public final class CryptoDeterministicConfig extends GeneratedMessageV3 implements CryptoDeterministicConfigOrBuilder
Pseudonymization method that generates deterministic encryption for the given
input. Outputs a base64 encoded representation of the encrypted output.
Uses AES-SIV based on the RFC https://tools.ietf.org/html/rfc5297.

getContext()
public FieldId getContext()
A context may be used for higher security and maintaining
referential integrity such that the same identifier in two different
contexts will be given a distinct surrogate. The context is appended to
plaintext value being encrypted. On decryption the provided context is
validated against the value used during encryption. If a context was
provided during encryption, same context must be provided during decryption
as well.
If the context is not set, plaintext would be used as is for encryption.
If the context is set but:
- there is no record present when transforming a given value or
- the field is not present when transforming a given value,
plaintext would be used as is for encryption.
Note that case (1) is expected when an
InfoTypeTransformation is
applied to both structured and unstructured ContentItems.

getSurrogateInfoType()
public InfoType getSurrogateInfoType()
The custom info type to annotate the surrogate with.
This annotation will be applied to the surrogate by prefixing it with
the name of the custom info type followed by the number of
characters comprising the surrogate. The following scheme defines the
format: {info type name}({surrogate character count}):{surrogate}
For example, if the name of custom info type is 'MY_TOKEN_INFO_TYPE' and
the surrogate is 'abc', the full replacement value
will be: 'MY_TOKEN_INFO_TYPE(3):abc'
This annotation identifies the surrogate when inspecting content using the
custom info type 'Surrogate'. This facilitates reversal of the
surrogate when it occurs in free text.
Note: For record transformations where the entire cell in a table is being
transformed, surrogates are not mandatory. Surrogates are used to denote
the location of the token and are necessary for re-identification in free
form text.
In order for inspection to work properly, the name of this info type must
not occur naturally anywhere in your data; otherwise, inspection may either
- reverse a surrogate that does not correspond to an actual identifier
- be unable to parse the surrogate and result in an error
Therefore, choose your custom info type name carefully after considering
what your data looks like. One way to select a name that has a high chance
of yielding reliable detection is to include one or more unicode characters
that are highly improbable to exist in your data.
For example, assuming your data is entered from a regular ASCII keyboard,
the symbol with the hex code point 29DD might be used like so:
\u29ddMY_TOKEN_TYPE.
