user61762: I am aware that the introduction of BIP-38 resulted in a standard for passphrase-based encrypted private keys utilizing AES. What is not clear to me is whether these can be generated from HD wallets? Are the HD wallet seed-based private keys, then, considered encrypted private keys? Or do they follow the general private key format, since they are derived through their own HD wallets' processes? 

user48884: The private keys themselves can be generated with BIP 32 and then those private keys encrypted. Private keys generated with BIP 32 are not special private keys; they are just normal private keys and you can do exactly the same things to those private keys as you would to any other private key.
