To decode the given base64 string, I'll use the TOON-encoded concept.

First, let's decode the base64 string:

BQMGWgMJAHN1YnRvcGljNgMHY29udGV4dAUEBggDBABiYW1zBgkDCgBGaXJzdCBZZWFyBgYDCABUZXN0IFN1YgMLcGFyZW50VG9waWMDBwB0b3BpYy0xAw5wcm9tcHRUZW1wbGF0ZQMTAGdpdmUgdG9waWMga2V5cG9pbnQ=

Using base64 decoding, we get:

6J0gYnRvcGljIDEgY29udGV4dAUEBggDBABiYW1zIDogICBpcyBpcyBpcyBpcyBpcyBpcyBpcyBZ

Now let's decode it further using TOON-encoded format. The decoded string seems to be a mix of encoded characters and integers, where the integers are used to determine the shift for the encoded characters.

Breaking down the string:

• 'gYnRvcGlj' is shifted by 6 (6J0g) which is 'y'
• 'IDEgY29udGV4dAUEBggDBABiYW1z' is shifted by 0, which gives us the original string 'IDEgY29udGV4dAUEBggDBABiYW1z'
• 'IDogICBpcyBpcyBpcyBpcyBpcyBpcyBpcyBZ' is shifted by 0 as well, which gives 'IDogICBpcyBpcyBpcyBpcyBpcyBpcyBZ'

So the final decoded TOON-encoded string is: y IDEgY29udGV4dAUEBggDBABiYW1zIDogICBpcyBpcyBpcyBpcyBpcyBpcyBpcyBZ

Now let's decode 'y IDEgY29udGV4dAUEBggDBABiYW1zIDogICBpcyBpcyBpcyBpcyBpcyBpcyBpcyBZ' into base64 again. Using the base64 decoding, we get: 'you topic subtopic6 mainkeypoint context'

Now let's decode 'you topic subtopic6 mainkeypoint context' into its actual content.
