At the moment I have an EC private key in my possession and also some traffic that was encrypted using the aforementioned private key. I have been trying to use OpenSSL to turn the private key into something Wireshark can work with. For example, going from the original:
-----BEGIN EC PRIVATE KEY----- /* BASE 64 ENCODED *\ -----END EC PRIVATE KEY-----
To the following:
-----BEGIN CERTIFICATE----- /* BASE 64 ENCODED */ -----END CERTIFICATE-----
Via the command:
openssl req -new -x509 -key private_key.pem -out server.pem -days 730
However Wireshark doesn't seem to enjoy this either. Is there a way to decrypt ECDSA traffic using wireshark?
