Dynamics NAV Web Services SOAP <Key>

When ever you READ (or insert) a NAV SOAP Web service, NAV will return a SOAP response with <Key> Value.
E.g.

<Soap:Envelope
    xmlns:Soap="http://schemas.xmlsoap.org/soap/envelope/">
    <Soap:Body>
        <ReadMultiple_Result
            xmlns="urn:microsoft-dynamics-schemas/page/ws_fixedasset">
            <ReadMultiple_Result>
                <ws_FixedAsset>
                    <Key>32;4BUAAAJ7/0YAQQAwADAAMAAwADEAMA==9;5675381140;</Key>
                    <No>FA000010</No>
                    <Description>Mercedes 300</Description>
                    <FA_Class_Code>TANGIBLE</FA_Class_Code>
                    <FA_Subclass_Code>CAR</FA_Subclass_Code>
                    <FA_Location_Code>PROD</FA_Location_Code>
                    <Global_Dimension_1_Code>PROD</Global_Dimension_1_Code>
                    <Global_Dimension_2_Code>VW</Global_Dimension_2_Code>
                    <Budgeted_Asset>false</Budgeted_Asset>
                    <Serial_No>EA 12 394 Q</Serial_No>
                    <Search_Description>MERCEDES 300</Search_Description>
                    <Responsible_Employee>JR</Responsible_Employee>
                    <Inactive>false</Inactive>
                    <Blocked>false</Blocked>
                    <Acquired>true</Acquired>
                    <Last_Date_Modified>2023-12-06</Last_Date_Modified>
                </ws_FixedAsset>
            </ReadMultiple_Result>
        </ReadMultiple_Result>
    </Soap:Body>
</Soap:Envelope>

In the response above there is a <Key> Value. Is there any way to decipher this value to a primary key of a record maybe?

<Key>32;4BUAAAJ7/0YAQQAwADAAMAAwADEAMA==9;5675381140;</Key>
