Found my old key and secret from 2011 but it is in a weird format...

example:

key: (fake key, just alphanumeric format is the same with dashes)
caef74323-1sdg-4g6h-b33r-23523r45ug43

secret: (again, fake, just showing the format)
KSdru780fsfSDHL89fdslkSD98SFJPiufs98sf/QWU9gsmsS89sefiunAISUN89mjds==

You're foolish if you try to decrypt, the key and secret above are 100% fake, just showing the format of the key and secret

Things to note: the key has a few dashes, and the secret ends with "=="

Anyone on here know what this is? or how to decrypt.
Im honestly not even sure if its a wallet, but I do remember tinkering with Bitcoin in 2011
Actual wallet could be empty, but im very interested to see whats inside if it is a wallet.

PS.. if there is a nice sum of BTC in there, I will PM you.

This has a similar dash positions as a blockchain.info "Wallet ID" (separating three sets of four characters between two longer strings).
But it's only as good as a username, you'll still need the password if it's a wallet ID.

I don't know what the secret is for though, looks like 'something' in BASE64 format to me.

The key you posted looks a lot like the account names that blockchain.info used to use. 5 parts, 4byte-2byte-2byte-2byte-6byte. This was used to log into your account there.

The second part you posted is a base64 encoded string based on its characters. It could possibly be your backup to your blockchain.info wallet. Try using a decoder (offline) to see what data it contains, if it is 16 bytes it could be your mnemonic. It could also be plaintext of it.
If the actual thing is much longer than what you just posted (500-700 bytes at least) it could be the encrypted content of your blockchain.info wallet.aes.json file (encrypted bc.i wallet file) and you'll need the password to decrypt it.

Do you know which wallet did you use? I have a feeling someone asked about something similar in the past, but I cannot recall what was that.
Probably some web-wallet, like blockchain.com, but then I think login with that user/wallet ID is obsolete. Or maybe it still works...

Looks obviously like a BASE64 encoded content. Did you try to decode? https://www.base64decode.org/

try this util from https://casascius.wordpress.com/2013/01/26/bitcoin-address-utility/

the guy made physical bitcoins hes reliable but do some research

it should help you decrypt the key

The decryption this tool offers is for BIP38 not for the specific method that blockchain.info wallets used to encrypt the JSON file using AES. The rest of the utilities this library provides are useless for recovering such a file or the account with a company!

Same here the key is for Blockchain.info ID and the secret I think it is a secret key to open your wallet.aes.json file if you forgot your old password you can use your secret key to recover your wallet.

If you don't have the wallet.aes.json file you won't be able to use those keys you have to recover your wallet.

If ever you found your wallet.aes.json file you can download their old tool to decrypt your wallet from this link below

Bitcoin Wallet for Android by Andreas Schildbach creates Base64 encrypted back ups. Are the first characters from the string "U2FsdGVkX1", by any chance? Do you ever remember using this wallet?

If this is the case, then you'll need to use that app to try to recover your back up, and you'll need to either remember your encryption password or try to brute force it.
