I have a wireshark capture of implementations of DTLS protocol. I have the PSK and I have converted it to corresponding hex.DTLS uses TLS_PSK_WITH_AES_128_CCM_8 cipher suite.

How can I decrypt the data in wieshark(1.12.7)?


Open the capture on Wireshark, and:

  • Rigth-click on a DTLS packet
  • Then select "Protocol Preferences" --> "Datagram Transport Layer Preferences"
  • There you can put your PSK in HEX format.

Finally, when you select a DTLS packet, on the details section you have a second tab with the decrypted DTLS data.
