Looks sort of like Base64, although I do see a rather low-entropy substring:
22c62d8d00a89d36908e9015ae37997d3c7ad246a2c62d8d00a89d36908e9015a1 that might be hexadecimal, and there’s some characters after what would be padding in Base64. It could also just be a coincidence as well.
I receive errors trying to decode it. I tried removing the substring above as well, but no dice.
It does output some binary though, but I do not see any headers I recognize, nor does the
file command in Linux.
After looking for hints, this is weird mix of Base64 and some other hexadecimal or something. Some home-rolled encryption, used by: https://encipher.it/
