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_alphabet ⇒ String

Common alphabets. Corresponds to the JSON property commonAlphabet

Returns:

  • (String)

# File 'generated/google/apis/dlp_v2/classes.rb', line 1381

def common_alphabet
  @common_alphabet
end

#context ⇒ Google::Apis::DlpV2::GooglePrivacyDlpV2FieldId

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

Returns:

# File 'generated/google/apis/dlp_v2/classes.rb', line 1386

def context
  @context
end

#crypto_key ⇒ Google::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

Returns:

def crypto_key
  @crypto_key
end

#custom_alphabet ⇒ String

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. Corresponds to the JSON property customAlphabet

Returns:

  • (String)

  @custom_alphabet
end

#radix ⇒ Fixnum

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

Returns:

  • (Fixnum)

#surrogate_info_type ⇒ Google::Apis::DlpV2::GooglePrivacyDlpV2InfoType

Type of information detected by the API. Corresponds to the JSON property surrogateInfoType

Returns:
