For MACsec encrypted data, if I know the keys used for encryption, can I load them anywhere within Wireshark to show the original, 'unencrypted' data ?

I have a setup sending ethernet frames between a transmitter and receiver. The frames are encrypted using MACsec, and the keys are known to me. When using WIRESHARK to decode network traffic, is there any way to view the unencrypted data by providing the encryption keys to the tool ?

Currently the MACsec dissector does not provide this capability. You could enter an enhancement request on our gitlab project while providing as much detail as possible, e.g. what kind of key material you would provide (PSK, or the SAK, etc) in this case.
