What type of encryption am I looking at.

Before I posted this I looked at a couple pgp examples and they had - and _ in the random letters and number block so it doesn’t look like pgp (as far as I can tell)

Please note the block letters and numbers and the 64 character line are in capital letters. I’m quite sure that wouldn’t have been a mistake and forced all upper case.

I found 3 btc addresses from back in 2013 and they gave a bit of btc in them (.19 btc enough to make me want to get it back). each had a short wallet identifier name. The first one was 1GAME then next line my email addess then below that 1300 random letters and numbers (no spaces or dashes or underscores) after that was a line of 64 random letters and numbers (no spaces or dashes etc).

I know this is something to do with my old accounts at blockchain.info which has become blockchain.com. It would have possibly been some type of backup thing they asked me to save at blockchain.info back in the day? I can’t get in by username and password as I lost the passwords long ago and I wasn’t registered in there to simply get a password reset as it doesn’t work that way. I hope someone can help me somehow work out what these random number blocks mean. (Each is 1300 digits).

If you have an opinion and aren’t a FW scammer please let me know your thoughts.
