104This class provides anonymization to SerializedRecord objects. It
105 anonymizes all hostnames, ip addresses and file names/paths
106 that appear in EventRecords gathered from the logs
107 and other system utilities. Such values are hashed using a
108 cryptographically safe one-way-hash algorithm (MD5).
