crl_trace doesn't support anonymization, but that's not the app you want
anyway.  You want crl_to_pcap.  (The "to_pcap" part signifies the output
format.  The input format can be anything coral can read; inputting and
outputting the same format is useful if you want to filter or modify the
packets.)  For example:

crl_to_pcap -Canonymize=cryptopan,keyfile=secret -o out.pcap in.pcap
