It's Not Rsa

The given cipher file contains the following json data.

{
    "ewfd_sodr": "evgnguextliwcmndypzdnhbshracrnpz",
    "srtosr": {
        "9": "III",
        "x": "IV",
        "b": "I",
        "i8xlec7ro": "B"
    },
    "ix99lnvs": [
        {
            "gebsiqw": "C",
            "ocnqgi": "F"
        },
        {
            "xlbienx": "L",
            "pxksnl": "V"

        "t": "YQ",
        "z": "OS",
        "m": "FE"
    }
}

It’s configure for Enigma Machine.

ewfd_sodr indicates the encrypted flag.
In srtosr are left-hand, middle and right-hand rotor, “B” is reflector.
In ix99lnvs, are ring setting and initial value for left-hand, middle and right-hand rotor.
ixla_gbafg is plugboard.

Put them into CyberChef.

Output was DAWGC TFSPI NNING ANDRO TATIN GROTO RS, so the flag was DawgCTF{spinningandrotatingrotors}.
