It's a JSON file and should be readable, you can open the decrypted wallet file (wallet.json) with a text editor and look for WIF private keys in there (51/52 character that starts with 5, K or L).
Do not post them here.
If you see random characters instead of a json format, then it's most likely not decrypted properly, corrupted or the password used was incorrect.
My bad, didn't explain my self right.
The file that was in my pc is wallet.aes.json. I've successfully decrypted it and it has among other things my guid (I believe it's also the "private address"), my wallet address, two keys - priv which is 44 characters and priv_sipa which is 51 characters starting with 5 and also sharedKey.
What can I do with this file, if blockchain.com insists that my password is wrong?
