GooglePrivacyDlpV2CryptoReplaceFfxFpeConfig class

Replaces an identifier with a surrogate using Format Preserving Encryption (FPE) with the FFX mode of operation; however when used in the ReidentifyContent API method, it serves the opposite function by reversing the surrogate back into the original identifier.

The identifier must be encoded as ASCII. For a given crypto key and context, the same identifier will be replaced with the same surrogate. Identifiers must be at least two characters long. In the case that the identifier is the empty string, it will be skipped. See https://cloud.google.com/sensitive-data-protection/docs/pseudonymization to learn more. Note: We recommend using CryptoDeterministicConfig for all use cases which do not require preserving the input alphabet space and size, plus warrant referential integrity.

Properties

commonAlphabet ↔ String?
Common alphabets. Possible string values are:
getter/setter pair
context ↔ GooglePrivacyDlpV2FieldId?
The 'tweak', a context may be used for higher security since the same identifier in two different contexts won't be given the same surrogate.
getter/setter pair
cryptoKey ↔ GooglePrivacyDlpV2CryptoKey?
The key used by the encryption algorithm.
getter/setter pair
customAlphabet ↔ String?
This is supported by mapping these to the alphanumeric characters that the FFX mode natively supports.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
radix ↔ int?
The native way to select the alphabet.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
surrogateInfoType ↔ GooglePrivacyDlpV2InfoType?
The custom infoType to annotate the surrogate with.
getter/setter pair
