You just need to set a pass phrase to your wallet from blockchain.com and put your passphrase here
https://iancoleman.io/bip39/ to extract private keys to all the address linked to your wallet. And you can even easily sign a message with the help of your private keys online, but I would recommand going with the Electrum method for privacy.
OP doesn't need to worry about privacy with the
https://iancoleman.io/bip39/ tool. He can use it while offline and till be able to generate the private key he requires.
Edit:
OP here is the procedure
1. Get your blockchain.com back up phrase. If you don't have it, Visit your blockchain.com account and got to security center. Click on Back Up again under back up Phrase and copy it
2. Head over to
https://iancoleman.io/bip39. Make sure you are offline before you paste in your Backup phrase
3. Under Generate a random mnemonic select the number depending on how many words you have in your phrase. !2 is usually the default for Blockchain.com wallets
4. Paste your backup phrase inside the
BIP39 Mnemonic box
5. Under
Coin slelect BTC
6. Make sure the
Derivation Path is set at
BIP447. Under
Derived Addresses, cross-check for your BTC address of interest with the corresponding private key.
