pseudonymize

Pseudonymizes fields according to a given method.

Deprecated

This operator will soon be removed in favor of first-class support for functions that can be used in a variety of different operators and contexts.

Synopsis

pseudonymize -m|--method=<string> -s|--seed=<seed> <extractor>...

Description

The pseudonimize operator replaces IP address using the Crypto-PAn algorithm.

Currently, pseudonimize exclusively works for fields of type ip.

-m|--method=<string>

The algorithm for pseudonimization

-s|--seed=<seed>

A 64-byte seed that describes a hexadecimal value. When the seed is shorter than 64 bytes, the operator will append zeros to match the size; when it is longer, it will truncate the seed.

<extractor>...

The list of extractors describing fields to pseudonomize. If an extractor matches types other than IP addresses, the operator will ignore them.

Example

Pseudonymize all values of the fields src_ip and dest_ip using the crypto-pan algorithm and deadbeef seed:

pseudonymize --method="crypto-pan" --seed="deadbeef" src_ip, dest_ip
