Wireshark has an awesome inbuilt feature which can decrypt any traffic over a selected network card. But there are still multiple ways by which hackers can decrypt SSL traffic and one of them is with the help of Wireshark. You can then disable all DH ciphers.Īlternately, you can limit the supported ciphers on the on the Web server side.How to Decrypt SSL traffic using Wireshark : SSL is one the best way to encrypt network traffic and avoiding men in the middle attacks and other session hijacking attacks. To disable a non- Diffie-Hellman cipher on the client side, using Firefox, type about:config in the location bar and search for DH (as shown below). Note: You might be unable to decrypt the session it a Diffie-Hellman cipher is used. The request and response displays as clear text.

Right click on the stream of the packets and select Follow SSL Stream, as shown below.If you get error run on your key file the following openssl command and try again: Password: The certificate’s password (optional)

Key file: The certificate in pkcs format

Click Edit and configure the parameters as follows:.

In the Wireshark application, select Edit > Preferences > Protocols > TLS > RSA keys list.

If you are capturing a proxy (for example, AppWall Web Application Firewall) and the proxy and the target Web server certificates are different, use the private key of the target (either proxy or Web server) that you want to decrypt.The capture must include the full client and server exchange (the CLIENTHELLO, with Session-ID=0 as part of target SSL session stream and SERVERHELLO exchange) symmetric traffic.

The private key file should only contain the private key, as shown in the following example:Ĭccccccccccccccccccccccccccccccccccccccccc.

(Otherwise, use OpenSSL to convert it to the supported format.)

The private key file must be in the PEM or PKCS12 format.

The private key used to encrypt the data must be available on the system running Wireshark.
