@ThreadSafety(level=COMPLETELY_THREADSAFE)
public final class DNLogFieldSyntax
extends LogFieldSyntax<DN>

This class defines a log field syntax for distinguished name values. This syntax allows individual attribute values to be redacted or tokenized within the DNs. If a DN is completely redacted, then the redacted representation will be "redacted={REDACTED}". If a DN is completely tokenized, then the tokenized representation will be "tokenized={TOKENIZED:token-value}", where token-value will be replaced with a generated value.

NOTE: This class, and other classes within the com.unboundid.ldap.sdk.unboundidds package structure, are only supported for use against Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.

                        java.util.Collection<java.lang.String> excludedSensitiveAttributes)

Creates a new DN log field syntax instance that can optionally define specific attributes to include in or exclude from redaction or tokenization. If any include attributes are specified, then only the values of those attributes will be considered sensitive and will have their values tokenized or redacted. If any exclude attributes are specified, then the values of any attributes except those will be considered sensitive. If no include attributes and no exclude attributes are specified, then all attributes will be considered sensitive and will have their values tokenized or redacted.

Parameters:

maxStringLengthCharacters - The maximum length (in characters) to use for strings within values. Strings that are longer than this should be truncated before inclusion in the log. This value must be greater than or equal to zero.

schema - The schema to use in processing. It may optionally be null if no schema should be used.

includedSensitiveAttributes - The set of names and OIDs for the specific attributes whose values should be considered sensitive and should have their values redacted or tokenized by methods that operate on value components. This may be null or empty if no included sensitive attributes should be defined.

excludedSensitiveAttributes - The set of names and OIDs for the specific attributes whose values should not be considered sensitive and should not have their values redacted or tokenized by methods that operate on value components. This may be null or empty if no excluded sensitive attributes should be defined.

                                byte[] pepper,
                                @NotNull
                                ByteStringBuffer buffer)

Appends a tokenized representation of the provided value to the given buffer.

The resulting token will protect the provided value by representing it in a way that makes it at infeasible to determine what the original value was. However, tokenizing the same value with the same pepper should consistently yield the same token value, so that it will be possible to identify the same value across multiple log messages.

Specified by:

tokenizeEntireValue in class LogFieldSyntax<DN>

Parameters:

value - The value for which to generate the token. It must not be null.

pepper - A pepper used to provide brute-force protection for the resulting token. The pepper value should be kept secret so that it is not available to unauthorized users who might be able to view log information, although the same pepper value should be consistently provided when tokenizing values so that the same value will consistently yield the same token. It must not be null and should not be empty.

                                                          ByteStringBuffer buffer)

Appends a completely tokenized representation of the specified field (both field name and value) for a text-formatted log message to the given buffer.

Specified by:

logCompletelyTokenizedFieldToTextFormattedLog in class LogFieldSyntax<DN>

Parameters:

fieldName - The name for the field. It must not be null.

fieldValue - The value to use for the field. It must not be null.

pepper - A pepper used to provide brute-force protection for the resulting token. The pepper value should be kept secret so that it is not available to unauthorized users who might be able to view log information, although the same pepper value should be consistently provided when tokenizing values so that the same value will consistently yield the same token. It must not be null and should not be empty.

buffer - The buffer to which the sanitized log field should be appended. It must not be null.

Appends a completely tokenized representation of the provided value (without a field name, as might be suitable for a value included in a JSON array) for a JSON-formatted log message to the given buffer.

Specified by:

logCompletelyTokenizedValueToJSONFormattedLog in class LogFieldSyntax<DN>

Parameters:

value - The value to be appended to the buffer in tokenized form. It must not be null.

pepper - A pepper used to provide brute-force protection for the resulting token. The pepper value should be kept secret so that it is not available to unauthorized users who might be able to view log information, although the same pepper value should be consistently provided when tokenizing values so that the same value will consistently yield the same token.

buffer - The buffer to which the tokenized value should be appended. It must not be null.

supportsTokenizedComponents

public boolean supportsTokenizedComponents()

Indicates whether this syntax supports tokenizing individual components of the entire value.

Specified by:

supportsTokenizedComponents in class LogFieldSyntax<DN>

Returns:

true if this syntax supports tokenizing individual components of the entire value, or false if not.

valueWithTokenizedComponentsConformsToSyntax

public boolean valueWithTokenizedComponentsConformsToSyntax()

Indicates whether values with one or more tokenized components still conform to this syntax.

Specified by:

valueWithTokenizedComponentsConformsToSyntax in class LogFieldSyntax<DN>

Returns:

true if values with one or more tokenized components still conform to this syntax.

tokenizeComponents

public void tokenizeComponents(@NotNull
                               DN value,
                               @NotNull
                               byte[] pepper,
                               @NotNull
                               ByteStringBuffer buffer)

Appends a string representation of the given value with zero or more of its components tokenized to the provided buffer. If this syntax does not support tokenized components, then the entire value should be tokenized.

The resulting tokens will protect components of the provided value by representing them in a way that makes it at infeasible to determine what the original components were. However, tokenizing the same value with the same pepper should consistently yield the same token value, so that it will be possible to identify the same value across multiple log messages.

Overrides:

tokenizeComponents in class LogFieldSyntax<DN>

Parameters:

value - The value whose components should be tokenized. It must not be null.

pepper - A pepper used to provide brute-force protection for the resulting token. The pepper value should be kept secret so that it is not available to unauthorized users who might be able to view log information, although the same pepper value should be consistently provided when tokenizing values so that the same value will consistently yield the same token. It must not be null and should not be empty.

buffer - The buffer to which the tokenized representation should be appended. It must not be null.
