The Wireshark filter smtp.auth.username does great. The Info column shows the readable username. The same filter in tshark does not interpret the base64 packet content. How can I make it do that?

Pass -o smtp.decryption:TRUE to tshark.

Example without the option:

tshark -T fields -e frame.number -e smtp.auth.username -Y smtp.auth.username -r crim.pcap

Example with the option:

tshark -o smtp.decryption:TRUE -T fields -e frame.number -e smtp.auth.username -Y smtp.auth.username -r crim.pcap
