Feature Request: Import private keys with Passphrase option

When importing private keys, try to implement an option to use a passphrase.

A passphrase is typically used in conjunction with a mnemonic phrase (seed phrase), not with a private key directly. It acts as an additional layer of security, often referred to as the "25th word," and is used to access a completely different set of addresses from the same seed phrase. This feature is commonly used in hierarchical deterministic (HD) wallets to enhance security and privacy. If you have any more questions or need further clarification, feel free to ask!

Hi, Yes, BIP38 is a different concept from the "25th word" passphrase used in BIP39 HD wallets. - BIP38 is specifically for encrypting private keys with a passphrase. It is commonly used to secure paper wallets by encrypting private key with a passphrase, making it safer to store or share. The encrypted key can only be decrypted with the correct passphrase. - BIP39 Passphrase ("25th word") is an optional feature in mnemonic seed-based wallets, where an additional passphrase is used alongside the 12/24-word seed phrase to generate a completely different wallet. This enhances security by making the mnemonic useless without the passphrase. So, while both involve passphrases, BIP38 encrypts a single private key, whereas BIP39 modifies the derived keys from a mnemonic seed. *Comparison: BIP38 vs. BIP39* Feature*BIP38**BIP39* *Purpose* Encrypt private keys with a passphrase Create mnemonic phrases for HD wallets *Format* Single private key encryption 12/24-word seed phrases *Security* Requires a passphrase to decrypt Optional passphrase ("25th word") for extra security *Use Case* Paper wallets, offline storage HD wallets (Ledger, Trezor, MetaMask, etc.) *Recovery Method* Must know both encrypted key & passphrase Seed phrase (+ optional passphrase)
