I lost my second password blockchain.com.

I lost my second password.
Using btcrecover, I found the string "Blockchain second password hash, salt, and iter_count in base64".


Blockchain second password hash, salt, and iter_count in base64:
YnM6UtV42SCdSoI1ZU9UkftyxUwwoSysc98fv95J+RN+EveQQqV0cIFB3adB7W4N//FQiBMAANKIkNA=

I want to decode this and extract the second password. Is there a way?

Add information.

I want to revive the second password of blockchain.com.

Current situation,
· It gets garbled when decoding with base64.
· Since I am concerned about + and / contained in the string, I changed the shape.
+→ %2B , / →%2F , = → %3
