Does an encrypted Bitcoin-Qt wallet generate BIP38 private keys?
I saw that Bitcoin private keys start with 5, i.e. unencrypted / no-BIP38 PKs, can be imported on several bitcoin wallets, e.g. Blockchain.info, Electrum, etc., and everyone with access to these unencrypted PKs can spent the bitcoins associated with them without entering a password to validate the transaction. While BIP38's private keys, i.e. those starting with 6, can be imported to several Bitcoin wallets,those ask the associated password in order to move the coins associated with them.
So let's say that someone would guess my Bitcoin-Qt's encrypted private key, and he imports it on blockchain.info or Electrum. Will he need to enter my password to spent the coins associated to my PK? In other words, do my encrypted Bitcoin-Qt private keys works like any BIP38 PK?
