Is there a way to ascertain a pair or more of Bitcoin addresses belong to the same wallet on the basis an address pair was used as input for a single transaction?
No.
Assuming that all inputs to a transaction are from the same wallet is often called the 'common input ownership heuristic', but it is possible to create transactions using inputs from various ...

In brief, so-called lightweight wallets have to trust the nodes they communicate with, full-node wallets don't have to trust other nodes.
Bitcoin's creator, Satoshi Nakamoto, wrote about Simplified Payment Verification (SPV):
As such, the verification is reliable as long as honest nodes control the network, but is more
vulnerable if the network is ...

You can do this with 1 transaction, it will get more expensive, but it has nothing to do with whether you use separate addresses or not (or with whether or not you're using BIP32 in any way or form, for that matter).
Bitcoin uses a UTXO model: every transaction has 1 or more inputs, and one or more outputs. Every output creates a UTXO (which you can think ...

The fingerprint could be used as a unique identifier for a key (it is based on the longer hash160 of the key which is frequently used as a unique identifier). However because it is only 4 bytes long, it is not hard to find two different xpubs which have the same fingerprint. We would say that the fingerprint for these two xpubs collide with each other.

It just works fine with the modern versions of the software with no changes necessary. Sync will take anywhere from a few hours to a few days depending on your hardware and connection speed. Make more backups than you think are necessary.

Is there a way I can input more than 1 encrypted private key at a time?
Write a script using OpenSSL
I have hundreds of encrypted private keys I want to check for any btc balance.
You should be prepared that they'll all have zero balance soon after typing them into public websites run by people you don't know anything about. Even if the proprietors are ...

Begin anew via file > new/restore, enter a unique filename and click ok, Follow on-screen instructions for the rest. This time choose p2sh-segwit if the addresses in your blockchain.info wallet begin with 3 or p2pkh if they begin with 1.
Native segwit generates addresses beginning with bc1. I don't think blockchain.info generates native segwit addresses at ...

A mnemonic seed phrase can be used to derive an unbounded number of addresses, so you need to supply some additional information, so that the wallet software will know which addresses to derive.
This additional information includes the derivation pathway, and the address type.
There are some standards developed to specify these variables, see for example ...

This is doable. You can run as many nodes with the same wallets as you want.
I imagine you want to do this because the synchronisation process will be faster on another node?
After the process is done, you will have to copy the complete blockchain data, not the wallet itself.
You might want to consider checking for what your bottleneck is - could be the ...

The only thing you need to spend bitcoins is a Private Key, I recommend that you create a Private Key beeing offline, then import it to Bitcoin Core wallet or Electrum Bitcoin wallet (if you don't want to download the complete blockchain) these are the most secure protocols.
First you need to create a Private Key, it consist on a 32 byte array on HEX format(...

It sounds like you are using the non-segwit sighash algorithm. This is not correct. Segwit uses a different sighash algorithm as defined in BIP 143.
