Overview

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/dlp/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.

#common_alphabetString

Common alphabets. Corresponds to the JSON property commonAlphabet

Returns:

#contextGoogle::Apis::DlpV2::GooglePrivacyDlpV2FieldId

General identifier of a data field in a storage service. Corresponds to the JSON property context

  @context

#crypto_keyGoogle::Apis::DlpV2::GooglePrivacyDlpV2CryptoKey

This is a data encryption key (DEK) (as opposed to a key encryption key (KEK) stored by KMS). When using KMS to wrap/unwrap DEKs, be sure to set an appropriate IAM policy on the KMS CryptoKey (KEK) to ensure an attacker cannot unwrap the data crypto key. Corresponds to the JSON property cryptoKey

def crypto_key
  @crypto_key
end

#custom_alphabetString

This is supported by mapping these to the alphanumeric characters that the FFX mode natively supports. This happens before/after encryption/decryption. Each character listed must appear only once. Number of characters must be in the range [2, 95]. This must be encoded as ASCII. The order of characters does not matter. The full list of allowed characters is: 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz ~!@#$%^&*()_-+= []|\:;"'<,>.?/ Corresponds to the JSON propertycustomAlphabet`

Returns:

  • (String)

end

#radixFixnum

The native way to select the alphabet. Must be in the range [2, 95]. Corresponds to the JSON property radix

Returns:
