Wireshark · Wireshark-users: Re: [Wireshark-users] Trying to decode sshv2 traffic

[M Holt <m.iostreams@xxxxxxxxx>]

SSH uses Diffie-Hellman key exchange, which creates a shared 'ephemeral' key for encryption. As such, there is no current method of decrypting this type of traffic. For more info, take a look here:

Thank you Jeff.

Do you think we can submit it as a future enhancement?

Dear All,

I captured SSHV2 trace file between two servers, I want to see the
decrypted packets.

Any ideas about how I can decrypt the packets?

I believe it is possible to collect the public keys from both servers,
Is this going to help?

Unfortunately, no.  The SSH dissector in Wireshark is not able to decrypt SSH packets.
