include FF1 & FF3-1.

Note: A value must be decrypted with the algorithm it was encrypted with. If encrypt and decrypt snaps use different accounts, set the same algorithm on both, as a mismatch silently yields wrong data.

Alphabet for Strings*

Default Value: 
Example: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789

String / Expression

The character set (alphabet) used for encrypting string values.

Unicode Alphabet for Strings

Default Value: Not selected
Example: Not selected

Checkbox

This setting is used to enable full Unicode character set (U+0000 to U+FFFF) for string encryption instead of custom alphabet.

Padding Character for Strings*

Default Value: N/A
Example:

String/Expression

Single character used to pad short strings to meet minimum encryption length requirement (must be from the alphabet).

Padding Direction for Strings

Default Value: Right
Example:Left

Dropdown

Direction to apply padding for strings: Left (adds padding at beginning) or Right (adds padding at end).

Alphabet for Numbers*

Default Value: 
Example:0123456789

String

The character set used for encrypting numeric values (typically 0123456789).

Padding Character for Numbers*

Default Value: N/A
Example: 0

String

Single character used to pad short numbers to meet minimum encryption length requirement (typically 0).

Padding direction for Numbers

Default Value: Left
Example:Right

Dropdown

Direction to apply padding for numbers: Left (recommended, e.g., 0012345) or Right (e.g., 12345000).

Date Shift*

Default Value: N/A
Example:20

String

Number of days to shift dates forward (positive) or backward (negative) for date obfuscation (e.g., 30 shifts dates 30 days into future).

Check Decrypt

Default Value: Not selected
Example: Selected

Checkbox

Used to immediately decrypt encrypted values to verify encryption correctness (adds overhead, recommended for development only).
