Yea. I looked through this and figured out that this likely means nothing.
The first thing I did was try a cryptogram decoder, the result was
CoOm by mR c2 J k F3L1AkYa AND Ng Wi5TH T1HE SuPER5
I thought that this could have some meaning due to the words "super" "the" and "and" being present. But, I decided to go backwards and do the obvious thing. I took "DbBwnfwLd2RzK3A1TzFtTUVUeIq5GOG1OSCyXSL5", and encoded it with Base64. The result was the string
Man is distinguished, not only by his reason, but by this singular passion from other animals, which is a lust of the mind, that by a perseverance of delight in the continued and indefatigable generation of knowledge, exceeds the short vehemence of any carnal pleasure.
I pasted and searched up this string on google, finding a github page "https://github.com/factor/factor/blob/master/basis/base64/base64-tests.factor" and the wikipedia page to Base64. To which, this puzzle was in the example section of the wikipedia page.
(Note: the github page's name is "base64 tests")
But, if you are still inclined to believe that it means something, you can try looking for yourself. - prove me wrong
