Hello, I want to see plaintext checkin and exucute commands with Merlin Agent but had this issue

there was an error Base64 decoding the PSK:                                                             
illegal base64 data at input byte 0  

Here some info from config

"c2_profile_parameters": {
                "AESPSK": {
                    "dec_key": null,
                    "enc_key": null,
                    "value": "none"
                },

With AES it works fine btw

@A-Lazar-A When using Merlin w/ Mythic, there isn't currently a way to not use AES encryption. However, I can help you see plaintext information, depending on what exactly you want to see.

The issue you are describing is with Merlin itself, not with this http C2 Profile.

I've transferred this issue to the Merlin repo for further discussion and tracking. https://github.com/MythicAgents/merlin/issues/20
